Klean Kanteen Stainless Steel Water Bottle Classic with Loop Cap Brushed Stainless - 27 oz.
Klean Kanteen Stainless Steel Water Bottle Classic with Loop Cap Brushed Stainless is the original stainless steel hydration bottle. Their most popular size, the 27oz Klean Kanteen Classic is perfect for your on-the-go life. Whether you're trying to juggle a full day of classes or work, the kids' extracurricular schedules, or a trip to dog park between your workout and happy hour, just one or two fill-ups will help you stay hydrated and happy all day.
The bottle is made from high quality, 18/8, food-grade stainless steel that's totally free of BPA and other toxins. Because stainless steel itself is safe, they don't need to coat the inside of the bottle with a plastic or epoxy lining, which is one of the main differences between a stainless steel Klean Kanteen and aluminum bottles.
Klean Kanteen Classic bottles have three different cap styles: Sport 2.0, Loop and Flat. The revolutionary Sport Cap 2.0 effortlessly delivers a high flow rate that makes it easy to drink from your bottle without removing the cap. The Loop Cap is totally leakproof and has a durable attachment point so you can clip it on to just about anything. And the Flat Cap is low-profile, unobtrusive and leakproof.
All Klean Kanteen caps are made from polypropylene, a safe plastic that's free of BPA, phthalates and other toxins. But if you want to be sure your drink never touches anything other than stainless steel, the Flat and Loop caps are available in a stainless steel version for Klean Kanteen Classic bottles.
Food-grade stainless steel is used in the brewing, food and winemaking industries too. It's the material of choice because it doesn't retain or impart flavors. No matter how many times you refill it, no matter what you put into it, your 27oz Klean Kanteen Classic will keep your drinks fresh, crisp and clean tasting. Plus it weighs only 6 ounces and is durable and designed to last for years. All our caps are BPA-free too, and they offer stainless steel cap options for Classic bottles as well. The 27oz Classic is also available with the new and improved Sport Cap 2.0 that's six times stronger and more impact resistant.
The large-mouth design allows you to pour in big stuff like ice cubes, and makes cleaning your Klean Kanteen Classic as simple as scrubbing it out or throwing it in the dishwasher. Yet the slim design fits into most cup holders and the the Kanteen Bike Cage.

News in the outdoor industry has once again brought much attention and questioning about the presence of the chemical, bisphenol-a (BPA), in reusable bottles. In an August 19, 2009, article by SNEWS, popular bottle makers, Sigg and Laken, publicly acknowledged for the first time that every aluminum bottle made and sold by their companies prior to August 2008 was knowingly lined with an epoxy resin containing BPA. Many scientific studies indicate BPA has the potential to act as an endocrine-disrupter when ingested, and fetuses, infants, and children are most susceptible to develop negative human health effects associated with BPA such as diabetes, heart disease, cancers, infertility, obesity, and neurological disorders.
Klean Kanteen empathize with consumers who are now discovering the presence of BPA in their aluminum bottle liners, particularly when they believed they had specifically chosen a BPA-free option. Many years ago, their company recognized the growing scientific concern regarding human exposure to BPA; we introduced stainless steel bottles in 2004 specifically as an alternative to polycarbonate plastic and epoxy-lined aluminum that were the dominant materials for reusable bottles at the time. Since the news regarding Sigg and Laken has also raised questions about stainless steel bottles, we offer some clear answers to alleviate confusion.
Not all metal bottles are created equal when it comes to health and human safety. Ever since the very first Klean Kanteen was released in 2004, we have chosen to make our bottles from high quality, 18/8, food-grade stainless steel - a metal superior in both strength and safety that contains no harmful chemicals or toxins, including BPA. In fact, the National Toxicology Program recommends choosing glass, porcelain, or stainless steel containers to prevent exposure to BPA. And unlike aluminum bottles, there's no requirement for a liner in Klean Kanteens, since stainless steel is recognized around the globe as a safe, food-contact material. Sure it costs more to produce a stainless steel bottle compared to aluminum or plastic, but we've always thought you were worth it.
At Klean Kanteen, their goals are simple: to provide affordable, high quality beverage containers and accessories that are good for people, and good for the planet. They treat their customers like good neighbors, and their partners like dear friends.
They've always been stainless. Before Klean Kanteen, hydration bottles were made from either polycarbonate plastic or aluminum. We now know that both those materials are associated with a host of diseases and illnesses, info that wasn't common knowledge in 2004 when they released the first food-grade stainless bottle onto the market. But there were studies, even then, that worried us and caused us to doubt the safety of the existing bottles on the market.
The founders of Klean Kanteen wanted to give health conscious people a safe alternative to plastic and aluminum. So the very first Klean Kanteen was made from high quality, 18/8, food-grade stainless steel - a metal superior in both strength and safety that contains no harmful chemicals or toxins.
Now all those other companies that started out making plastic or aluminum bottles are crowing about their new stainless bottles. They got it right the first time because health has always been their top priority.
You don't pay for pretty. They offer a wide array of gorgeous colors and they use a safe, lead-free, acrylic paint. Fancy graphics often require complex processes and extra materials, which make them expensive to produce.
They invest in the highest quality materials and in designing a functional, durable bottle. Occasionally, they do release special edition bottles with graphics that promote projects, events and causes they believe in, which are in-line with their philosophy of health, sustainability and environmental awareness. But even then, their graphics are still printed with the same nontoxic paints at facilities that are committed to strong environmental standards.
Their curving corners and rounded threads make their bottles safe, easy-to-clean and sanitary. All the nice curves on a Klean Kanteen are no accident. Hard corners and sharp angles create a place where dirt and bacteria can stick. The threads on their bottles curve and sweep. They're also large and far apart so germs and other crud don't get stuck in the threads of the bottles or the caps.
A bottle's durability depends on the quality and thickness of the metal. The thickness of metal is called the gauge: the higher the number, the thinner the metal. They spent years testing bottles with different thicknesses of stainless steel to find the perfect balance between durability and weight. After thousands of scientific, and sometimes less scientific tests, they chose strong, thick steel that meets their rigorous standards. The gauge on their bottles is low, and that's a good thing. They're made to last a lifetime.
They don't cut corners with cheap materials. Klean Kanteen bottles have two types of thread designs, internal threads on the Classic bottles and external threads on the Wide bottles. Both types of threads are made using 100% stainless steel, not plastic or aluminum.
While it's more costly to make the threads on their bottles from stainless steel, the real challenge was in the design. On the Classic bottles, creating a cap option that was 100% stainless took serious engineering because both sets of threads, on the bottle and the cap, have to be perfectly formed. Designing the external threads you see on the Wide bottles also required meticulous craftsmanship, but allowed us to make a cap with a stainless interior that's standard on all Wide bottles.
Imitation of their innovative designs is the highest form of flattery. Being a leader has its own unique set of challenges. Klean Kanteen was the first company to make a stainless bottle for personal hydration. They were also the first company to introduce a truly functional sport cap, the Sport 2.0, that delivers serious flow even on a metal bottle you can't squeeze. The elegant Flip D-Ring Cap, available as an accessory for their Wide bottles, is another new design.
But they never release something before it's ready, so it's right the first time. It's one of the reasons Klean Kanteen products have a reputation for high quality. You can't copy that.
Klean Kanteen: the Original Stainless Steel Bottle
In 2004 Klean Kanteen introduced the first personal hydration bottle made from stainless steel to give health and environmentally conscious people an alternative to plastic. They have yet to see another bottle company, stainless or otherwise, that makes a product comparable to their high quality, handcrafted bottles or that commits to strong environmental and labor standards.
It's the healthiest, safest bottle you can buy.
Their bottles have always been made from toxin-free materials, with large-mouth openings and rounded corners and threads so they're easy to clean. They also offer all-stainless cap options in all bottle styles.
- Toxin-free materials
You never have to worry about the materials in a Klean Kanteen. Toxin-free materials: They did the research for you and selected high quality, 18/8, food-grade stainless steel for the bottles and BPA-free polypropylene (pp#5) for the caps. Quality stainless steel doesn't need a liner like aluminum bottles, so it doesn't retain flavors or make drinks taste funky.
- Curvy corners and rounded threads
It's easy to clean their bottles because they were intentionally designed with radius (rounded) corners. The bottle doesn't have any sharp edges or hard angles where dirt or bacteria can hide. They also use large, rounded threads that are easy to scrub out so dirt, bacteria and germs don't get stuck in the threads of either the bottles or the caps.
- Functional large-mouth openings
You can handwash their bottles or throw them in the dishwasher. Either way, the large-mouth design of both the Classic and Wide bottles makes it easy to keep them clean and sanitary.
- 100% stainless environment
All Wide bottles have a cap with stainless steel on the inside so drinks never touch plastic. You can order all-stainless caps for Classic bottles as accessories too, an option you won't find from other brands except Klean Kanteen imitations.
- Flavor free
The food-grade stainless steel they use doesn't need to be lined with plastic or baked-on epoxy like aluminum bottles, so you'll never have to check to make sure the inside of your Klean Kanteen is still safe and intact. Because their bottles don't have a liner, they don't retain flavors or make drinks taste funky either.
Klean Kanteens are handmade and designed to last.
When you buy a Klean Kanteen you're getting a handcrafted bottle designed to last a lifetime. They use an extremely high quality metal that will remain stain and rust resistant for decades.
- Handcrafted quality
Every Klean Kanteen is made from pieces of stainless steel welded together by hand then electropolished for a smooth, shiny finish.
- Made to last a lifetime
The walls of Klean Kanteen bottles are noticeably thicker than most copycat brands. It's a well-researched balance between weight and durability, so they don't dent easily. If you take care of your bottle, it can last a lifetime.
- Stainless forever
Not all stainless steel is the same. They make their bottles using an extremely high quality metal so their bottles stay stainless and shiny forever.
They don't greenwash. Klean Kanteens really are eco-friendly.
Klean Kanteens are made to be refillable and reusable so you'll never need to buy water in a plastic bottle again. The bottle itself is also 100% recyclable, and in keeping with their commitment to environmental sustainability, Klean Kanteens are manufactured responsibly in China at factories that are committed to strong environmental and fair labor standards.
- Refill, reuse, reduce
Refilling and reusing your Klean Kanteen instead of buying drinks in single-use plastic containers keeps thousands of plastic bottles from entering the waste stream.
- Klean in China
They work with their manufacturing partner in China toward achievement of strong environmental standards put in place to protect the earth, water and air and to reduce the environmental impact of the manufacturing process.
- Fair labor standards
They visit their factories regularly, sometimes unannounced, to make sure that the workers who handcraft each Klean Kanteen are treated well and paid fairly. They require fair labor standards, including the ethical treatment of factory workers, child labor rules, wages and benefits, health and safety.
- Fundamentally friends
They partner with a number of likeminded organizations including the Breast Cancer Fund, NatureBridge and Healthy Child Healthy World-organizations working to bring about environmental and social changes they support. They're also a proud member of 1% For the Planet.
Klean Kanteen, an industry leader at providing sustainable solutions to single-use plastic, recently completed requirements including an in-depth assessment process to become a certified Benefit Corporation. Certified B Corporations are progressive businesses focused on, above all else, solving social and environmental problems. The comprehensive assessment through B Lab, a nonprofit organization that certifies B Corps, vets all aspects of company structure from human resources and codes of conduct for the supply chain, to sustainability efforts. Klean Kanteen's mission lives true in the definition of a B Corp and the company is proud to be part of this growing and cutting-edge movement.
"Everything from our global production process and our fair labor and environmental standards, to our company structure and shared individual responsibility both inside and outside of the office is grounded in the same fundamental values from which B Corp was conceptualized", says Danielle Cresswell, Director of Sustainability at Klean Kanteen.
Klean Kanteen products are not just a feel good choice, they are progressive, functional designs that perform a task much better than the paper, plastic and aluminum options. Not all alternatives to single use products are created equal- it is paramount to the Klean Kanteen mission to offer only Responsible Solutions that are designed with health, safety and sustainability front of mind.
"Working to earn a spot within the emergent B Corp community is not simply a badge of honor for our company," stated Scott McGuire, Director of Sales and Marketing, "but the assessment process became a systematic way for us to enhance our already established processes and procedures while also setting a foundational structure for intentional growth in the future."
As an industry leader, it is Klean Kanteen's hope that stricter standards on corporate transparency as well as the growing demand for safe, healthy alternatives to plastic will help drive the industry forward. Growing consumer awareness for the hazards of everyday toxins will lead to the identification of greener chemistry and a broader range of safe, sustainable alternatives for all single-use products.
Frequently Asked Questions
The Klean Kanteen Difference
There are so many reusable bottles to choose from. Why should I buy a Klean Kanteen?
In 2004 when they released the first Klean Kanteen bottle, the only other options out there were polycarbonate plastic bottles or aluminum bottles lined with plastic resin or epoxy.
The reason Klean Kanteen exists is because they wanted to give consumers a safe, healthy, BPA-free alternative to plastic, a bottle that's reusable, environmentally sustainable and durable enough to last a lifetime. They chose to make their bottle from high-quality, 18/8, food-grade stainless steel, one of the healthiest and most durable materials available.
Some of the key features that set Klean Kanteen apart include easy to clean rounded corners and threads; high quality, food-grade materials that are BPA-free and don't retain or impart flavors; and durable, all-stainless construction including bottle threads.
They also set up their company and their manufacturing to be environmentally responsible and sustainable from the beginning. They oversee their manufacturing every step of the way, from the sourcing of the basic materials to the retail floor and they're constantly working to cut waste and operate more efficiently.
What kinds of bottles does Klean Kanteen make and what are the differences?
Klean Kanteen has four products lines: Kid Kanteen, Kanteen Classic, Kanteen Wide, and Kanteen Wide Insulated. The Kid Kanteen currently consists of a Sippy for toddlers. The Kanteen Classic is the original Klean Kanteen, the one with the longneck design. The Kanteen Wide is a wide-mouth bottle, and the Kanteen Wide Insulated has the same design as the wide-mouth bottle but uses double-walled, vacuum insulation for amazing insulating performance. Visit the Kanteen 101 pages to compare the Classic and Wide lines, and the main Kanteen Wide Insulated page to learn more about their insulated bottles.
Which is better, stainless or aluminum?
While aluminum is lightweight, it can leach harmful substances and chemicals when it gets hot or comes in contact with anything acidic. Studies have also linked aluminum exposure to Alzheimer's disease. To ensure that the drinks inside aluminum bottles are safe, the bottles must be lined with something.
The most common materials used to line aluminum bottles include plastic resins or baked-on epoxy, both of which can leach BPA and other harmful chemicals or can get scratched, exposing the aluminum underneath. Ceramic is another material used to line aluminum bottles, but it's more rigid and can crack.
Of even greater concern is the fact that many companies won't release information about what the liner on their aluminum bottles is actually made from. The liner can also retain flavors, which can make your drinks taste funky.
The stainless steel used to make Klean Kanteens is time-tested, safe and completely free of BPA, phthalates, lead and other harmful substances. It's fine for acidic beverages or foods, and doesn't retain or impart flavors. That's why it's the material most commonly used in food preparation and by the brewing and wine-making industries.
What's the story on the Sport Cap 2.0?
Klean Kanteen redesigned the sport cap, releasing the Sport Cap 2.0 in the spring of 2009. The Sport Cap 2.0 performs extremely well, delivering a high flow rate (3x greater than the original cap) with almost no effort. It's also much quieter than the old sport cap, though the air flowing back into the bottle as you drink does make a soft noise.
Health and Safety
Why was the Sport Cap 2.0 recalled and where can I get more information?
Klean Kanteen received six consumer reports relating to the spout tip of Sport Cap 2.0 breaking or cracking after being dropped, which could pose a potential choking or ingestion hazard. There have been no incidents of factual choking or ingestion reported.
They replaced the spout tip with a new one made from the same BPA-free, polypropylene, but the formulation is slightly different. The new spout tips are six times more impact resistant and stronger than the original spout tip on the Sport Cap 2.0.
Visit their Safety Notice page for information about the recall including how to identify if you've got a recalled cap and how to get your recalled Sport Cap 2.0 replaced.
Do Klean Kanteens have BPA?
No way. Every Klean Kanteen ever made is totally free of BPA and other harmful substances.
The whole reason they founded this company was because they read the early studies linking BPA to a number of illnesses and they wanted to give consumers a safe, healthy alternative to plastic and lined aluminum bottles.
They chose 18/8, food-grade stainless steel instead of aluminum or plastic because the metal is inherently safe and toxin-free. Stainless steel is made of many elements and minerals that come from the earth, including some of the very same minerals recommended by the FDA as part of a healthy human diet.
Food-grade stainless steel is used in the brewing, food and winemaking industries too. It's the material of choice because it doesn't retain or impart flavors.
All their caps are BPA-free polypropylene (pp#5) too, and they offer stainless steel cap options for Classic bottles as well.
Do Klean Kanteens have a liner?
No. All Klean Kanteen products are made from high quality, 18/8, food-grade stainless steel that's totally free of BPA and other harmful substances.
Because stainless steel is inherently safe, they don't need to coat the inside of the bottle with a plastic or epoxy lining, which is one of the main differences between a stainless steel Klean Kanteen and aluminum bottles.
Why do Klean Kanteen caps have plastic at all?
Caps made from solid stainless steel would be both heavy and costly. Caps made from safe, BPA-free polypropylene (pp#5)are lightweight and also cost-effective, enabling Klean Kanteen to create a handcrafted product of exceptional quality at a reasonable price.
In the case of the Sport Cap 2.0, it's also a safety issue because people drink from their bottles while engaging in sports like cycling and running. Polypropylene is very durable, but it's also a softer plastic, which means you're less likely to damage your teeth if you hit a bump on the trail while you're drinking.
On Classic bottles, many people disliked the squeaking of the stainless caps, which are metal-on-metal because of the internal thread design of the bottles. Klean Kanteen now offers all cap styles for Classic bottles in an all-polypropylene option.
The caps for all Klean Kanteen Wide bottles have stainless steel on the inside. You can order stainless caps for Classic bottles as accessories in the Flat and Loop style.
Are the polypropylene (pp#5) caps safe?
Klean Kanteen uses polypropylene (pp#5) because it contains no Bisphenol A (BPA), a chemical that leaches from some kinds of plastic and has been linked to various diseases. Polypropylene has no known leaching characteristics and is softer than other types of plastic.
The caps for all Klean Kanteen Wide bottles have stainless steel on the inside and stainless cap options are available as accessories for the Classic bottles in the Loop and Flat cap styles.
What is stainless steel and what does 18/8 stand for?
Stainless steel is an iron-containing alloy made from some of the basic elements found on earth: iron ore, chromium, silicon, nickel, carbon, nitrogen and manganese. The properties of the final metal change depending on varying amounts of these elements. More than 57 stainless steels exist and are sold as standard alloys on the market.
Klean Kanteens are constructed from high-quality, 18/8, food-grade stainless steel. The numbers stand for the percentages of chromium and nickel in the steel, 18% and 8% respectively. Chromium increases the metal's hardness and nickel gives it strength. Together they also make stainless steel highly resistant to stain or rust.
Stainless steel is easy to clean, durable, inert and sanitary. That's why it's the material of choice among the food processing, dairy and brewing industries.
What is nickel and how can it affect my health?
Nickel is a naturally abundant element found in the earth's crust, soil and ocean floor. It is generally resistant to corrosion and is therefore used to make metal alloys such as stainless steel.
Approximately 10-15% of the population is sensitive to nickel, but the health effects of nickel are highly dependent on the manner and degree of exposure. The stainless steel used to make Klean Kanteens has a low nickel content and is the preferred material used by breweries and dairies.
Do Klean Kanteens have hexavalent chromium, and could I be exposed to it by drinking from a Klean Kanteen?
Stainless steel does not contain hexavalent chromium; so you don't need to worry about exposure to hexavalent chromium from your Klean Kanteen. Hexavalent chromium has been found in tap water in some municipalities. They recommend that you check with your local water provider and get a copy of their most recent water quality reports. They're public record and should be made available to you upon request. The tests may even be available online.
Does the paint on a Klean Kanteen contain lead?
No way. When they introduced their colored bottles, they wanted to find a safe and durable paint that also looks fantastic. They reviewed and tested dozens of different paints and selected an acrylic paint that contains no toxins or lead. They test the paint regularly and though it is safe, they recommend the Brushed Stainless finish bottles for small children who like to chew on things.
My child chewed on a Klean Kanteen and might have eaten some paint. Should I be concerned?
No. The paint on Klean Kanteen bottles is a nontoxic, acrylic, resin-based finish that's mostly water and is totally free of lead and toxic chemicals. So you've got nothing to worry about if your child ingested some paint! That said, they do recommend the Brushed Stainless finish for small children who like to chew on things.
Why are Klean Kanteens made in China?
The very first Klean Kanteen was created to promote healthy living and respect for the environment by giving people an affordable alternative to plastic and lined aluminum bottles.
Klean Kanteen has always shared many of the concerns you, their customers, have expressed about manufacturing the bottles in China. Before a single bottle was ever produced, Klean Kanteen set in place checks and balances to ensure that their bottles are produced safely, sustainably and that the people making Klean Kanteens are treated well and paid fairly. By manufacturing in China, Klean Kanteen can provide a handcrafted bottle of exceptional quality at a reasonable price.
For more information about their commitment to operating Klean Kanteen sustainably and manufacturing their products in a way that's environmentally responsible with fair labor and human rights standards, read their sustainability and responsibly made pages.
Is Klean Kanteen's stainless steel from China safe?
Yes. They have representatives from Klean Kanteen living in China who visit their factories regularly. They work as liaisons to ensure all Klean Kanteen products are produced with respect for the environment and that the workers in the factories are safe, protected and paid a living wage. In addition, a rotating group consisting of the owners and various employees visits the factory two to three times a year.
They currently perform regular product testing through third-party, accredited laboratories to meet regulatory requirements and their own high standards for product safety.
Klean Kanteen is and will continue to be one of the safest and most sustainable beverage containers on the market.
Using and Cleaning your Klean Kanteen
Can I fill a Klean Kanteen with acidic beverages such as apple juice or orange juice?
Yes. Acidic beverages will not corrode or damage the high-quality stainless steel.
Can I use a Klean Kanteen for milk, breast milk or formula?
Absolutely. Your Klean Kanteen is food-grade stainless steel, the same stuff they use in the dairy industry.
Can I use a Klean Kanteen for carrying alcohol?
Yes. In fact, they make a special bottle, the Wine Karafe, designed just for wine. They've also heard that many people use the 12oz bottles to carry spirits or the 64oz Wide as a Growler for a tasty half gallon of beer.
Do Klean Kanteens sweat?
It depends on which bottle style you're using. Their Classic and Wide lines are single-walled.If you have a cold drink in them and it's hot out, you're going to have condensation build-up on the bottle.
Their Wide Insulated bottles are made using durable, double-walled construction and vacuum insulation, which has amazing insulating properties. Because they're insulated, these bottles will not have condensation build-up on the outside, regardless of what's inside them or the temperature outside.
The best solution to naturally occurring condensation on Classic and Wide bottles is to put your Klean Kanteen in an insulated sleeve such as the insulated totes made by their partner, Built. Whatever size Klean Kanteen you prefer, there's a Built tote in a color and style you'll love. Check them out on their accessories page.
Can I put hot liquids in my Klean Kanteen or use it like a thermos?
If you have a Kanteen Wide Insulated bottle, absolutely! Their high-performance, double-walled, vacuum insulated bottles are designed to function as a thermos, a to-go mug and food storage container and will keep contents hot or cold for up to six hours and iced drinks chilly for up to 24.
They do not recommend using single-walled Klean Kanteen Classic or Wide bottles for hot beverages because you can burn yourself. Warm beverages can be used at your own personal comfort level. They're fine for cold beverages, but unlike the Insulated Kanteen, condensation will form on the outside.
Can I put my Klean Kanteen in the freezer?
No. The force of liquids expanding as they freeze can cause your Klean Kanteen to become deformed and can also break the weld that holds the bottle together, so they strongly advise against it. Freezing any Klean Kanteen (Classic, Wide or Insulated) will void the one-year warranty against manufacturer defects.
Can I put my Klean Kanteen on a stove?
In a pinch, single-walled Kanteen Classic and Wide bottles with the Brushed Stainless finish can be placed on a fire or a stove as long as you take the cap off. Do not do this with a colored bottle, as it will damage the paint.
But it's VERY important that you know what kind of bottle you have because this is absolutely NOT an option with an Insulated Kanteen. Heating a Kanteen Wide Insulated will damage the bottle and voids the one-year warranty.
It's pretty easy to tell what kind of bottle you have, even if you've had your bottle so long the logo's worn off. Insulated bottles only come in the wide-mouth design, so if you have a Classic, a bottle with a long neck and a small rolled lip at the edge, you have a Classic. Insulated bottles also have a separate, extra shiny piece at the bottom and come in different sizes (12oz, 16oz, and 20oz) than the single-walled Wide bottles (12oz, 18oz, 27oz, 40oz and 64oz).
How do I clean my Klean Kanteen and my caps?
Kanteen Classic and Wide bottles in Brushed Stainless are dishwasher safe. They recommend handwashing colored bottles and Insulated bottles.
Classic Loop and Sport Caps made of polypropylene (pp#5), and the Wide Café Cap are dishwasher safe. The Café Cap is also dishwasher safe and the rotating piece on the top also pops out for thorough cleaning.
All Classic and Wide caps with stainless steel on the inside should be handwashed. The Classic polypropylene Flat Cap should also be handwashed. An easy way to remember is that if your cap is all plastic and hollow on the inside, it can go in the dishwasher. Otherwise, handwash it.
For daily cleaning, just rinse your bottle with warm, soapy water and let it drain and dry in your dish rack with the mouth downward so water can drain out.
For thorough cleaning, you can use warm, soapy water and a bottle brush. They also recommend an old-fashioned cleaner: diluted vinegar or water and baking soda.
I dropped my Klean Kanteen and dented it. Is there any way to get the dents out?
Klean Kanteen bottles are made of heavy gauge stainless steel and outperform all other metal bottles in independent tests. But they can dent if you drop them. Their one-year warranty covers manufacturer's defects only, not damage caused by using or dropping your bottle.
If you dropped your bottle and dented it, odds are the dent is inward. In some cases you can put a wooden dowel or a wooden kitchen spoon inside the bottle and tap on the other end with a hammer to push the dent out. DO NOT use a metal object to bang the dent outward as the metal can get inside your Kanteen. You can also further damage or even puncture your bottle.
Even if you've dented your bottle, it's still totally safe and free of harmful substances. Because every Klean Kanteen made if 18/8 food-grade stainless steel through and through with no liner on the inside, a dent, no matter how large, will not change the composition of the metal.
