Frequently Asked Questions

1.Can I put hot liquids in my Klean Kanteen Classic or Wide Mouth bottle?
No. Klean Kanteen Classics are single walled and not for use with HOT liquids. Warm beverages can be used at personal comfort level. If you are looking for a container to store hot liquids (or cold) you want an Insulated Klean Kanteen.

2.Can I put my Kanteen in the freezer?
No. Never freeze your Klean Kanteen. Damage is very likely and it will void the warranty.

3.Can I put my 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. Klean Kanteen and Little Acorns to Mighty Oaks cannot be held responsible for damage to yourself or your Klean Kanteen ifyou place your Klean Kanteen on a heat source.

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).

4.Why is the sippy spout made of plastic and not stainless steel?
Your teeth. The sippy adapter and hard Avent sippy spout (green) are made from
polypropylene #5 because it has no known leaching characteristics and is softer if you hit it on your lips or teeth. The soft Avent sippy spout (white) is made from Evoprene which is also an inert non-leaching plastic, free of PVC, BPA and Phthalates.

5.What is stainless steel?
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. Properties of the final alloy are tailored by varying amounts of these elements. There are more than 57 stainless steels recognized as standard alloys on the market. Klean Kanteen's are constructed from high quality sanitary grade 304 stainless steel which has a low nickel content. Stainless steel has excellent resistance to stain or rust due to its chromium content making it a material of choice among the food processing, dairy and brewery industries. Stainless steel is easy to clean, durable, inert and sanitary.

6.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. Thehealth effects of nickel are highly dependent on the manner and degree of exposure, according to the Agency for Toxic Substances and Disease Registry (ATSDR), a department of the U.S. Dept. of Public Health and Human Services. The ATSDR warns that environmental exposures may arise from wearing costume jewellery, handling coins or from inhaling dust near nickel industries. The most common reaction to handling nickel is a skin rash at the site of contact. Less frequently, those sensitive to nickel have asthma attacks after inhaling dust containing nickel. Klean Kanteens are constructed of high quality, sanitary grade 304 stainless steel. 304 has a low nickel content and is preferred by breweries and dairies.

7.Will the stainless steel react with acidic beverages?
No.

8.Why is the Kanteen made in China?
The Klean Kanteen is made "responsibly" in China because one of the founding principles was to produce an economically priced high quality stainless steel bottle as an alternative to plastic and lined metal containers therefore promoting healthy living with respect for the environment.

Klean Kanteen's' preference from the outset has been to produce their bottles closer to home but extensive research in the manufacturing sector left them resolute that their bottles can not be made closer to home at a reasonable price without sacrificing quality and safety, something they are steadfast against.

9.Is the Klean Kanteen factory safe?
Yes. Klean Kanteen visit their manufacturing facilities 4-5 times per year and perform audits every six months to ensure all of their products are produced with respect for the environment and fair labour standards, including: the ethical treatment of factory workers, child labour, wages/benefits, health and safety, etc. Additionally, they do regular lab testing on random shipments through a lab in the U.S. to ensure their products are made per their specifications, are free of hazardous substances such as lead, and do not leach chromium, manganese, etc.

We believe that the Klean Kanteen is and will continue to be one of the safest and environmentally conscious beverage containers on the market today while upholding stringent design and manufacturing standards.

10.Is the Klean Kanteen Classic/Wide a Thermos?
No. The Klean Kanteen Classic and Klean Kanteen Wide bottles are single-walled and have zero insulating properties. If you pour boiling hot liquid into your a Classic or Wide bottle it will be too hot to handle directly. The single-walled construction allows for more volume and the option to put your Kanteen on a flame. If you are looking for a container to store hot liquids (or cold) you want an Insulated Klean Kanteen.

11.How do I clean my Kanteen?
Klean Kanteen's are dishwasher safe (washing caps in the dishwasher is not recommended because H2O can squeeze itself into the cap) or easy to clean with a bottle brush and mild soap. We recommend an old fashioned cleaner: white vinegar and baking soda.

12.Why is stainless steel better than aluminium?
Aluminium although light weight has to be lined with something to make sure the contents are safe for drinking. Usually it is lined with baked on epoxy (toxic) or ceramic (can crack).

13.Is the Klean Kanteen Sippy leak proof?
Klean Kanteen was originally designed as a sports bottle, and they have made a special 'sippy adapter' which is used in conjunction with the 'Avent' Magic Cup sippy spout. While the Klean Kanteen and the 'sippy adapter' are leak proof, the 'Avent' spouts are not guaranteed to be leak free. (During 'Little Acorns' product trials it was found that occasionally a few drops of water come out of the 'air' hole)

14.Does Klean Kanteen have a metallic taste?
It has been reported that a small percentage of people with discerning taste buds do notice a slightly metallic taste in the water from the Klean Kanteen, but this problem is very easily fixed. Before you use the Klean Kanteen for the first time (or any time you think there is a metallic taste) put 2-3 tablespoons of white vinegar into your Kanteen, fill it with water put the lid on and give it a quick shake, then rinse out, the vinegar will get rid of the metallic taste.

15.Does the paint on a Kanteen contain lead?
When Klean Kanteen released their coloured bottles, the most important thing to them was to find a safe and durable paint that also looked dynamite. They reviewed and tested dozens of different paints and selected an acrylic paint that contains no toxins or lead.
Klean Kanteen test the paint regularly and they're in the process of getting it certified by NSF International, an organization that helps protect the public by certifying products and developing national and international standards governing the production of food, water and consumer goods.
Though our paint is safe, we recommend our stainless steel finish bottles for small children who like to chew on things.

16.My child chewed on a coloured Klean Kanteen and might have eaten some paint. Should I be concerned?
No. The paint on Klean Kanteen bottles is a non-toxic, 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, we do recommend the stainless steel finish bottles for small children who like to chew on things.

17.What do you consider normal wear and tear for the paint on coloured Klean Kanteens?
Under normal use, the paint on the new coloured Klean Kanteens will not flake or chip off. When Klean Kanteen tested paints for their coloured bottles, safety was their first concern but durability was a close second.
The paint performs well in lab tests and we at Little Acorns to Mighty Oaks also use the coloured bottles so we've been putting them to the test in the real world too. Sure, if you drop your Klean Kanteen or jam it into a metal water bottle cage, you can scratch it. It's also possible to scrape off the paint if you try hard enough, just like any other painted surface.
But if your paint is flaking or peeling off, you might have gotten a bottle from a bad batch, which does happen occasionally. If that's the case, it's covered by the Klean Kanteen warranty and we'll replace it at no cost to you.
To prolong the life of your coloured Kanteen, we recommend hand washing it with mild detergent. If you want the ultimate finish in terms of durability, you can't beat our original electro polished Kanteens.

18.Are the sports caps leak-proof?
Not completely. Because Klean Kanteen bottles don't flex like a plastic bottle, the sports cap has been designed with a valve to let in air so you can drink from it easily. This valve can sometimes leak if the bottle is on its side or upside down.
