Klean Kanteen‘s reusable water bottles have changed the way people drink their coffees, teas and other beverages. From a single-walled container to double-walled vacuum insulated bottles, consumers have easy access to safe and healthy drinks.

These remarkable reusable water bottles from Klean Kanteen are made from food-grade 18/8 high quality stainless steel. They are rust-proof, durable and free from BPA. The interior is even electropolished for a safer drinking experience.

Just like any house wares, reusable water bottles must be washed and cleaned. Failure to do so may have effects to both your health and the integrity of your water bottle. These can include bacteria, mold and mildew growth and residue build-up could lead to coat corrosion and food poisoning. Dairy products such as milk and sugar can settle to the bottom section of your bottle and become a gunk when left unwashed for days. This gunk can house bacteria that can cause gastrointestinal problems.

A clean reusable water bottle will keep the contents fresh. It will also help in keeping your bottle reusable for the next years to come.

So how do you clean your Klean Kanteen water bottle?

Removing Residue, Dirt and Odor

Residues would start to build up in your water bottle if you leave it unwashed for days. The best way to remove any residue and unwanted sediments is to soak your bottle in hot water mixed with either vinegar or baking soda, both of which are excellent cleaning agents and are widely known for their natural antibacterial properties.

Do not use any strong chemical-based cleaning solutions like bleach because they might be too corrosive and could cause irreparable damage to your bottle. Additionally, avoid using any abrasive cleaning products like steel brushes. If you want to scrub off tough stains, use a sponge or soft bristle cleaning brush instead.

Amazingly, baking soda and vinegar can also help in removing bad odor. Although the Klean Kanteen bottles are made from high-quality stainless steel, you can be assured of that there is no altering of flavors or imparting of flavors. Hence, there is no odor left. But sometimes, odor can linger and if this happens, baking soda and vinegar are excellent agents.

Clean with warm mild soapy water

Klean Kanteen water bottles should be cleaned and washed regularly with a warm soapy water. Use mild soap like Castille and avoid any detergents because they come off strong, leave residue and even deteriorate the bottle in the long run.

Warm and mild soapy water can gently clean the vessel, remove grime, gunk and even grease. You can also use the same solution in using a bottle brush or sponge. These two are excellent companions that can help remove stubborn dirt. A bottle brush will also help clean hard to reach areas specially the bottom part where grime and gunk usually settle. With soapy water in your bottle, give it a good vigorous shake and repeat until all dirt and residue are removed.

Detach removable parts

When cleaning water bottles, it is recommended to remove the parts and accessories. It is because germs and bacteria can thrive and hide in the nooks and crannies of these parts. Some can even settle if they are not thoroughly inspected and checked. Lids and caps can be cleaned separately with a sponge or a scourer.


The easiest way of cleaning a Klean Kanteen water bottle is to pop it inside the dishwasher. Make sure to keep it upright and to remove the cap or lid. The only downside to using a dishwasher is that some areas can’t be cleaned properly. It is somehow necessary to do a deep cleaning once when needed.

If your Klean Kanteen water bottle has a coating on the outside surface, it should never be cleaned using a dishwasher. It is because it can ruin the coating. Always read the care instructions of your bottle and check if it’s dishwasher-safe.

Air drying

Don’t forget to air dry your reusable water after cleaning and washing it. Tip it upside down on a drying rack and allow it to air dry. You can also use a kitchen towel to dry your reusable water bottle.
