Whether your bottle is a Klean Kanteen, or other stainless steel bottle , SIGG aluminium bottle with lining or a BPA free plastic water bottle, it is important to stop mould and other deposits forming inside the bottle. Any material kept constantly wet will breed bacteria.
Wash your bottles with warm, soapy water at the end of every day and let the bottle air dry upside down with the top off. We of course recommend eco friendly mild dishwashing detergent!
Should any mineral deposits or lime scale form inside, fill your clean bottle with Distilled White Vinegar (no other kind) and let soak for 24 hours. Then rinse the bottle with warm water and one tablespoon of bicarbonate of soda and let dry. Spots inside that look like "corrosion" are most likely a mineral deposit.
We recommend using filtered water where possible. It tastes so much better--but also because water contains different minerals in every area and this may affect what happens inside your bottle.
You can also try SIGG cleaning tablets and specially-designed SIGG cleaning brush on all drink bottles. Please only ever use a soft brush on SIGG so as not to damage the lining. Stainless Steel bottles can handle a hard brush. There is also a nifty thin straw cleaning brush that works for straws and sippy tops.
While all bottles are technically dishwasher-safe, we recommend not putting them in a dishwasher. The dishwasher can damage the external paint coating and because most dishwasher powders are caustic, they will eat into the metal. Tops should also not be put through the dishwasher because extreme heat expands and deteriorates the plastic.
Never freeze bottles as metal can split even with only a little water inside. Trust us, we have seen many bottles that expanded and split. Water does not always expand in a predictable direction! Even stainless steel bottles are not suitable to freeze.
If you want to keep your liquid extra cool, buy a wide mouth bottle from Klean Kanteen or SIGG that has an opening big enough for ice cubes - and actually makes the bottle easier to clean also. I recently heard there are water bottle ice cube trays to make long skinny ice blocks for putting into your water bottle.
