How to clean SIGG and other aluminium bottles

Whether your bottle is a Klean Kanteen or other stainless steel bottle or a 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, so the number one rule is to let your bottle dry out completely on a regular basis.

Wash your bottles with warm, soapy water at the end of every day, rinse in fresh water, and let the bottle air dry upside down with the top off.

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.

We recommend using filtered water where possible.   It tastes so much better without chlorine–but also because water contains different minerals in every area and this may affect what happens inside your bottle.   Biome sells a popular range of hand made ceramic water purifiers.  Spots inside your water bottle that look like “corrosion” are most likely a mineral deposit.

Try also SIGG cleaning tablets and 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.

We recommend not putting your reusable water bottle into the dishwasher.  The dishwasher can damage the external paint coating and because most dishwasher powders are caustic, they will eat into the paint and metal.   Your outer colourful coating will deteriorate much faster when exposed to the heat of dishwashers.  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.
