20 cleaning tablets for all Sigg drinking bottles. For optimal and gentle cleaning of Sigg drinking bottles, it is recommended to thoroughly clean the bottle and drinking cap separately by hand after each use with Sigg cleaning products or regular dish soap in warm water. For thorough cleaning, the specially shaped Sigg cleaning brush, designed for Sigg drinking bottles, is ideal. After cleaning, allow to air dry or store, so that drinks from a Sigg always taste fresh.
