The Pura UVC Bottle keeps your water bottle sanitised and clean at all times thanks to its Automatic Deep Clean Function that activates every 6 hours, so you won't need to clean the inside of the bottle if you're filling up with water. 

Soups and other homely liquids, will need a good clean after use with your usual detergent and water, or your bottle can be popped into the dish washer. 

Although the bottle and the cap are IP65 (water-proof) we advise not to clean the cap (where the UVC LED chip is embedded) with any chemicals or detergents.  The cap doesn't require any special cleaning other than occasionally with water.
