We would suggest following our daily cleaning routine: Wash your reusable water bottle at least once per day. Fill the bottle with warm water and a squirt of dishwashing liquid, not forgetting to remove the silicone ring as part of this process. Using a bottle brush, scrub the walls and bottom of the bottle. Be sure to clean not just the inside but also take extra care of the lip of the bottle and more importantly leave to dry. Bacteria and mould can thrive in a water bottle thanks to its moist environment. Please be aware if the bottle is left permanently damp then mould will occur.
