Water
DO -
Use filtered water
Clean bottle with uncooked rice (shake well)
Clean spout with Q-tips or bottle cleaner
Change water and clean regularly
Always check the water bottles to make sure they are full and the spout isn’t stuck or leaking
DON’T -
Don’t add vitamin C liquids - or any other type of drops/medication - in the water (vitamin C degrades rapidly in water and light, accurate dosing cannot be guaranteed, and it can change the taste, which discourages adequate water intake)
Don’t use distilled water
