You can roughly calculate how much water you need per day in the water requirement calculator.
Wash after every workout with warm water and mild detergent, and once a week with a cleaning brush and a cleaning tablet (baking soda or special tablets). Leave it open to dry — a damp closed bottle is the best place for bacteria. Do not try to put cold drinks into the bottle straight from the refrigerator if the manufacturer does not recommend it.
