Caring for your Water Bottles

Cleaning your water bottles

Plastic water bottles can periodically develop unpleasant odours and/or tastes. These can result when bottles are stored incorrectly, cleaned infrequently or used to carry liquid, which may impart a flavour or odour.

Most plastic water bottles are made out of either polyethylene plastic (which tends to be cloudy in appearance) or polycarbonate (which tends to be clear). Most hydration system bladders have polyethylene linings, which retain tastes and odours more easily than polycarbonate. But all plastic bottles are susceptible if cared for incorrectly.
