Reusable water bottles have become a daily accessory for many people. They travel to work, school, the gym and sporting events, sit beside the bed at night and ride in cup holders throughout the day. But while most people remember to refill their bottle, they may not remember to wash it. That can turn a container meant to encourage a healthy habit into a welcoming environment for bacteria and mold.
Every time someone drinks from a bottle, bacteria from the mouth can be transferred to the lid, straw or drinking surface. Hands can introduce additional germs when opening the bottle, adjusting a straw or carrying it throughout the day. Add moisture and a closed container, and microorganisms have an opportunity to grow. Dumping yesterday’s water, giving the bottle a quick rinse and filling it again may seem sufficient, especially when the bottle contained only water. However, rinsing alone may not remove bacteria or buildup.
Reusable bottles should be washed regularly with dish soap and water. A bottle brush can help reach the bottom and sides of containers with narrow openings.The lid deserves just as much attention as the bottle itself. Straws, mouthpieces, rubber seals and silicone gaskets can trap moisture and residue in small spaces. Removable pieces should be taken apart periodically and cleaned individually. If the bottle is dishwasher-safe, the dishwasher can make cleaning easier, but owners should check the manufacturer’s instructions first. After washing, allow the bottle and its parts to dry completely before putting everything back together.
An unpleasant smell or visible residue is an obvious indication that a bottle needs attention, but a bottle does not have to look dirty to contain germs. Bacteria and mold are not always visible, which is why regular cleaning is more effective than waiting until something looks or smells wrong. Bottles used for beverages other than water need particular attention. Sports drinks, flavored waters and other beverages can leave residue behind, providing even more material for microorganisms to grow.
Sharing water bottles should also be avoided, since drinking from the same container provides an easy opportunity to exchange germs. The easiest solution is to make cleaning the water bottle part of the daily routine. Wash it with the dinner dishes, put dishwasher-safe bottles in the dishwasher at night or keep a bottle brush near the kitchen sink as a reminder.
Reusable water bottles remain an excellent way to keep water nearby and make staying hydrated easier.
Just remember that refilling the bottle isn’t the only daily habit that matters.
Sometimes, it needs a bath, too.
