It seems like everyone has a go-to reusable water bottle. Whether you're partial to a Stanley cup, an Owala, or a Hydroflask, there's one fact that unites us all: We probably need to wash them more frequently. I carry a reusable bottle with me almost constantly, so I tapped an expert to find out how often I should clean my water bottle.
While you would probably avoid drinking from a cup that hadn't been washed in several days, plenty of people will drink from a water bottle that hasn't been washed in a while. Kitchen Lab Director Nicole Papantonioushared that water bottles should be washed more frequently than you might expect. You don't need to wash it every single time you use it, but it's also not a great idea to forgo washing for more than a few days. Bacteria can grow on or in the bottle, which can make you sick.
Below Papantoniou shares how often you should be cleaning your water bottle. If you're wondering exactly how often you're supposed to be washing or cleaning other things in your home, read up on the appliances you should clean more often and how frequently you're actually supposed to wash your towel.
It's easy to assume a water bottle is clean after simply refilling it with water day after day. You are the only one drinking out of it, after all. But if you tend to go days without giving it a good wash, you might want to work it into your daily routine.
"I’d recommend cleaning your water bottle daily, but I’ll admit that sometimes I’ll go two or three days tops without washing it," says Papantoniou. "Bacteria can build up easily, which can make your water taste bad and can even cause sickness."
Cleaning your water bottle every day might seem inconvenient, but most tumblers nowadays are dishwasher-safe. Just throw it in there at the end of the day with the rest of your dishes so it's fresh and clean the next morning.
Tip: Always check the manufacturer's instructions before putting your water bottle in the dishwasher.
If your water bottle isn't dishwasher-safe or you want to give it an extra deep clean, here are a few steps to follow when washing by hand.
- Dissemble all pieces of the water bottle before cleaning.
- Wash the outside of the bottle using a sponge and hot, soapy water. Clean the inside with a bottle brush.
- Pay special attention to the mouthpiece and all crevices of the bottle, including the straw. “I always give my straws a good once-over with a straw brush to remove any buildup,” says Papantoniou.
- Let all pieces of the water bottle dry. “Mold can grow under silicone pieces if they're not removed and allowed to dry completely," says Papantoniou.
