When you think of germy places in your home, you probably think of your toilet, your door handles or your phone. But you should include your reusable water bottle on that list – especially if you’re not washing it regularly. Bacteria from our mouths can be deposited inside every time we take a swig, and the outside of the bottle can pick up germs and sweat if you take it with you to the gym or on your commute.  

Ideally, you should clean your water bottle with dish soap and hot water every day. But for times you need to go a step further, we’ll show you how to sanitize and disinfect it with bleach.

Frequently asked questions

Can you put water bottles in the dishwasher?

It depends. Check the bottom of your bottle for care instructions or symbols. Some bottles will say “dishwasher safe” or “top rack only,” or you may see a square with plates in the middle, which means it’s safe to wash on the top rack. If you are unsure, it’s best to play it safe and hand wash only to avoid any warping or discoloring of the material.
