The unassuming water bottle, previously only common at sporting events and gyms, has ridden the fitness wave to become just as fashionable as athletic apparel, step counters and tennis shoes. While everyone agrees that staying hydrated is important for good health, reusable water bottles can become filled with germs and bacteria. To keep your containers hygienic and prevent illness, you need to clean them inside and out with a bottle brush.

Clean your water bottle regularly
Because water bottles are placed on surfaces that can include gym floors and public tables, they pick up all kinds of harmful microbes you wouldn't expect. Bacteria from your mouth can also multiply to dangerous levels inside of them and their damp, dark interiors can harbor mold growth.
Cleaning your water bottle with a brush and antibacterial soap after every use will keep germs in check and odors at bay.
Where germs thrive in your water bottle
- The interior. The inside walls and bottom of your water bottle can develop a film of bacteria without daily cleaning. Old plastic bottles can also have microscopic cracks in them where germs can hide out.
- The threads. The area where the top screws onto the mouth of your water bottle can accumulate germs and beverage residue.
- The straw. Many people disregard cleaning the thick straws that some water bottles use, making them havens for bacteria.
- The cap. Caps with drink holes or retractable spouts have a lot of surface area and tight spaces where germs and debris can build up. Even if your bottle has a basic cap that you don't put your mouth on, it still regularly gets exposed to the outside world and the germs that come with it.
Bottle brush types
- Nylon brushes are the most common type of bottle brush. They have nylon bristles that are either threaded through a metal wire or fused into a plastic stem. Their bristles can be coarse or soft, depending on the brush you choose.
- Silicone brushes are pricier than nylon ones. They are easier to clean and sterilize, thanks to their smooth surfaces free of nooks and crannies. Unlike nylon brushes, silicone ones carry no risk of scratching or removing paint from your bottle.
- Straw brushes are thin and narrow. They're made to fit into water bottle straws to clean their interiors but they can also be used to scrub threads, caps and spouts.
- Foam brushes aren't the best for cleaning, as their sponges can hang on to microbes and odors. However, if you're especially concerned about scratches they're still ok to use as long as you disinfect them between washes.
