18. Do not leave your bath sponge in the shower.

If you like using a bath sponge, washcloth, or loofah when you shower, make sure to store it properly after using it. Because bacteria flourish in warm, moist places, leaving your bath sponge in your shower may promote their growth. Research has even found that the average loofah may be host to dangerous bacteria like E. coli. Using a bacteria-ridden one can cause infection to your skin, especially if you use it after shaving. To avoid this from happening, keep your bath accessories out of your shower and store them in a dry place when not in use.
