8. Don’t hang wet towels on hooks, and don’t gather the shower curtain to one side.

After a shower, opening the shower curtain to dry yourself and hanging your damp towel on the hook almost feels automatic. Unfortunately, it’s a really unclean habit. Mould and bacteria can quickly grow in the crinkles of a wet towel and the folds of a collected shower curtain, respectively. For this reason, it is preferable to let your damp towels dry unrolled and to spread out your shower curtain until it is completely dry.
