Are wet towels dangerous?

ALWAYS hang your towel up after you're done using it. Yes mold and bacteria love wet towels balled up on the ground whereas if you hang them up, they will dry quicker and have less time for bacteria to fester and smell funky. I use one to two towels a week. Sometimes in the winter it takes longer for the towel to dry so it gets funky smelling, faster but in the summer? one towel a week!
