Letting
wet towels sit around on the floor or allowing them to sit in a ball on the edge of the sink is only going to breed gross things.
Hanging them up allows air to circulate, which causes them to dry faster.Ever forget to hang up a
wet towel only to find it invaded by fuzzy green mold or mildew? Damp
towels make the perfect environment for mold to grow especially when
left in a dark location for extended periods of time.
