I don't know why, but for the last month or so our towels have smelled awful after they get wet. We were washing them in fragrance free detergent for the last few years and I thought maybe it wasn't strong enough, so I've started to wash them with Tide in hot water and they smell ok before we use them, then as soon as they get wet they smell musty. Does anyone know how to get a musty odor out of towels? I'm at the point where I'm considering tossing them out and buying new ones. Musty is being kind, these towels wreak like they haven't been washed for months after only one use.
