I just moved into a new apartment and have been using the washing machine in the basement. I noticed that when my clothes are washed, if they are still damp, they smell like sweat. However, the bigger problem is that my towels smell OK when they are clean and dry, but after one use, they begin to smell really bad, I think it's mildew. The basement is not too damp, so I don't think it's that. What can be the cause?? It's driving me insane.
