If you use a dryer at the laundromat, definitely stop it on occasion as the others suggested! I used one when my dryer was broken a couple years ago and although I adjusted the heat setting to low heat, it destroyed the entire load. It was so hot, I`m surprised the clothes didn`t catch fire! Even a pair of jeans came out so wrinkled I was unable to iron out the wrinkles. A dry cleaners may do it for you. They have the same large dryers but keep them serviced properly so as not to ruin their customers` clothing.
