How do I clean the dryer drum interior if it gets stained?

Apply a liquid, nonflammable household cleaner to the stained area of the drum and rub with a soft cloth until the stain is removed. Then wipe the drum thoroughly with a damp cloth and tumble a load of clean cloths or towels to dry the drum. Note that garments with loose dyes such as denim blue jeans may discolor the drum interior, but these stains will not transfer to future loads.
