Run the dryer on low for 10 to 15 minutes to loosen the plastic from the drum. Scrape away the soft plastic with a plastic paint scraper or old credit card.
Dampen a soft cloth with non-acetone nail polish remover. Work the polish remover into the plastic residue to lift it from the metal.
Dampen a cotton swab with the nail polish remover and clear any holes clogged by the melted plastic.
Combine 1/2 tablespoon of liquid dish soap with 3 cups warm water and stir thoroughly.
Soak a soft cloth with the soapy water and wipe down the dryer’s metal drum. Dampen a separate soft cloth and use it to wipe away any remaining residue.
Keep the dryer door open and allow it to air dry completely.
