What fabrics or items should never be dried in the dryer?

Do not dry articles that have been exposed to gasoline, dry-cleaning solvents, or other flammable substances, as these vapors could ignite or explode. Items containing foam rubber or similarly textured rubber-like materials should not be dried with heat, and articles contaminated with cooking oils should also never be placed in the dryer as they can cause a chemical reaction and fire.
