What items should never be placed in the dryer?

Do not dry articles that have been cleaned in, washed in, soaked in, or spotted with gasoline, dry-cleaning solvents, or other flammable or explosive substances, as they give off vapors that could ignite or explode. Items exposed to cooking oils should also not be placed in the dryer, as they may cause a chemical reaction that could cause a load to catch fire. Additionally, do not use heat to dry articles containing foam rubber or similarly textured rubber-like materials. (Page 3)
