What items should I never dry in this 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. Do not place items exposed to cooking oils in the dryer, and do not use heat to dry articles containing foam rubber or similarly textured rubber-like materials. (Page 3)
