Household use of heat guns is common. Heat guns and lighter weight hair driers are sometimes used to remove paint splashes and wallpapers. Heat guns are also used to make plastics such as PVC piping pliable for the purposes of bending, to soften wax and adhesives such as that used in electronics, and to thaw out frozen copper pipes. There are also heat gun form factors friendly for food purposes such as melting hard candies, searing meats, or to start a charcoal fire or grill. Heat guns are sometimes used to upholster furniture and repair leather and vinyl goods.
