Rubber gaskets are still being used on many vehicles, especially heavy construction equipment. Cleaning these gaskets has always been a problem but Equalizer has solved this with the rubber gasket cleaner. To use the gasket cleaner, place the blade in the gasket and pull it toward you. The blade is sharpened on the end and on both sides so it will clean glass and old sealant out of the gasket with one easy pulling motion. The unique design of the RGC751 keeps your hands clear of the glass.
