HDX is a non-flammable, fast-acting, heavy-duty solvent for cleaning and degreasing metal parts and equipment. It quickly removes oil, grease, wax, dirt, moisture, tar, brake fluid and other contaminants. HDX is fast evaporating, non-conductive and does not leave a residue. HDX is ideal for applications where flammability is a potential problem. NSF K1 registration # 059809: (aerosol); # 059810: (bulk).
