Use RustFree™ to quickly remove rust, corrosion and stains from virtually any surface, including: steel, cast iron, stainless, fiberglass, chrome, tile, porcelain, vinyl, cloth and more. Use Boeshield T-9® after cleaning with RustFree™ to protect bare metal surfaces.
Directions. For light rust on steel or cast iron, spray RustFree™ on a rag and wipe surface. Do not spray directly on surface, as it may cause spotting. For heavy rust, spray directly on rusted surface and scrub with Scotch-Brite™ pad. Wipe off and repeat if necessary. RustFree™ works best above 70° F.
CAUTION! RustFree™ is acidic and should be used with care.
Test on hidden area before use.
