BARNACLE-X not only dissolves calcium- and silicone dioxide-based shells and exoskeletons, it also breaks down mineral accumulations and the bio-adhesives secreted by barnacles, mussels and limpets, so that those organisms can be more quickly and easily removed from vessel hulls and running gear. Removing rust from cars, trucks, boats, RVs, motorcycles and ATVsīARNACLEX is the only biofouling dissolver / remover whose chemistry targets the complete range of issues associated with both fouling organisms and the dissolved minerals contained in fresh, brackish and seawater.For this purpose we recommend neutralizing / rinsing the cleaned metal surface with Xtreme Clean™ and water and then either paint, or if you prefer a clean metal look, use CorrosionX®. PLEASE NOTE: Once rust has been removed, it is important to treat metal with some kind of protective coating so that the clean metal surface does not re-rust. Compatible with most vehicle paints, decals, wiring and hoses.Prepares metal surface for paint and increases lifespan of paint job.High potency formula, can be used indoors.NOT FOR USE on firearms, as Rust Remover will remove gun bluing. Effective for use on most painted surfaces for removal of surface rust. It is compatible with many surfaces and will not harm most glass, hoses, decals, plastic, rubber or vinyl and paints. When the rust is gone, the chemical transformation has occurred, and the surface is prepared for a protective coating such as paint. Begins working immediately to transform rust into a gray/black iron phosphate, which interrupts the rusting process. Eliminates rust from iron and steel without harmful fumes. Rust Remover is a breakthrough in the removal of unwanted rust.
