Product Description
EVAPO-RUST™ works through selective chelation. This is a process in which a large synthetic molecule forms a bond with metals and holds them in solution. Most chelating agents bind many different metals. The active ingredient in EVAPO-RUST™ bonds to iron exclusively. It can remove iron from iron oxide but is too weak to remove iron from steel where the iron is held much more strongly. Once the chelating agent has removed the iron, a sulfur bearing organic molecule pulls the iron away from the chelator and forms a ferric sulfate complex which remains water soluble. This frees the chelating agent to remove more iron from rust.
Evapo-Rust is highly recommended by the NRA Gunsmithing School and will remove blueing, browning, zinc phosphate, zinc plating and cadmium plating in approximately 30 minutes. It will not harm solder points or lead and preps the surface for refinishing like no other product.
