Workshop Hero Metal Rescue Rust Treatment | MC TESTED

A non-toxic, water-based treatment for rust removal.

From acid baths to sand blasting, there are lots of ways to clean out a corroded gas tank. Add another, better method to the list. Metal Rescue from Workshop Hero is simpler, easier, and safer than any other process I’ve tried (and I’ve tried them all). Metal Rescue is a non-toxic, water-based mixture, so it won’t ravage your skin or damage painted, plastic, or rubber parts. And it works. Like magic.

I’ve used Metal Rescue to return a half-dozen old gas tanks to service, clean up corroded tools, and restore rusty parts. So how does it work? “Chelation,” says Workshop Hero Vice President Dave Yancho. “The chelation agents in the fluid have a stronger affinity to rust than the underlying metal does, so it pulls rust off the surface like a magnet.” Essentially, rust likes Metal Rescue more than it likes the metal it was born on.

Metal Rescue will penetrate dirt and oil, but that reduces the product’s life. For the best results, clean grease and other grime off the part then submerge it in Metal Rescue (or in the case of a gas tank, pour the mixture into the tank). Just a couple hours in a Metal Rescue bath is enough to leave lightly rusted pieces looking fresh, and you can reuse the solution until it turns black (it darkens with use) or becomes ineffective.

There are numerous ways to get rid of rust, but you only really need to know about this one. Metal Rescue is available in 1-gallon jugs for $25 and 5-gallon pails for $100, and Workshop Hero says each gallon of fluid will remove up to a half pound of rust.
