Rust converters are best used for heavily rusted metal that can’t be removed otherwise. A rust converter that includes the chemical phosphoric acid also prevents rust from returning but requires a respirator mask to use and subsequent curing. Note that rust must be present for rust converters to work since this activates the chemicals in the product to turn the rust into iron phosphate. Some products are safe to apply on paint, while others will cause the paint to bubble. We have covered some paint-safe converters but suggest reading the instructions if you’re unsure. When you have a large amount of heavily rusted items to deal with, Corroseal’s rust converter can cover it all with a paintable surface that protects against future rust formation.

Acidic solutions dissolve rust, which is one reason that so many rust removers use acid-based formulas. Tannic acid is a common ingredient in rust removers, which converts the rust into another form that doesn’t spread or further corrode the metal. Other solutions bind with the dissolved rust particles and remove them when the entire solution is rinsed or wiped away.Workshop Essentials: Popular Mechanics Tool Awards 2023 • Best Shop Vacs for Cleaning Up Your Garage • Best Power Sanders for Your Shop Form and Application The fluid didn’t seem to penetrate and bond into the metal, appearing to film a skin over the top of the rust instead.
