Review on 🔧 Evapo-Rust ER004 Super Safe Rust Remover – 32 oz., Non-Toxic Rust Remover for Automotive Parts, Hardware, Antiques, Rust Dissolvers, and Chemicals by Amanda Rodriguez

I used this on an old two bladed ax head that I am restoring and it removed most of the rust leaving only deeper holes. Turn this head into a guardian with a grinder and some sanding. What struck me was the effect on the hardened ends of the blades. They both turned darker than the softer center and the finger hole, which was not heat treated. Careful. A good thing. Saved it for later and plan to use it on some old hammer heads and ball stop hammer heads soon.
