  • Cleaning Rust Off of Tools Without Harsh Chemicals

    I've been using this method (along with electrolysis) for many years, and have the following comments:A) Adding salt *does* speed up the reaction, but also tends to make the solution eat the base metal- you need to watch it closer.B) If you reuse the solution, as I do, it gets stronger due to evaporation, so older solution needs to be monitored more closely, especially when salt has been added.C) This method tends to eat platings, so test a plated sample if available.D) In some cases with brand new vinegar, the reaction can take a few days to start.E) I've never, ever gotten a chemical burn or irritation from contact with the solution, even when it's old, salty and much stronger, but the black residue can really stain your hands.
