Thread: saving etching among rust

This is my first post so here it goes. I got a near wedge off ebay, it had a lot of rust among a large etching. I wanted to keep the etching so I tried a product I had laying around my work. I soaked the razor in a chemical from ZEP called Rust Eraser. 10 min. in the solution and 10 min. hand polished with brasso. The chemical was tough on the rust and left unoxidized material alone as far as i can tell. Give it a try
