Some of my tools have acquired a light patina of rust and corrosion over the years. As an example, here are my Stew-Mac nut and saddle vise and my little blue yard sale ($1!) vise. I've been meaning to get around to cleaning them up for some time.
I finally did just that. They weren't too bad to start with, but the results are noticeable.
The Rust Free spray has some sort of acid in it. It smells pretty potent, so I wound up using a respirator while I sprayed it.
The cleaned side is on the left. It makes the rusted side look bad, huh?
I also did the post and all the other metal surfaces.
This is fun! Now I'll pay attention and see how long they stay this way. The T-9 is supposed to be good for a few months. I don't use the press a whole lot, and it's dry in The Dungeon. I bet this clean surface lasts a while.
