I have a metal slide which I am trying to restore, and I was wondering how I could remove the rust without the use of a chemical rust remover, priming, or painting (in order to retain the slide’s slippery nature).
Thanks in advance.
Rust will leave a rough surface, and chemical rust removers would only remove the rust, leaving a clean, but pitted surface.
About the only way to restore it to the original smoothness would be to sand the rust until you’re almost down to smooth metal using a medium grit sandpaper, moving to finer grades of sandpaper until you’re using about 300 grit or finer. If that’s not slick enough, use some rubbing compound and a polisher to bring it to a near mirror finish. Or just let the kids polish it by sliding down it a couple hundred times.
