Default Re: Rust removal from steel component on the cheap.

I agree with Kalee: Oxalic acid, sold here as a concrete and patio cleaner in a granular form, is very cheap and superb. It needs no heating and the steel item can be left in the solution indefinitely without ill effect.
I keep the solution in old 2L plastic milk bottles, and pour it into whatever plastic container best suits the shape of the item to be cleaned. It can be reused many times until it loses its potency.
The rust disappears completely leaving a matt grey surface.
It hurts like heck in a cut !!
