Thread: Oils on rusty metal

Does aplying oils on rusty metal witout 1st cleaning off the surface rust still prevents furthur rusting as long as the oil is there, or rusting can still continue inside?
Is there liquid or something that can wipe off rusts like magic

A surface coating of oil will slow down further rusting but will not stop it completely.

Nothing removes rust like magic. Depending on the metal, there are commercial rust removers available. Naval jelly (phosphoric acid in gel form) is a good generic rust remover, but you must rub vigorously.

It's called etching acid. Go to a panel & paint shop?
