Best Answer

Most simple rust removers contain phosphoric acid, which dissolves flaky or granular rust, but does not seriously attack the parent steel. In fact it leaves a fine coating of iron phosphate which is a slight protective, and provides a good substrate for paint.

Scrub off as much of the flaky scale rust as possible - for this just wastefuly consumes the rust remover.
