Removes ingrained rust like nobody’s business! Tried it out on a black plastic toolbox that had been covered in iron filings then left in the rain. No amound of scrubbing made any difference until I tried this stuff and it came up like new! Have since used it on the wheels of my Alfa with great results. The included spray head wasn’t much cop so ended up using the excellent Valet Pro spray heads whick produce a finer mist and make the product go further.
