Q12 Rust Remover, 200ml, 030054, Q20.

If you're looking for an easy to use, but highly effective rust remover, then look no further than Q12, a rust-busting solution that's been around since 1967! Thanks to its formulated mixture of hydrochloric- and phosphoric acid, this jelly-like solution works by converting iron oxide (i.e. rust) into iron phosphate, which can then be washed off with soap and water. Best applied with an old toothbrush or pain brush, Q12 can be poured, dipped or painted directly onto the rusted area.
