It is a pity that this means already makes almost a misnomer called rust protection and RUST. It converts neither the rust around (in the usual iron phosphate or tannin compounds) even after application, it protects against further rusting. BUT: this means is very well suited to remove rust. You just forget the processing instructions of for brush and drying time, so you can just throw in the rusty objects pure or slightly diluted liquid and rust is very well located. Price-performance is very good with this product. It may sound a bit strange: do not observe the Verabeitungshinweise, but probably the safety instructions!
