How to rapidly remove rust stains from paintwork

We've tested Benz Oxy Cleanze rust removal gel on household, commercial and marine painted surfaces with excellent results.

We encountered no undesirable bleaching or additional staining when used on various types of paint including exterior masonry paint, single-pack marine coatings, two-pack marine gloss and enamel.

We tested Oxy Cleanze rust removal gel on all these painted surfaces with excellent results before offering it for sale. That said, because the chemical formulations of paint are continually changing, always treat a small, inconspicuous test patch first.
