This cleaner wax is the ONLY one that takes off the diesel residue from exhaust. And although Colonite has many products the 920 is one that cleans off the yachts mustache. Too, it is easy to use. Like other cleaner waxes you wipe it on and then wait a minute or two and buff it off. The mustache created from running the diesel will be fully removed and your hull will look brand spanking new.
I've tried other products, regular cleaner waxes, Flitz, Acetone, Mineral Spirit, Alcohol (not the medicinal one) and anything else people have suggested. While some appear to remove a small amount of the diesel mustache none do it as well or as fully as the Colonite. And like most all of the A products I've listed I will be purchasing this again.
