Re: Rust remover - more amazing uses!
I've used it with very good results on AFB carbs when throttle shafts or choke shafts were stuck or rusted. It removed all the rust, freed up the shafts and there was no sign of any harm to the aluminum at all. It also seems to have an ability to remove aluminum oxide, judging by the cleaner surface of the AFB castings, but that doesn't mean it attacks aluminum. Since the primary chemical in it is H2O, leaving aluminum in it over time will cause the aluminum to oxidize. Then of course, the product removes the oxide. IF you play that senario out long enough, you'll wind up with a lot less aluminum because it's turned into oxide which is then removed by the product.
A lot of platings are the product of "growing" an oxide film on a part in a solution with other chemicals. Those platings (such as cad or zinc) may disolve in this product. Other platings, such as chrome, are depositions, purely created from the chemical bath its in. Those platings are not likely to be affected because they are not based on an oxidation process with the base metal to make them grow on the surface.
Put an original black oxide bolt in this stuff and it will come out bare metal. ....but it won't turn into a smaller sized bolt!
