Are you sure you're talking about this stuff because it is not phosphoric acid-based like most of the rust destroyers/converters out there. It is harmless to everything I've come across, other than rust.

I've been playing with stuff for 5 years now and it does not affect anything other than rusted steel and cast iron. In fact I've used it to clean the surface rust off of chrome plated trim parts and cad plated electrical components with amazing results and with no harm to the plated surfaces.

I had it strip the plating off a survivor 29295 diverter valve and eat through the aluminum body of an original 40669 AC fuel pump. I saved both parts and can provide photos. It was indeed Safest Rust Remover. I've been using the stuff for years. Pretty amazing stuff.

What kind of time frame did it take to do that? How long were the parts soaking in it?

The diverter valve was overnight. The fuel pump was definitely weeks. I forgot it in the solution. Still, I was absolutely amazed at the deterioration of the aluminum.

Just a heads up for everyone using the stuff. I still use it to this day but am much more cautious. Overall, an awesome product. Customer service sucks, however. Never returned multiple messages inquiring on the potential problems with plated and aluminum parts.

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 &quot;growing&quot; 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!

Playing amateur chemist here, could it be that if the solution has absorbed so much iron from the derusting process, when you place a dissimilar metal like aluminum in it, it could cause an electrolytic action that eventually deteriorates the aluminum?

Steve,
I think that an absorption of more iron oxide (it doesn't absorb iron) into the liquid would just slow down anything it could do. I don't know the chemical composition of this liquid, but it just seems to absorb oxides.

In this case I have to disagree as here is the evidence of it doing exactly that, shrinking bolts.
I placed an original bolt alongside to show how much they shrank. It ate the flanges and the threads equally.

If only we could somehow reverse the process so that when you pour this stuff on a rusty quarter panel, it adds metal and &quot;heals&quot; the holes.
