Re: Rust remover - more amazing uses!
 

I've used it to remove zinc plate. Yes, be careful with zinc and aluminum parts. -You can do controlled/short dips (multiple if necessary) followed by a good rinse with water and wipe-down with a clean towel to prevent over-soaking and keeping a brighter finish.

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.

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 &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?

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.

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.

Rick,
I don't know what solution you soaked those bolts in, but it sure wasn't the liquid we're discussing here! [img]<<GRAEMLIN_URL>>/scholar.gif[/img]

Verne,
Well I'm not going to try to prove it to you, but you're wrong, [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img] as I know what I had those bolts soaking in.
It most definitely was in Safest Rust Remover.
