Default Removing Salt From Aluminum

IS THERE ANYONE WHO KNOWS HOW TO GET SALT OUT OF ALUMINUM, AND NOT BY JUST WASHING IT, LIKE SOME SORT OF SOLUTION THAT NEUTRALIZES IT, ANY IDEAS?

If you have a good auto paint supplies store they should have what you need-
Alumiprep (etch)
Alodine 1101 or 1201 after you have etched and rinsed thoroughly. (1101 is clear, 1201 gold tint alodine)
Dow, 3M, Henkel Surface Technologies are all mfg.s of these products. Same stuff we use in aviation for corrosion treatment of aluminum structures and parts. Follow the instructions on the containers carefully.
Muriatic can physically eat away at the grain structure of aluminum alloys, even when diluted greatly. Stick with the Mil-Spec stuff......

audacity is right. LIME AWAY is good for neutralizing salt on stainless. I can't remember if it works on aluminum as well.

i used to use lime away and a hard scrub brush...my driver phil would make fun of me...so he made a point o bring me a ultra soft brush, 1/2 gal of water with a cap of ma in it....the **** falls off!!! i felt like an ass!...after that we rinse everything and spray and whipe clean with royal purple spray. the inside hub on all of our props look better now that when they came out of the box.

it will burn like hell if you get it in a cut...and eat holes in your clothes...

We use muriatic acid all the time at work. If you use it, don't get it on any stainless steel, it will tarnish it, and the only way to remove the tarnish is to grind it off.

What about boiling out the innards of a procharger intercooler? What would you recommend to eat the salty crap out of them and THEN what would you recommend to run back thru them to kind of leave a protectant there (no more salt thru them, only fresh from now on).

bro...i have no idea what lies in that intercooler...or what coating(s) they may have used....i do know we flush with fresh water and dish soap does a damn good job on our engines...what does procharger say???

we have propblems in dyno testing with coolers...our water is hard on them....we now replace them at a given point no matter what.
