Re: pool acid
I've used the process in the Caswell manual to strip chrome off metal with good results. (Sulfuric acid and water solution along with current). I have never tried the process with aluminum tho.... If it is a valuable part I think I would use acid only as a last resort. That shit can be dangerous, too. Will blasting not take the rest of the chrome off? That would be the simplest and safest way.......
