Now how aluminum got rust ion it, I dunno. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Are you sure it is not gas dripping or over flowing when hot? I use the Eagle brand of cast aluminum wheel cleaner, spray it on for 20 to 30 seconds and wash it off very thoroughly I've only had one intake take two doses of that stuff to get them spotless Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Any suggestions to clean it up without removing it? I've found that wd40 does a fantastic job on our old Corvette's Edelbrock intake manifold that has their so called chrome like "durabrite" finish. Might be worth a shot on a plain aluminum one. Soda blasting or very mild other blasting media works very well,,,but of course normally requires removal of unit.

Looks like someone changed the formula, you are right no more HF, not in Lime Away anymore either. They say there are no such thing as a stupid question.

Very nasty stuff. I delt with it in very concentrated form at my last job. We had a very strict handling program and our own emergency response unit that trained weekly incase of a spill or contamination problem. Photobucket sucks

I don't spend my time following cleaner formulations, but it is hard to believe that HF would have ever been in any household cleaners. Now CLR use to have phosphoric acid in it. It is unfortunate that it is gone from the formulation, as there really is no good reason for its removal (other than some EPA stuff most likely). I believe that phosphoric acid is the cleaning/oxidation removal agent of choice for aluminum.
