Re: Need engine detailing help
I was thinking CLR myself...try it in a small inconspicuous area and see what it does.
Simple Green may be a good idea also - but I've noticed it can 'spot' if the aluminum on the engine is hot (which wont be the case in your scenario...but I'm not sure what it does when the engine is cold).
A lot of the cars at Bonham had a ton of aluminum oxidization on them...
