Dan Ro, I have a couple buddies who work at auto detailing places and I have access to some pretty awesome car-safe acids. My wheels were not severely corroded but they were pretty bad. Used some cleaning acid they have called "Ninja" and it really cleaned it up.
If your looking into cleaning them up before you want to paint them in the spring we can meet up
Thanks. I will also ask the vender at work that I my cars to for the lot. We have a good working relationship.
