I have stained the aluminum inner fenders with splashed hot anti-freeze [50% if it matters] and now have permanent stains to live with.
If anyone has found success removing such stains [almost looks "bleached"] I would greatly appreciate the advice, the product and the method to do so. I've tried every compound, polish, spray cleaner and even bronze wool to no avail.
I can't use wet-or-dry with WD-40 due to the difficult locations to reach and that's with the motor currently out of the car!
Help and thanks!
