^yes they are aluminum. Black anodized
It wasnt the eagle one cleaner. Ive used it before without problems on the calipers and my painted wheels. It was whatever the car wash guy had. It was a purple liquid and he said "acid" but I didnt put 2 and 2 together until it was too late
Sorry dude. That sucks. Maybe there is some recourse.
I think it can sometimes be polished out of aluminum but I have a feeling that polish might damage the anodizing.
I did find this on an anodized aluminum restoration page:
For heavily oxidized or pitted aluminum, START HERE and use Heavy Duty Cleaning Steps. If the aluminum is just faded, these steps can be skipped. Make sure that the surface is clean before application of the coating.
* Make up a paste (thin) with a "No-scratch" cleanser like BonAmi and water.
* Use an approved scrubber pad. A blue or white ScotchBrite pad works well. Synthetic Steel Wool pads by 3M work great.
* Rinse the aluminum with water. Cleaners should be applied to a wet surface.
* Dip the scrubber into the mixed no scratch cleanser and apply to the window extrusion.
* Scrub gently to remove oxidation, dirt and any mold etc.
* Rinse well, Do not let the cleansers dry on the surface, it will be more difficult to remove.
