Hi guys im new here so take it easy on me. I got these stains on my wheels and wondering if sanding is the only way to remove the stain ? I've tried polishing and it looks like the wheel cleaner ate thru the clear coat. The wheels are a polished lip but not sure why type of clear coat if any is on them. It apprears the wheel cleaner sat too long and messed up the wheel. Any help is appreciated
