Someone gave me some white scrub pads made by Scotch Brite that he uses to remove bugs from the front of cars when detailing. Doesn’t scratch the paint at all, and removes the bugs. I tried it on a test pane to see if it would scratch, and it doesn’t at all. No scratch, no swirl, no problem. I think they run about $30 for a box of 20. Part of my kit now.
