This is pretty crazy but Soft Scrub really saved my ***....... well my paint anyway. I was staining my fence few weeks ago and I moved my cars out away from the fence but, apparently, not far enough. A slight breeze picked up the stain from the paint gun and deposited it on the front end of two of my cars. By the time I realized it, it was already dry.
I got out my Porter Cable and tried 3M compound and Griot's machine polish. Neither one was taking it off. It was baked on pretty good. My wife suggested Soft Scrub but I was very reluctant to use it on the paint. She tried on the windshield and it took the stain right off. So, I put a little on an orange pad and put the polisher on high speed. It took the stain off without scratching the paint!! I followed up with 3M compund and swirl mark remover and the paint looks perfect.
Now, I'm not advocating using Soft Scrub instead of car care products but if you're up the creek like I was and ready to go to an auto body shop to have them take something as stubborn as wood stain off your paint, you may want to try a small area to see how it works. This stuff saved me few hundred bucks I'm sure.
