i have a an odd cleanup problem. I drove around the back of a building on a shopping mall parking lot. There was a puddle across the lane, I made the classical error of making an assumption. I assumed it was water. It was in fact liquid cooking grease (shortening of some sort) and my tires, picked up and tossed a liberal amount along the driver's side bottom of the rock rails, the lower surface of the body, and the rear left fender. The fenders are the stock plastic fenders, quite faded these days. The irony was that I had just received a restoration kit and was planning to make them look all black and neat that weekend. In any case, the grease came off any exposed metal readily. But the fenders now, they are a different tale. I scrubbed them thoroughly using Dawn, which is a standard cleanup method for oil in HAZWOP operations. So far, no joy. Any experience or suggestions would be appreciated.
