Well now I know there are auto forums out there but since I am familiar with the MacRumors community I thought I would post here first. Anyways I have just done a lot of body work on my truck including repainting and finally have all the repairs, painting, and polishing finished. But after using both rubbing compound and polishing compound there is some left over residue. Specifically there is dried on compound left on the heavily textured plastic surfaces and in the crevices between molding and body panels. I can not seem to find a way to remove this white residue. It is impossible to get a towel or polishing pad into the fine crevices to remove it and and toothbrush seems to have very little affect. What would be a good cleaning product be to remove the caked on compound. I am a little leary of scrubbing with the toothbrush because I do not want to scratch the finish after spending 5 or 6 weekends doing body work. I should note that I live in Georgia and there is currently a drought so outdoor water use is prohibited. I have to limit my cleaning to liquid I can stick in a bucket or go to a car wash that I can clean the car myself at using a pressure washer. I haven't bothered with the car wash since it is the rainy season and washing the car when it will likely rain in a day or two seems a waste.
