The previous owner of my car got quite a bit of wax in crevices between body panels and it's now dried and pretty ugly. I'd like to safely remove it, but I'm not sure what product will dissolve the old wax and what is the best way to get into the cracks/crevices containing the dried wax? Also, what product would you suggest for removing wax from vinyl/plastic surfaces on the car's exterior mouldings, etc.?
