So the other day I was driving behind my work and I drove through what appeared to be water, long behold it was cooking grease from the mex. food rest. down the way. It definently sprayed all over my doors and low fender )front and back) Now, its is caked on my car, looks awesome by the way. Anyway, how do I get it off, I've tried dish soap and that didn't work. Any suggestions before I go out and buy somthing. Please help. Thanx guys!
