Now, normally, my engine is spotless, but it rained hard here last week, and I went around a curve in the road into a giant mud puddle. When I got out, I looked at the body, and there was no mud anywhere, so I thought I got off easy. Earlier this week, I popped the hood and there was dry mud (Georgia Red Clay) all over my precious engine bay. Does anyone know of somthing that will take that off, or am I just gonna have to get after it with a toothbrush?
