First thing I do is clean under the hood with an all purpose cleaner and shop rags. Then I use a cleaner wax(Only place I ever use a cleaner wax)Next I cover the wires as much as possilbe, computer box, and electrical components with plastic. Then I use elbow muscle lots of shop rags and all purpose cleaner. If need be I get some gunk for stubborn areas. I light rinse with a hose then my big secret for the shine is I use my Ultimate Dressing. That what brings it to life.
