No this isnt a personal hygiene question. I want to clean up the underside of my 80 so I dont look like a crawled out of the Le Brea tar pits everytime I go under the truck. I also think it will help me identify where exactly some of my leaks are coming from. Any tips on doing this? I tried the car wash but the water sort of bounce off the greased up parts. Any cleaners out there that i can spray and rinse that are strong enough to clean things up? What about some sort of media blasting? Is that safe to do on the underside?
