"I literally had to put the tip of the pressure washer right up to the clumps to break it free. Rediculous."
Helps if you don't bake it on for 3 days before you try to wash it off.
Yeah, I know, I should have went straight to the cleaner, but I didn't, I drove around for about 40 minutes and then washed it off. Its so dry out here (except for in that mud hole, go figure) it hardens almost immediately.
