The first 2 times, I used Purple Power full strength. The 3rd time, I used Go Jo hand cleaner (just the regular old white product that has been around forever). I wipe it on by hand and also by a parts washing brush. I let it penetrate in, plus agitate it with the brush and scuff pads. I'll reapply to keep it wet. Then I hit it with the steam cleaner. As you can see, there are small areas where the undercoating remains. I don't know how nuts I'll get, as the car is just a nice driver.

Well done Tim! I recently did an undercarriage and used some undercarriage products made by the Chemical guys. It’s kind of product you can put on after you clean.
