We once rented and used a commercial duty heated pressure washer to clean a
semi truck, tractor chassis and the big diesel engine. It removed everything
but the paint, although it did blast off loose paint flakes. That hot,
water-soluble degreaser, under pressure, really did the job. Then we hosed it
down with fresh water to remove any degreaser residue, blew out the excess
water with compressed air and let it sit until it was dry. Brushes and scrapers
helped too where the grime was really thick.

In my experience any media that will not strip paint, ie, crushed walnut
shells, plastic bead blasting, etc. will simply bounce off of grease and/or old
undercoating which is ineffective and messy. Even aggressive stuff like Black
Diamond will have a tendency to do the same, and will certainly eat paint when
it gets through. If your frame is immovable and you prefer to stay in the
garage, Kano Laboratories makes a superior degreaser that can be purchased by
the gallon. These are the same folks that make AeroKroil, the best penetrant
I've found, ever. Have your tarp or drip pans ready and brush away. I've used
old wooden paint paddles and plastic bondo spreaders for removal. It takes
time, but may fit your application.
