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.

I recently purchased this pressure washer from Lowe's for $99.
https://www.lowes.com/pd/Greenworks-1-600-PSI-1-2-GPM-Cold-Water-Electric-Pressure-Washer/50353388

It provides a spinning tip as well as two standard tips, and a quart
container to hold degrease/soap as you spray.

Using a cleaning product named "Greased Lightening", I have degreased
and cleaned several cars in the driveway. For the money, it's hard to
beat.

I'm going to weigh in here.  we had one of those electric washers, and it 
really didn't do the job.  1600 psi is nothing.  got rid of it

if you want to use it for anything else, forget it.  I upgraded to a 7 hp 
engine gas powered pressure washer.  with that, you can do the job!
