Whatever you do, don=E2=80=99t use a pressure washer in the garage!   I hun=
g tarps and covered everything with plastic sheets, and still had to deal w=
ith pretty much everything in the garage being wet.    I was disappointed i=
n the results too =E2=80=93 I suppose it did remove a lot of dust and soil =
type dirt, but anything greasy would need a detergent or heat to get rid of=
 it.   I used a fairly powerful home-type pressure washer =E2=80=93 about 3=
000 psi and 3gpm.   I hoped that a lot of the looser underseal would come o=
ff, but only the stuff I could peel off by hand was moved.  =20

I did read good things about using dry ice as blast media, but it appears t=
o need a special blaster, and I couldn=E2=80=99t even find one for rent in =
Houston.  From what I saw, it would remove dirt only, or turn up to higher =
pressure and it would remove underseal.   The dry ice would then melt and l=
eave the underside of the car clean and dry with only the removed dirt/unde=
rseal on the ground.   I suspect this would get very expensive unless you h=
ad a source of cheap dry ice.

Cheers

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 everyth=
ing 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 exce=
ss water with compressed air and let it sit until it was dry. Brushes and s=
crapers helped too where the grime was really thick.=20

Sujit

In my experience any media that will not strip paint, ie, crushed walnut sh=
ells, plastic bead blasting, etc. will simply bounce off of grease and/or o=
ld 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 s=
tay in the garage, Kano Laboratories makes a superior degreaser that can be=
 purchased by the gallon.  These are the same folks that make AeroKroil, th=
e best penetrant I've found, ever.  Have your tarp or drip pans ready and b=
rush away.  I've used old wooden paint paddles and plastic bondo spreaders =
for removal.  It takes time, but may fit your application.
