any ideas on what to clean an EGR valve with?

What's a good solvent for all the gunk? Mineral spirits, kerosene, gas, nathpa, paint thinner, turpintine?

Mine is completely clogged. I picked a lot of crap out of it and got it opened up a little. But the gunk inside is very resilient.

I've tried soaking on degreaser, carb cleaner spray, solovents. But whatever it is that goes through the valve has built up real good and solid.
