I soak them in common fuel injector cleaner for about three days. Yes the screens are removable, but they are easily damaged. I would do a visual check first, and then if you think they should be serviced completely have them serviced at a reputable injector servicing shop. letting the pintle side soak though should do a whole lot of good.

Elbow grease. A lot of it.
No seriously though when I do this job I spray brake clean into all the ports of the removed parts. It air dries. Since the color on the plenum and valve covers are so caked on from heat, using brake clean doesn't damage the surfaces as much as it normally would if you sprayed it on a painted surface. From there I clean the mating surfaces REALLY good, clean the EGR tube super good, clean up the PCV system (it's likely got residual oil that did not get burned off), and then reinstall.
