I used to offer injector cleaning but always discouraged it as a short-term fix at best. Problem is that new ones cost >$700/set so I can understand why folks want to try cleaning them.
You can take them apart and if you do will see why they are not worth refurbishing. The spring is rusty and worn out, there is all kinds of crap in the screens, which are also rusty, and buildup on the pintle. I sonicated the ones I cleaned for folks with the pintle held open. They did work better but nothing comes close to new.
Now I just verify cracking pressure and spray pattern. If they fail they hit the trash can.
