FWIW, you will never get suppressor bafffles spotless when trying to remove lead deposits. The loose crap can be removed by some well placed center fire rounds down range.
I contacted YHM to ask if it was OK to shoot "dirty" .22LR ammo through one of thier sealed Phantom LT .30 cal suppressors and if so, how they recommend cleaning it. This was thier response

"Yes. You may go all the way down to .17 caliber if you wish. The suppressor works excellent on both. Recommended cleaning intervals is after 1000-1500 rounds have been fired through the suppressor regardless of the caliber being shot through the suppressor. To clean soak the entire suppressor in a bucket of mineral spirits overnight. Remove the next morning and shake the suppressor out, then blow it out with some compressed air. Then a light coat of gun oil can be applied to the outside of the suppressor and wiped off. This is all that need be done to clean it."
