Pour it out. Then Blow out with a air comp, rem oil it and drive on.
If it is really bad do it the soak process again.
That did not work for my HTG Aris. Neither did soaking it solvents or using a ultrasonic cleaner for hours. I could not get the cap to unscrew off the end of it even. Like it was welded on there.
Finally took it to my local gun shop where he had seen this happen before. After clamping the can in a well padded vice he heated the end with a propane torch for a few seconds and...presto! The cap unscrewed. Man! Was it ever carboned up! I had not cleaned it in years and had no clue that it was this bad. The baffles would not come out because of the carbon build up.
Finally out of desperation I put the can in my Thumler's Tumbler with the SS shot that I usually clean brass with. Big glop of Dawn, water, turn it on and waited. An hour later and the water was just black with carbon. Yea! Now I'm getting somewhere! I ran it for a 3 more hours and took out my brand new looking suppressor all clean and purty. Why did I not try this before I wondered? Next time I will make a point to take it apart and clean it more often so that I will not have to go through this rigamarole ever again.
