Thread: Dirty suppressor effect accuracy?

I have a 22 mag DPT suppressor that I use on both my 22lr and my 17hmr, I must have put 1000+? shots (mostly 22lr) through it and haven't cleaned it at all.

Does anyone know if it being dirty is likely to effect performance in any way?
It still works great with subs but based on how filthy my action gets with a few hundred 22 rounds I wouldn't like to think how dirty the suppressor is.
I can't really be bothered to unscrew it all, and it probably wont unscrew anyway, so if it does need cleaning what the best way to do it?
