So I have about 80 rounds through my new varminter 4.0 and I was able to get 4 of the 8 baffles clean soaking in hoppes bore cleaner. 4 of them still have some stuck on them. I do not have an ultra sonic cleaner to try as I have seen some recommendations of that. I ordered some slip 2000 carbon remover that should be here today to try. Anyone else have any other good ideas for it? I have scrubber with a stiff nylon brush and been soaking for about 4 days now. Are people getting them close to clean or spotless. This is my first suppressor so I would appreciate any input. Thank you
