Removing Old Rocksett from Barrel Threads

[Skyyr]

Hey guys...

Another potentially dumb question here, but I'm swapping out a Smith Vortex on my Noveske with an AAC Blackout Flash Hider. The Noveske was attached using Rocksett and, obviously, there's Rocksett left behind on the threads. I'm a perfectionist and I hate applying new Rocksett over the old, gummy left-behind stuff. Is there any way to remove it effectively? Or is it good to go as is?

Thanks!

Brush /scrub the old stuff off the threads with a wire brush. Blast any residue off with brake cleaner. You are ready to go.
