I use two carbon fiber brushes; first brush is rolled quickly for one revolution of the LP to pick up the majority of any loose dust. The second brush is rolled slowly for a couple of revolutions of the LP. Then I swipe the brushes against each other several times to clear off the dust. Finally, I take one of the brushes and roll it for one revolution and then quickly sweep the brush off the LP at an angle. That takes care of any larger particles that weren't picked up by the first two passes.
After each play, I use one brush for a quick touch up and clean it off using the other brush.
I removed the handles from my brushes and grip the brush directly, which seems to help with static problems. I store both brushes in a small wooden box to keep them from collecting dust.
Are the brushes effective? Not for cleaning; that requires a vacuum RCM of some sort. But to sweep off surface dust I think they're better than nothing.
Regards,
Tom
