I find for dry cleaning, my Audioquest brush works great. I have the current model, but also have several older models and the Decca version that these were based on, plus many other ones. Just looked in my drawer and found at least a half a dozen different old brushes. Someone would come out with a new one, so I just had to try it.
I've used these type of brushes for almost all my 50+ year audiophile career and always thought they did a decent job...
