Your favorite carbon fiber cleaning brush ...?

I honestly don't use one. I keep my records clean with a Degritter II, using just DW mostly. I also clean my stylus religiously, with Lyra SPT, before each listening session, and with a dry brush after every record. I have a Roksan two-stage micro-fiber brush. It works better than anything else I have tried, but the truth of the matter is they all just rearrange the dust on the disc more than anything, and don't really remove much from the disc. I guess YMMV depending on climate/environment. I am in an HVAC managed listening room.
