I clean every LP with my RCM and use anti-static sleeves and still suffer from static build-up. I do find that once on the platter and I've done a quick glide over with the carbon fibre brush (I put my index finger from other hand on the spindle) it does the job, although it does build up again as then when I take it off the felt mat comes with it! I don't seem to suffer from static type ticks/clicks during playback so I just get on with it. No idea if touching the spindle is earthing or not but it does usually give off a few spark-like sounds through the speakers most times. I must be charged up or something!
