I assume you've grounded your TT bearing and tonearm.
My record pre-playing ritual goes like this, also with a carbon fiber brush:
- dust platter at the start of the session
- dust underside of record (don't grind dirt into side B)
- zap record with Milty (it does eliminate static)
- clamp record, dust and touch a grounded piece of metal (tonearm) before lifting brush from record
Despite all this, a static-free record still builds up static by the end of play. I assume this is due to friction from the stylus. Yes, the tonearm is grounded, but apparently there's no path to ground from the record surface. There used to be a record-riding brush with metallic fibers and a ground wire, but I haven't seen one of those in years.
I zap the record with Milty again before it goes back in the sleeve, so it doesn't attract dust while sitting on the shelf.
