Having recently started purchasing some old records from my youth I find myself in a very similar predicament. Although I clean all these with a GD and a manual wipe and rinse I still get the accumulation of dust bunnies on the stylus. Since my cartridge uses a fine line stylus I have come of the opinion that no matter what cleaning system one uses deeply embedded fine dust remains in the deepest recesses of the groove.If you properly and thoroughly clean a record, there won't be any dust remaining in the grooves. I use an ultrasonic cleaner and I only rarely clean my stylus. Even then, there's no visible dust - I just do it as a precaution.
