Yo dude, I think carbon brush is mostly for the odd time there is some obvious debris on the surface - I rarely use it. For day to day I use a Milty velvet brush, much less abrasive. You can also get goat hair brushes which are super soft. Have a browse.
By the way, I know its a long shot but I now have an Okki Nokki record cleaning machine, so if any of your records need a deep clean, you can post em to me and I will give them a proper vacuum clean, free of charge obviously! It's a great piece of kit, make records at least a grade better, I've bought some really old records from the 70s which are at least VG+ after a run through the machine.
