I like 3M Scotch-Brite heavy duty scour pads. They are non conductive and clean well.

Be sure to lift the brushes off the rings before you clean them, so no grit gets imbedded in them. After cleaning, wipe the rings off with a clean white cloth before re-installing the brushes.

I use fine Scotch Brite then buff them with crocus cloth. After that a quick shot of electromotive spray to remove any film on them
Remove the all rotten apples out of your basket of life and toss them in the trash where they belong.

As an apprentice I was taught never to use carborundum paper on slip rings or commutator bars, but fine sand paper. Apparently the carborundum imbeds itself in the copper and carries on doing its job after you think it's all been cleaned off.

I work on locomotives for a living and when we have a rough slip ring we put a stone under one brush and start the unit up. It works great. There are 3 different grits and the final one is white and almost looks like talcum powder. But at idle these are only turning 1-200 rpm. I donít know how well this would work with a small generator??

I have cleaned up many by running the starter while holding a stone to them while running.
