Stylus cleaner

This looks like it should do the trick.

I have a similar carbon fiber stylus brush that I have used or years. I think it is the old Discwasher brand, but not even sure. Extra bonus is its all wood, encloses into a case to keep clean, all one piece and has magnifying mirror on the rear side for inspecting stylus condition when needed. Perfect if you can find or make something like this still these days.

Like This if any still around.

magic eraser does not sound like a good idea off the cuff, but have never tried. Potential to damage stylus? Does it really work to dip? No residue from the ME itself?

My wife loves them and uses them for everything though.
