However so subtle to the naked eye they may be, the tiny scratches it leaves behind can be detrimental to bushings over time. Friction rubbing against the abrasive surface, (though it may seem smooth), can dramatically reduce the life of the felt after millions of note playing cycles. These parts should be polished with an appropriate compound/buffed or better if possible replaced. Hope this doesn't sound like a criticism, it's not. Just fact we should all be aware of.
