hi people. I've had my pioneer PDP507 for almost a year now and have been using the "special" cloth that came with it to clean the piano black finish but have noticed lately that its causing light surface scratches. is there anything out there to fix this? The black finish attracts alot of dust in my room and i'm having to clean in weekly, is there other products and cloths i can use to clean it? also what should i use to wipe the screen? Advice would be appreciated.
