I have no clue how the bubble wrap can leave permanent marks on the piano finish of the speakers. Since you have tried various methods without any degrees of success, I would stop trying. You won't know as you may do more harm than good. As some posters have suggested, it may be wise to contact a piano store that refurbishes/reconditions used pianos. They would have a better idea on how to solve your problem. Normally they would grind of visible scratches and respray using special paint. If you do not want all this hassle you might want to contact the seller.
HELP...Bubble Wrap Marks in PIANO BLACK Speakers??
I just purchased a pair of Piano Black speakers here on Audiogon. I received them today (9/12/06) nicely packed and carefully wrapped with bubble wrap. As I unpacked & unraveled the bubble wrap from each speaker, I noticed the bubble wrap left round shaped dot marks on the Piano Black finish of each speaker. It is not something that can be felt with the finger, so I thought it would wash off easily.
I tried cleaning with water, Windex & Orange BLAST Auto/Shop degreaser. Nothing worked. Then I tried Liquid Glass auto polish and Zymol cleaner wax. Still, I can't remove the bubble wrap markings. I even tried 70% rubbing alcohol in a tiny back corner. That did not work either.
I'm getting a bit nervous now, since these speakers were stored several months in this wrapping and they're all covered with the marks like leopard spots. I don't know if the marks will come out now, or how the Seller will respond to this. He is aware of the marks, but not that I can't get them out. I'd really like to remove the marks and to keep the speakers. Does anyone have suggestions for a cleaner for this?
