I have polished damaged CDs with jewelers polishing compounds of several types and high speed spinning buffs. On a CD that has seen a lot of abuse, it will remove 90% of the scratches, but the really deep gouges will resist being removed completely. I have also found that even though some CDs that look bad will play well, seemingly insignifcant scratches near the table of contents can render an otherwise good cd useless, and sometimes polishing won't fix it.
CD Repair?
I've seen several companies advertising CD repair by polishing out scratches. Here's a couple of examples: www.wefixcds.com & www.auraltech.com.
Has anyone had any CDs repaired? Successful? Worth the cost? Thanks!
