I bought a number of CDs from the public library clearance bin that
have smearlike scratches, ie. not deep. I will like to remove these
using BRASSO a metal polish. Can this be done and not affect the read
data? I use BRASSO to remove sawmarks (emery paper polished first) on
plexiglas.

Thanks in advance.

If the CDs play OK, leave them well alone. Most audio CD players handle
fairly bad scratches OK although your computer's CDRom might trip up.
Polishing can lead to concavities in the surface of the CD which may affect
the laser, only polish the scratch until the disc plays OK, go no further.
IOW, don't try to get the CD cosmetically perfect.

I's start with mild soap and water to just make sure that what you're
seeing isn't just dirt or grease.

If that doesn't work, I know that there is a small hand driven machine
you can buy for about $35 that will polish these. I know our video
rental place uses them, and sells them, too. This might be a
worthwhile investment if you have a lot of poor disks.

The brand MAY be Diskwasher.

Brasso will destroy the CD. Use toothpaste. Buff the scratched area
gently from the center outward, not radially. The disk will look very
polished in that area, but should work well.

I used Brasso and it worked fine. Even better use Jewellers Rouge and
water, this will give you a very fine finish. Or you could use talcum
powder and a little water. I found toothpaste too abrasive. If you use
Brasso, make a copy of the CD just in case but I have not had a CD fail that
I'd given the Brasso treatment.
