On CD's I have use eye glass cleaner with la lens cleaner cloth probably in
some cases more effective that soap & water. The abrasive or polishing concept
sounds like a fine idea. Roger

I have found that smearing washing-up liquid on a cd and rinsing in warm
water often removes small 'unseen' marks which can prevent a disc from
initially being read. This does not remove scratches but I have found that it
does help in a lot of cases. For deeper scratches, I would guess jewelers rouge
or plastic polishing compound applied gently on a polishing mop would work
quite well.
With reference to longevity last week: in 100 years, no one will know what a
CD is other than a shiny plastic disc. A vinyl record will show as a disk with
grooves. People will soon discover that by inserting a pin in a piece of paper,
resting the pin on the disc and rotating the disc, sound will emanate. Ideal
rotational speed would be easy to guess from the sounds. Similarly with film,
it will be something which is easily deciphered. Magnetic media or CDs, with
all the different formats, will be a challenge to understand.
