I have used Novus plastic polish successfully. You apply a coarse grade first and finish with the lightest one which leaves a polished surface. It can deal with most small scratches/abrasons.

this does look to be a good suggestion - I tried some auto polishes that I had around - even the fine cut didnt do much good on those. On the internet somewhere it said use the Brasso polish which too might be fine enough

The clever part about Novus is the three grades that you apply (for CD sctatches you probably only neeed to use the two lightest). Also the set of three smallest bottles is pretty cheap and will last for a long time.
Brasso is roughly the equivalent of Novus #2 in abrasion. However I seem to recall that Brasso contains something to inhibit tarnishing of the brass after cleaning. It certainly has a strong chemical smell (Novus is pretty neutral). I would be worried about cleaners that leave such residues as although the disc may seem fine immedialtely after cleaning there is a possibility that when you return to it weeks or months later it will be unplayable (remember, what was it, Armourguard ?). I have had similar experience with certain optical enhancers/cleaners.
NB: Given my strong recommendation,the usual disclaimers apply.
I saw they had a course grade and a fine grade but then the sort of generic "clean and shine" thing -
Which one is the most course grade actually? They seem to be sold in kits of those three very commonly
JaroTheWise
The Novus polishes are normally sold in kits of 3 as the idea is to start with the most coarse (#3). This will deal with deeper scratches but will leave small abrasions of its own. So you then polish these out with #2 and finish with #1. From my experience most CD scratches are pretty superficial and #2 followed by #1 may suffice. Obviusly there will be departures from this.Elbow grease is also required :-)

I dont think I like the elbow grease part - actually much safer than messing with machines. I still laugh..or cry... when I see a nice car with a finish destroyed by someone who bought a buffer without understanding it requires a different formulation of polish than hand applied stuff.
The internet is full of demos of toothpaste mixed with peanut butter is supposed to fix CD scratches

Great for motorcycle windshields and head light/tail light lenses as well.
Never had a scratched CD of my own, but we get LOTS of bad DVD's from the library and it works well for those.
I guess I will try it - true though that I used some autobody polish and glazes before to do plastic parts on the car and it worked well but then didnt do well on CDs - my guess is it wasnt fine enough - I think I recall using a plastic automotive polish on the car parts and it was in essence too weak as the first step for heavier oxidation

I would experiment with some CDs or DVD from the library. ;-)

MikroSmooth does seem popular.
