I have some polycarbonate cleaner that we use and a few microfilter cloths to wipe the discs clean (wet or dry). I forget the brand, it wasn't audio stuff, it was some commercial stuff for polycarbonate windows on pinball machines. We got it on eBay.
For scratches we have some various levels of commercial polycarbonate scratch remover that we apply, scrub, and remove by hand (for light scratches). Again, it's stuff for pinball machines.
for deeper scratches we have the motorized Skip Doctor (ca.$30 or $40) with some polishing compound. Although the wheel marrs the surface, it's better than having to throw the CD or DVD out. (we buy a lot of CDs, DVDs, PS2 and XBox games used).
For serious listening sessions I'll also hit the CDs with the Mapleshade Ionoclast zapper gun (similar to a Milty or zerostat). With the ionoclast treatment I notice increased low-level detail retrieval (CD apparently sounds louder). The treatment seems to last for about 6 plays.
