I bought a secondhand CD Video single (The Timelords' Doctorin' the Tardis, if you must know) recently. It has an audio and laserdisc layer, so three tracks play on the CD player, and the video will play on a laserdisc player, not that I have one of those. The audio seems fine, which is why I bought it. However, I noticed that the front of the disc had finger smudges, so I attempted to clean it, first with a fibre optic cloth, then a baby wipe, then an antibacterial wipe. I also tried window/glass cleaner. The underside (playing side) of the disc looks fine. However, in common with other plastic surfaces around the home, the wipe has left cloudy/swirly marks on the disc label side, which is a bit annoying. I haven't had this problem with other CDs (not that I clean many), but those are standard silver discs. This one is gold-coloured. I wonder if it's similar to the MFSL discs in that sense. Browsing around, laserdisc collectors often seem to recommend using Novus on plastic. Has anyone tried anything like this on gold/bronze laserdisc surfaces or similar? I'd like to get rid of the swirls. Recommendations appreciated please.
