Cleaning Laser Lens on CD and DVD players
Q: CD Player Repair. Sir/Madam, a good tip for fixing a CD player is to clean the laser lens with methylated spirits or - preferably isopropyl alcohol, (doesn't leave residue). I've got to the point now (after 10 years) where it doesn't work on my CD player, any tips? -- Reggie H Reply (Ref:0279)
Answer #1: Make sure the player is off as laser may permanently harm your eyes - Gallileo Comment
Answer #2: You can buy a special disk that has a small brush like projection that cleans off the dust. Ethanol or other alcohols can speed up the process. If you are confident you can open up the player and clean with alcohol on a cotton bud.-- TTB Comment
