Microfiber cloths are a quick way to clean a DVD. These are the same kind of cloths people use to clean eyeglasses, monitors, and laptop or LCD monitors. Because of microfiber’s very tight weave and the synthetic materials used to make microfiber, dust and particles of dirt are attracted and lifted up into the microfiber, which prevents you from simply spreading the dust around and scratching the DVD further. Every serious DVD collector should have one of these and wash it regularly. Rubbing Alcohol is used to clean DVDs and just about every sensitive piece of technology out there because it doesn’t act like strong solvents do, and it evaporates quickly without leaving a residue. Usually a 1:1 mixture of 90%+ Isopropyl alcohol and water will do the trick. Simply dab a small, clean cotton cloth into the mixture and wipe in straight lines from the center of the DVD to the outside edge. To dry the DVD, just let it sit for a moment or two in a vertical position. Window Cleaner, like rubbing alcohol, is a great way to clean sticky residues and dirt off of a DVD. Like rubbing alcohol, window cleaner is not a very strong solvent, and it evaporates quickly without leaving residue as well. Instead of spraying the DVD, spray a little bit onto a soft, cotton cloth and wipe from the center of the DVD to the outside edge—leaving it to dry by propping it up in a vertical position for a few minutes.
