If when you buy a brand new CD you get it home and breathe heavily on it you are almost always going to see a pattern in the mist on the disc that must have been left there during the manufacturing process. This pattern is very probably a chemical residue that could impede the laser in your CD player. If you now take an 80% solution of Isopropyl Alcohol (Propan-2-ol) and distilled water it is very easy to clean off this chemical residue and buff up the disc.
Do not think that you can use washing up liquid. You can't. Washing up liquid contains a mass of chemicals designed to make one's hands soft and delicate. The main chemical here is Glycerol and this will leave yet another coating on your CD's.
How does it affect your listening pleasure...??? Try it and see. IPA should be available from any good pharmacy and distilled water is readily available by the shedload from filling stations. Failing that, get a friend in the chemical industry. Never use Acetone. This will dissolve your CD.
