Well, I tried to install BG2 and I discovered, that CD 1 was dirty, so I need to clean it. But how?

With a soft, dry cloth. Start from the center and go straight to the edge. Do not go around in circles. Breathing on it first can help.

Dry cloth? I always clean dirty CDs in lots of water, then dry them afterwards with toilet paper :p . They always work.

Sure soap and water are fine. You just don't want to use anything that's a solvent to the plastic.

And Jack is right: Soft cloth and radial, not circular strokes. The reason for that is to minimize harmful scratches. The information is recorded in a spiral pattern around the disk. If you have a radial scratch, chances are the built-in error correction can handle it; if you scratch along a track, too much information could be corrupted.

With care. Using sharp, pointy instruments to scratch the dirt from the printed upper surface is generally not recommended. Benzene, spittle, spirits also have to be considered unsuitable for the cleaning of CDs. Mind that CDs (copies especially) should not be exposed to light, that reduces their durability. When destroying a CD by clumsy cleaning with a steel broom for example - don't cry: There are CD repair kits available, allowing you to correct minor scratches.

So it's not that Jack Funk, BTA and Mollusken are very wrong with their points of view about CD cleaning, to the contrary.

Here is a way to clean/rubb out very light scratches: Get the CD wet, rubb some tooth paste on the CD using your fingers (60% water 40% tooth paste). Keep rubbing the CD untill the whole surfaceg is covered in tooth paste foam. Then rinse the CD clean. This has always worked for me. :rolling:

I've always used 70% isopropyl. You can buy 90% isop at target.

Yes, it leaves a slight powdery coating; but if you're cleaning it with a soft cotton cloth, the instant it dries, your next wipe will remove that coating.

There's a lot of things that go into solution with isop. Including oil and dirt (nonpolar substances)...

My deepest thanks. I am following your advice and i hope it works.
