Now we can argue whether breath or alcohol will break down the cd faster since saliva is intended to help break down food would it be worse than alcohol on a cd?

I never said I spit on my CDs... It's mostly just water vapour that then condenses on the CD.

I know you menat you were not spitting on them. the vapor that comes out of people's mouths is not water. Even if it s water, would the minerals that are found in water. Depending on where a person lives determines how much and what type of minerals are in the water. Even with a water filter there are still some minerals.

Alcohol on the other hand does not have any minerals, so it is not as abrasive as water (of course I am referring to 99% alcohol). The problem with alcohol is that it's chemcal quality takes off some the coating on the disk.

(one of these days I'll figure out how to quote correctly)

If you drink three or four glasses of Absolute vodka BEFORE trying polishing a CD the whatever is in your mouth will be VERY like Alcohol, .....but you would probably lose interest in the actual CD polishing....

Yep, some toothpastes are good, not all of them though.

Best product is BRASSO or similar polishing pastes, read here:

Try distilled water

I would not recomend using gel toothpaste! The abbrasive in it is much coarser than in regular toothpaste.

Breathing on a disc deposits halitosis and water (in a small quantity). The amount of water shouldn't do any damage but the halitosis could peel the information layer off. Check first by breathing on wallpaper. If it peels, then use the toothpaste, gel or regular, on your teeth. Then breath on the disk.

All kidding aside I find that car polish will get the job done so you can make a copy.

My cousin told me to do this, but my cd got fully erased after i tried the toothpaste trick. It was probably the kind of toothpaste i was using, and i was quite careless too. So remember folks! BE GENTLE!!!

i wanted to mention this freeware that can help you identify where on the disc the scratch is:

@digiratiprime - Wow... that looks like a very very handy piece of software... *downloads*

Thanks!

Ditto as above.

Nice find!

Be careful with extremely badly scratched discs, as in the high speed of rotation of most drives today (7000+ RPM) deep scratches can cause stress cracks and cause the disk to shatter under the force of the rotation.
