How do I clean CDs with isopropyl alcohol?

Hello:

I just purchased some 91% isopropyl alcohol to remove some Optrix clouding (I didn't follow the instructions and wipe the CDs completely dry).

Anyways, my CDs seem to be much more clean than dish soap / water.

So, can others provide me with tips on using isopropyl alcohol for cleaning CDs:
1) Should I use undiluted 91% isopropyl alcohol or should I dilute it with distilled water. If so, what are the appropriate proportions?
2) How long do you leave the isopropyl alcohol on the CD for maximal effect?
3)Any potential to damage my CDs by using this cleaning protocol vs soap and water?

Do you think isopropyl alcohol is safe for CDRs?

Is there any potential for damage to my CDs or CDRs from repeated cleaning with 1) isopropyl alcohol or, 2) soap and water?

Any insights would be greatly appreciated!

i work in plastics and can tell you, poly based cd's (most plastics in general) and alcohol don't mix...

alcohol degrades polys causing crazing-stress cracks,brittleness. if someone has a loupe check out what happens....how can a disc become that dirty to warrant alcohol in the first place?

stick with soap and water.
