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!

my condolences to all "soap-a-holics" and "alco-holics". it's realy a time to produce some vpi or nitty gritty cd-cleaner with vacume action or something to add another category for "vpi- or nitty gritty- holics".

hint1. i simply wash my hands with hand-soap(prefere oil of olay but irish spring also will suffice) and it's sufficient. if my hands are too greasy after some mechanical job i use at first corn-oil and than hand-soap. i

hint2. jewel boxes are made so you don't have to touch and leave fingerprints on the play surface.

I clean all my CD's with a vacuum cleaner using a crevice attachment while listening to Madonna's "Get into the Grove"! You'd be suprized at all the lost change, & missing socks that are at times found in the Compact Disk Groves during spring & fall cleaning sessions!

** I don't use soap. It can clog the grooves

I believe what 7671 was referring to are the pits on the CDs, not the grooves. Now, I don't know if soap can necessarily clog these pits per se, but it can probably leave residue that could diminish the CDs reflectiveness, which is as bad as clogging them.

Actually the "pits" are molded into a reflected layer which is then coated with a smooth protective layer. The CD surface is completely smooth - no pits to clog.

I use kodak lens cleaner or eyeglass cleaner with a non-woven eyeglass cloth from a small spray bottle. Works great and is very gentle. Photo optics and plastic eye glass lens material is very suseptible to minute scratching. Figure if it is safe on these sensitive materials it would be safe on CDs.
