hey

i have close to 700 CD-R AUDIO CDS
ive had them for several years now
some of them, despite being kept in a leather binder, are noticeably starting to break down

Some have noticable smears on the shiny surface
Some have noticable jumps and skips in the playback
Some have a scratchy playback with a staticy sound not there before


My question is this

1) is there a program which will optimize my CD-R AUDIO CDS?
note: by optomize, i can also mean refresh, revitalize, rebuild and/or if absolutely neccessary, redo!

2) is there a physical tip or trick to keep my CDS from degrading?
note: Ive used iso prophyl achohol -71%. It doesnt remove scratches but it takes care of dust. I should mention though that exhaling on the CD can also remove dust. So whats the diff? Any other ideas anyone?

3) other than a software solution or a manual tip - any other CD-R AUDIO CD maintenance suggestions would be appreciated

thanks

p.s.
im still looking for free, safe, secure and stable web hosting service. I require several hundred megabytes of web space to upload. Anyone know good recommendations? Its best if the service doesnt have too many useless restrictions like 1kb/file transfer limit, etc..
