Auric Illuminator on CD's

Hi,
I tried the A.I. on the CD's & was quite please with the outcome. However when I played some discs which were treated a few weeks back they started skipping quite a bit. Sometimes they would even skip across tracks. It is to be noted that the CD does not skip when the disks have just been treated with the liquid, but only after storage for a few weeks.

I tried washing the disk to remove the liquid ( marked edges with black still remaining ) & replaying them but still the skipping was persistent.

Now I am afarid to apply this to anymore disks. Has anyone elese faced this problem?
