If it's isopropyl/rubbing alcohol, that contains oils which may be the cause of the haze. Pure 90% or higher shouldn't leave any residue from the alcohol.

What I found in cleaning many lasers is that I first use a dry tool to remove as much dirt and dust as possible. Whatever liquid is used can mix with dirt and dust and cause haze. The haze is easily visible and as long as you repeat that step until no haze or residue is present youre good.

Dick,
Since I was using 99% pure Isopropyl alcohol, perhaps the large sonic improvement was in fact attributable to the anti-static ingredient of the Memorex OptiClean left on the laser lens.
There's no question that fast-rotating discs do generate substantial dynamics-degrading static. Have long used the Marigo Audio Ultima Signature Mat with each CD/DVD to block much of their static buildup during play. The mat also much reduces CD micro-vibration and I attach the mat to each disc with removable double-sided 3M Scotch tape in order to stop micro-vibration from air flowing in between mat and disc.
By contrast the detail/ clarity improvement from demagnetizing/ smoothing CD magnetic fields with the Walker Talisman has never seemed comparably satisfying to me although I generally go through the full routine of two-stage cleaning, Marigo Mat attachment, Talismaning front and back before each play.

Musetap, old guy 42 and Awe-d-o-file,
Many thanks for the welcome back.

I've owned the same CD player for ten years or so and I've never cleaned the laser lens. No tracking problems or degradation to the sound quality that I can detect. Guess my hearing is deteriorating at the same rate as dirt accumulation on the laser.
