Laser Lens Cleaning

Posted by Dryginger2 (A) on June 25, 2016 at 16:42:13

Having replaced the top aluminium cover of a Denon's DVD/CD player with a custom-cut (but less tightly-fitting) acrylic sheet, I have since had to clean the laser lens far more frequently as the sound otherwise gets muddy and sometimes video stops tracking. For this purpose I have always used Isopropyl alcohol on a Q-Tip and mistakenly assumed that nothing else would do a better job as the cleaning agent.

Recently I substituted fluid from a 14-year-old bottle of 'Memorex OptiClean Cleaning Solution' (now no longer in production) to the Q-Tip in cleaning the laser lens out of nothing more than curiosity. To my surprise the resulting increase in dynamics for both music and movie soundtracks is much stronger than had ever been achieved from cleaning the laser lens with Isopropyl alcohol.

So my purpose in starting this thread is to invite those using Isopropyl alcohol to try substituting an optical cleaner instead and report your findings here.
