My alpine 9874 headunit is skipping a lot lately. I would like to clean the lens, but I just read in the owner's manual that one can not use cd cleaners. It says to contact an authorized dealer.

How do you alpine owners clean your lens?

Thanks

 

With a cd lens cleaner. If it is skipping what do you have to lose. Normally by the time my headunits get to that point it is a couple of years old anyway.
