I have a Plextor 716UF. I got it used from someone who is a fairly heavy smoker. (Nobody in my own household smokes, so from now on, it will only be exposed to typical household dust.)
I don’t have any problems now, I’ve barely used it yet, and so far, just for reading CDs.
I want to know a few things about cleaning the lens:
Is it ever necessary to clean the laser lens?
How will I know when it’s time to clean the lens?
How do I clean the lens; what products and methods do I use?
Other than the lens, is there anything else to clean?
