Just wondering if anyone of you here regularly use cd disk drive cleaners...coz I am a little worried that it might does more harm than good. Will it possibly scratches the lens of the disc drive..or it is perfectly made not to cause this? Also, even if Ipods and celphones with mp3 player is now very popular...I still fond of my sony discman portable player. Its been two yrs since I own this and played lots of good music cd's on it. But just recently, I noticed that the sounds of some of CD and CD-R I am playing becomes not clearer as before, the sounds got lower on volume even if the volume control is already in high. I already bought a dvd/vcd cleaner cd to clean up any dirts that might possibly in it but improvements in sound is just minimal and not as I expected. I want it to be very clear just like before as new. Do you know some effective but safe way/s to manually clean the lens of my portable discman player? Coz I am worried that I might damaged the lens coz it is very sensitive to touch.
