I developed through experience and trial and testing this method to clean practically any device lens (laser diode). It's brought many a laser based device back from the dead and has been invaluable many many times, it can be used with any type of cd player dvd player or console including blu ray players.
Items required are cheap and easily sourcable
1.a single double sided cotton ear bud
2.a dvd/cd or blu ray lens cleaner disc with bristles, this depends on the device your cleaning obviously
3.And mentholated spirit the clearer toned purple stuff not the dark toned liquid preferably
Any way hope it helps i have used it for a denon system, many consoles and some blu ray drives and dvd players, pc dvd-rom drives you name it.
It's the first thing i do if a drive isn't working on reading discs no matter what it is, then failing that try pot tweaking and after that replace the laser if it's not working.
Enjoy!
