I've had fair luck by pulling the sheet metal rad covers (with it out of the 
machine and powerless) to gain access, and using an alcohol dampened Sheperds 
Medical q-tip to very gently clean the face of the lens.  Emphasis on the 
gentle, they are very easily mount damaged as the servo can only move so much 
weight at 10 khz to track a wobbly disk at 52x, so every grain of extra 
weight has been designed out of it and the suspension.  I have probably 
damaged as many trying as I have fixed, and I can have a very gentle touch 
when indicated.  And that is dampened with paint thinner alcohol, isopropil, 
even the 90% stuff has too much water in it and will do a poorer job of 
dissolving the cigarette smoke & airborne cooking grease etc that collects on 
this stuff, and which may become pretty well baked on when the controller 
turns up the laser trying to see through it.

Good luck :)
