Logitech G600 MMO Mouse: Scuffed Laser sensor, jittering cursor

love this mouse for its versatility, but i keep getting cat hairs in the sensor. i must have gotten overzealous cleaning out the hairs one day 'cause now my laser's focus bead or whatever it's called looks to be a little scuffed. barely noticeable to the eye, but it makes the mouse unusable in games and even basic computer functions.

tl;dr: i scuffed my sensor, is there a takedown guide so i can rip the sensor out and maybe buff out the scuffs before i spend another 50 on a new mouse?
