do it under a lamp, and use a magnifyer glass (with lot of zoom) to check the surface very often, use the reflect of the lamp light (bouncing in the surface) to see the details

move the cotton stick in circles, but not complete circles.

dont push the lens too much (to avoid bending the coils) Is better if you have a PC reader for practising (or any old laser shit you have at home), the important rules are: Take a look at this thread, i was talking a bit about how to perform some checks to your laserĪnd in this thread i explained how i clean lasers with a cotton stick, is easy when you get used to it, and i do it with lot of devices, not only consoles nowadays the laser pickups you are going to find 'on sale' are not officially made by sony, but who cares ?, are cheaper and works fine The laser pickup doesnt needs any calibration, if at some point you need to replace it the only thing you need to do is to release one of the 'rails' (that metal bars at the sides with vaseline grease), remove the old pickup, put the new one and assemble everythig Some of them (like the tray disc presence sensor) have tiny wires and can break easilly if you pull from it
