What're you using to re-lube drives? I've overhauled a ton of floppy and CD drives lately, so just curious what others are doing.
I got a tube of white lithium grease at the hardware store that I use for worm gears, normal gears, disc tray gear paths, 3.5" disk loading mechanisms with metal-to-metal contact, the part that stabilizes the head in operation and lifts it when the disk is ejecting, etc. I've found some stuff online that says you're supposed to use a lighter variant of white lithium grease for this stuff, but whatever I have (intended for general hinge and gear use?) seems to work really well. Everything comes out operating more smoothly and quietly than before. Some of the gunk I wipe off is much thicker than what I'm putting on, so I assume it's OK.
For the polished rails (floppy and CD, non-geared side of the head / pickup mech) I use silicone oil. I just saturate the end of a Q-tip and wipe it on liberally.
