Just thought I would share my recent experience.

I have two different model Genie openers, one was a LOT noisier than the other. I attributed that to the fact they were different models.

Well, I bought a cleaning kit that came with some silicone spray for the rollers and and hinges and grease for the screw drive. The improvement in sound of the door was incredible. I probably added 7 years to the life of the opener.

I will be doing this at least 1x a year.
