Great news ... but "Al Bundy" passed away almost *ELEVEN YEARS AGO* while
waiting for your sage advice.

(Why can't you Home Moaners Hub people read DATES?)

I can only imagine that they can't see them. No one ever cites them.

And aside from that, it sounds like a frigging mess. If a garage door
opener is working, I'd leave it alone. If it needs some lube, I'd
apply it without cleaning out the old lube.

The old lube will get the new lube dirty.
