Old timer told me to stop greasing the door tracks every month and I thought he was nuts at first
He showed me how the excess grease was actually attracting more dirt and causing binding on a 10-year-old Otis in a St. Louis office building, so now I only hit the bearing points with a dry lube once per quarter - anyone else had a senior guy change your whole maintenance routine?

The dry lube trick works because you're not just reducing dirt buildup, you're actually letting the door's own balance do its job without resistance from sticky gunk. A lot of guys never consider how excess grease masks worn bearings too, since the lubrication compensates for slop that should tell you something needs replacing. I had a similar wake-up call years back and now I keep a can of silicone spray strictly for pivot points.

Actually, silicone spray is a dry lubricant that dries to a film, so it's fine on pivot points. But you might want to be careful with it on the track itself. I found that out the hard way when my garage door started sticking after a few months. The silicone built up on the nylon rollers and left a residue that grabbed the track when it got cold. WD-40 Specialist makes a PTFE dry lube that works better for the track since it leaves almost no film.
