Which lubricant should I use on a garage door?
White lithium grease or a garage-door lubricant on rollers, hinges, springs and bearings — and not on the track, which should be clean and dry.
The single most useful thing to know about garage doors is not the lubricant but the springs. A torsion or extension spring holds the entire weight of the door under enormous tension, and adjusting or replacing one without the correct bars and technique kills and maims people every year — it is the one genuinely dangerous part of the assembly and it is a job for a technician. Ordinary lubrication is safe and worthwhile: rollers, hinges, bearing plates, the spring itself and the opener's screw or chain. The track is the exception, because grease there attracts grit and the rollers then slide rather than roll. A door that has become noisy or heavy usually needs adjustment or balance-checking rather than more lubricant.
The options, ranked
| Option | Good at | Bad at |
|---|---|---|
| White lithium grease | Clings to hinges, rollers and bearings, survives temperature swings and lasts a year or more. | Sticky, so it collects dust if applied where it is not needed. |
| Silicone spray | Useful on the weather seal and on plastic components where grease would be wrong. | Contaminates any surface that will later be painted. |
| Penetrating spray | Fine for cleaning a gummed hinge before lubricating it. | Not a lubricant here; it washes grease out of a roller bearing. |
| Nothing on the track | Wiping the track clean is the correct maintenance; the rollers are supposed to roll on it, not slide. | Requires resisting the urge to spray the most obvious moving surface. |
Technique that changes the outcome
- Close the door and disconnect the opener before working on it
- Wipe the tracks clean with a cloth; do not lubricate them
- Grease the rollers, hinges, bearing plates and springs sparingly
- Test the balance: with the opener disconnected, a correctly balanced door stays put halfway
What goes wrong
- Adjusting or replacing torsion or extension springs yourself
- Lubricating the tracks
- Ignoring a door that will not stay halfway open, which means the springs are out of balance

Other lubricant questions
| For | Use |
|---|---|
| A bike chain | Wet lube for wet conditions, dry lube for dry and dusty ones, wax if you want the cleanest and lowest-friction option — and not a general penetrant. |
| A lock | A dry lubricant — powdered graphite or a PTFE spray. Oil and general penetrating sprays gum locks up and are the classic way to ruin one. |
| A squeaky door hinge | A drop of light machine oil or a smear of white lithium grease on the pin — and lift the pin out to clean it, which is usually the actual fix. |
| A seized bolt | A dedicated penetrant or a 50/50 acetone and automatic transmission fluid mix, plus time, heat cycles and shock — and anti-seize on reassembly. |
| A squeaky floor | Talc, graphite or powdered soapstone worked into the joint as a stopgap — the real fix is screwing the board down to the joist. |
| A sticky drawer | Paraffin wax or beeswax on wooden runners, dry PTFE on metal ones — and never oil on wood. |
| Rubber seals | Silicone grease on most rubbers, and a PTFE or fluorosilicone product on silicone rubber itself — petroleum products swell and destroy natural rubber and EPDM. |
