Two cans cover the whole door. Here is the split.
The slick parts
Use it on: nylon rollers, hinge pivots, the spring coils, weather seals, and anywhere plastic touches metal.
The loaded parts
Use it on: steel hinges, roller bearings, the bearing plates at the ends of the spring bar, and a screw-drive opener rail. All of them carry real load.
The trade: lithium stiffens in deep cold and grabs more dust than silicone, so use it where the load is, not everywhere.
Two silicones, two lithiums. Most doors want one of each.
Top picks at a glance
Best for: the default can, a silicone spray made specifically for door hardware
This is the can the category is named after, and it earns the spot. The spray goes on wet enough to creep into hinge pivots and roller bearings, then sets to a dry slick film that does not hold dust. The flip-up straw matters more than it sounds: stream mode reaches the top hinges and spring coils from a step ladder without misting the car. One can does a double door twice a year for years.
Skip it if: your hinges and bearings are bone-dry steel under heavy load. Pair this with a lithium can instead of asking silicone to do grease work.
Best for: the same silicone job at a value price, with a straw you aim into tight pivots
B'laster built its name on penetrating oil, and its garage door silicone is the straightforward alternative to the 3-IN-ONE can: same chemistry family, same tack-free film, routinely the value pick of the two. Performance differences between these silicones are smaller than the difference between either and a door that never gets sprayed. Buy whichever is on the shelf and do the job this weekend.
Skip it if: you want one can for every part including loaded steel bearings. Same answer as above: silicone quiets, lithium carries load.
Best for: hinges, bearings, and screw-drive opener rails, the metal-on-metal half of the job
Yes, the company we warned you about. The Specialist line is real lubricant, and this can is the right one: it sprays as a thin liquid that reaches into the bearing, then sets up as a white grease that stays in the contact patch under load. Steel hinge pivots, the bearing plates at the spring bar ends, and screw-drive rails are its territory. Keep it off the weather seal, where lithium can swell some rubbers, and keep both cans in the garage.
Skip it if: your whole door is nylon rollers and vinyl seals. Silicone covers that door by itself.
Best for: the budget lithium can from a shop-brand name, same chemistry, fewer frills
CRC is a workhorse industrial brand, and this is the no-story version of lithium grease: sprays on, sets up, clings through weather. It covers the same hinge and bearing duty as the WD-40 Specialist can, typically a notch cheaper, with a simpler nozzle. If the garage shelf already holds CRC products, stay in the family and put the savings toward a better silicone.
Skip it if: you need pinpoint stream control for high hinges. The two-way straws on the picks above aim better from a ladder.

The blue-can WD-40 is a penetrating oil and water displacer. It frees stuck parts and cleans grime, then mostly evaporates, leaving the metal close to dry and sometimes stripping the grease that was doing the work. Garage door lubricant is silicone or white lithium that stays on the part for months. Use the blue can to clean a gummed hinge if you must, then follow it with real lubricant. Note that WD-40's Specialist line includes proper lubricants, which are fair game.
Both exist and both are correct, on different parts. Silicone sprays go on thin, dry to a slick non-sticky film, and stay flexible in the cold, which suits nylon rollers, weather seals, and anything plastic. White lithium is a thicker grease that clings to metal-on-metal contact, which suits steel hinges, roller bearings, and the opener's screw rail.
Yes, and you should: a light, even mist along the torsion spring coils quiets the creak the door makes under load and slows rust. The rule is spray only. Do not adjust, unwind, or unbolt anything attached to a spring, and keep your hands off the winding cones. Spring tension work belongs to a door tech.
Hinges at their pivot points, roller bearings where the stem meets the wheel, the torsion spring coils, the bearing plates at each end of the spring bar, the arm pivots on the opener, and the opener's rail if it is a screw drive. Wipe the tracks clean with a dry rag and leave them dry. Door down and opener unplugged before you start.
The aerosol propellant is, while you are spraying it. Keep the can away from pilot lights, heaters, and sparks, and let the mist settle before running the opener. Once the carrier flashes off, the silicone or lithium film left on the parts is not a meaningful fire concern. Treat the can like any aerosol: garage shelf, not on top of the water heater.
Got the cans? Now put the job on a schedule. How often to lubricate a garage door covers the by-household calendar and decodes the noises, and the garage door hub draws the line between homeowner jobs and spring-tension jobs you should never touch.
