Lubrication: What to Use and What to Avoid
Half the noise complaints that get quoted as a repair are solved with ten minutes and the right can. The maintenance page at Garage Door Repair Long Beach CA Adams Bev Group covers this before anything expensive, because the wrong product on a garage door does real harm, and salt laden air in Long Beach makes the choice matter more here than it does in a dry climate.
Why the Usual Aerosol Is Wrong
The blue and yellow can in every garage is a water displacer and a solvent. It thins and washes away what is already there, then evaporates and leaves the metal drier than it found it. Sprayed into a sealed bearing it dissolves the packed grease and shortens the life of the part it was aimed at. It is fine for freeing a seized bolt and wrong for everything else on the door.
What to Use Instead
A white lithium grease in spray form, or a purpose made garage door lubricant, is what the moving parts want. It stays where it is put, tolerates heat, and does not run down the door skin. A light machine oil suits anything with a pivot pin. Neither of them should be applied so heavily that they drip, because a wet part collects dust and grit and turns it into a grinding paste.
The Points That Want Lubrication
Work with the door closed and the power off. Hinge pivots at each knuckle. Roller stems where they pass through the hinge, and the bearing face of any roller that is not sealed. The end bearing plates at both ends of the torsion tube. The torsion spring itself, coated lightly along its length so the coils slide against each other. The lock bar and any keyed cylinder.
The Points That Want Nothing
The track running surface is the big one. A greased track collects grit, and the wheel then rides on a slurry instead of on steel. Wipe the inside of the rail clean with a dry cloth and leave it dry. A chain rail wants only the film the manufacturer specifies, applied to the rail rather than the chain, and a belt drive wants nothing at all.
The Coastal Adjustment
Within a mile or so of the water this is a twice yearly job rather than an annual one, and the spring coating matters most of all. A film of lubrication on a spring keeps the chloride off the wire surface where corrosion pitting starts, which is the pitting that ends up ending the spring's life early.
Doing It in the Right Order
Wipe first, lubricate second. Applying grease over a layer of salt dust seals the salt against the metal, which is worse than doing nothing. A cloth over each hinge and roller before the can comes out takes an extra five minutes and doubles the value of the whole exercise.
