Clean off any dirt or grease from the rollers and the torsion spring before you begin to lubricate, to avoid creating a sludgy substance of grit and sand that can destroy the metal. You can clean the dirt and grime using a clean cotton cloth. Squeeze two drops of lubricant into the seam of every door hinge on the garage. Work from the top so the oil will seep into the seam on its own power.
Drip in another two drops to the seam of each roller's mount bracket, located in the tracks on the side of the garage door. Add an additional drip on the ends of the pins that hold on the brackets inside the mount, and on the ones right below that do the actual rolling.
Apply six more oil drops to the track of the roller, at about one foot above the track's curve.
Go to the spots where the cables connect into the roller mount brackets at the bottom of the door, and squeeze on another drop of oil where the two parts come together.
Stand on the ladder and draw a bead of oil along the length of the top of the torsion spring, which is connected at the top of the garage door.
Open and close the door three or four times to make sure that the oil distributes completely over the track.
