Keeping the rollers and other moving parts well lubricated will reduce stress on the rollers and door openers and prolong their useful lives. Twice a year, apply a high-quality spray lubricant, such as white lithium grease (which is available in a spray can), on the rollers and hinges, then wipe off any excess. If any rollers or hinges seem stuck, spray them with a penetrating solution, like WD-40, then wipe them clean and apply grease.
Also, lubricate the pulleys on extension-spring openers and the bearings on torsion-spring openers. Wipe a little oil on the torsion spring if it is rusty. If the opener has a metal chain or screw, spray white lithium grease on the opener’s chain or screw, but do not use a lubricant on a belt-drive opener.
