It is always a good idea to keep your garage door and opener lubricated. However, the Genie garage door opener carriage in the picture shows what happens when you apply too much grease.
You should use a light spray lube on the hinges and rollers of your door. Your local hardware store will have a spray formulated for garage doors. While you are in the lubricant department at the hardware store grab some low temperature grease for your opener rail.
You should lube your garage door rollers, springs, hinges, and tracks about three or four times a year with spray lubricant. The rail on the opener should only be lubed once a year with the low temperature grease. Over application is messy and the stuff stains whatever it comes into contact with.
That should keep your door running quiet. If you find your door needs a lot of lubricating throughout the year you may need to have it tuned up. If you are in the Fort Worth area give us a call for a free estimate.
