How to Lubricate a Garage Door

Before you start lubricating, take some time to clean the tracks on the garage door. If you don't clean them, the dirt and debris buildup can create a gritty texture when mixed with the lubricant, which can potentially damage the door. 

Start by vacuuming up any dust or large debris, then wipe down the tracks with a damp cloth. Next, apply a mild detergent to a cloth and wipe down any areas with stubborn dirt. If there's any rust, mix a solution of 1 part water and 1 part baking soda to create a paste. Then apply the paste to the rust using an old toothbrush. Rinse with warm water.

To keep yourself safe while lubricating, disconnect the garage door opener. The disconnection process depends on the garage opener, but there's often a rope with a handle hanging from the garage door's center rail. In many cases, if you pull that, it will disconnect the opener. But to be safe, check with your garage opener's manufacturer for instructions. 

After disconnecting the garage opener, start applying a silicone- or lithium-based lubricant to the door's hinges and rollers. The hinges are usually located near the center of the door panels, and the rollers are small wheels attached to the door that fit onto the track. 

Hold the lubricant can about one foot away from the hinges and spray it all over, paying close attention to where any components move next to each other. Repeat this process for the rollers, using the thin straw attachment that usually comes with lubricant to reach any tiny ball bearings.

Next, use a ladder to lubricate the garage door springs and bearing plates. The springs are usually found above the garage door when it's closed and parallel to the horizontal tracks on both sides of the door. The bearing plates are usually circular and located on each side of the springs.

Spray all springs and bearings with your lubricant. Then manually open the garage door to help evenly spread the lubricant onto the components. 

Locate the top rail and arm bar. The top rail is located on the ceiling and usually has the garage door chain traveling along it. The arm bar is a piece of metal that attaches the garage door to the top rail. Spray both of these areas with lubricant, holding the can about one foot away from each piece.

Finally, locate the lock, which is typically attached to the arm bar you lubricated during step five. Locks usually comprise a keyhole and a T-shaped or L-shaped handle. Spray the entire lock with your lubricant, using the small straw attachment to tackle any small crevices. 

Once you're done lubricating all of the garage door's components, reconnect the opener. This process depends on the opener, but it often involves pulling the rope you used to disconnect the opener in the opposite direction. So if you disconnected the opener by pulling the rope toward the garage door, you can often reconnect it by pulling it away from the garage door. But check with your manufacturer for accurate instructions.
