Choose the Right Lubrication
The best lubricant is the ones that are specifically for garage doors. This spray is formulated specifically for garage doors. The cheaper sprays come out in color and also spray out so much you can hit the hinge 10ft away. Also they drip a lot and can be huge safety hazard if they drip down on a epoxy floor and then someone can slip and fall. Do not use a WD40. This is not a lubricant. WD40 has a cleaning agent that will break down grease and remove the grease from places that has grease packed around the bearing.
