How to grease garage door rollers? 

Before greasing your garage door rollers, cut the power! Then, you can remove any grease from the garage door tracks and start greasing the rollers. Use even layers, and don’t apply too much at once. You can always add more later, so only apply thin coats of lubricant. 

No matter which type of rollers your garage door has, you should avoid using oil-based lubricants and immediately wipe off any excess grease with a clean cloth.
