How to grease garage door rollers? 

Before you grease your garage door rollers, make sure to cut the power to avoid any accidental movement. Then, clean the garage door tracks by removing old grease and debris with a rag or brush.

When applying lubricant:

• Use thin, even coats — you can always add more later
• Avoid oil-based products; use garage-door-safe silicone or lithium-based lubricants
• Wipe off excess grease immediately with a clean cloth to prevent imbalance

Whether you have steel or nylon rollers, proper lubrication can improve performance and extend the life of your system.
