The best overall lubricant to use on a garage door is a silicone-based garage door lubricant spray or a white lithium grease spray that is specifically labeled for garage doors, as these two types cover almost all needs. Silicone-based spray is considered the best all-purpose choice for most homeowners because it is clean, easy to apply with a straw nozzle, works in extreme temperatures, resists water, does not attract a lot of dust, and is safe for both metal and nylon parts. It is ideal for rollers, hinges, and bearing plates. White lithium grease is thicker and longer-lasting, so it is the best choice for heavy metal-on-metal contact like metal rollers with exposed bearings and the torsion spring coils where you want the lubricant to stay in place longer. Many professionals recommend having both and using silicone for most parts and lithium for springs and metal rollers. Dry PTFE or Teflon spray is another excellent option for rollers because it leaves an ultra-clean dry film. The best brands include WD-40 Specialist White Lithium Grease, WD-40 Specialist Water Resistant Silicone Lubricant, Blaster Garage Door Lubricant, and 3-IN-ONE Garage Door Lubricant. Avoid standard WD-40, motor oil, and heavy wheel bearing grease.
