Before applying any fresh protectant or lubricant, you must clear out the old, gummed-up grease. Cold weather causes standard grease to solidify into a sticky paste that traps debris and forces your opener to work twice as hard.
Use a clean rag and a heavy-duty degreaser or solvent to wipe down the internal tracks, rollers, and hinges. Clear out all accumulated sludge so you are working with bare metal surfaces.
Never use standard WD-40 or heavy grease for winter lubrication. Standard WD-40 is a solvent, not a long-term lubricant, and thick grease will freeze. Instead, use a high-grade silicone or lithium-based spray specifically designed to withstand extreme cold without becoming viscous.
A specialized, heavy-duty formulation designed to resist freezing temperatures, prevent rust, and eliminate noisy operation without attracting dust and grime.

When the opener tries to force open a frozen bottom seal, it can strip the drive gear or tear the rubber completely off.
Inspect the perimeter seals for gaps. To prevent the bottom seal from sticking to ice, apply a thin coat of silicone spray or specialized rubber protectant along the entire bottom edge.
If your current seal is cracked or brittle, replace it with a durable T-rubber or U-ring bottom seal designed to maintain flexibility even in extreme sub-zero conditions.
