What kind of lubricant is used for car door handles?

[VonPaislee]

Car door handles are lubricated with silicone grease, and the following is relevant information: 1. Lubrication: Car door locks include the lock cylinder, lock body, interior handle, exterior handle, interior locking mechanism, linkage, latch, and striker, among many other components that require lubrication. Special-performance grease should be used, and if budget allows, silicone grease is the best option. 2. Door: The car door (car door) provides access for the driver and passengers, isolates external interference, mitigates side impacts to some extent, and protects the occupants. The aesthetics of the car are also related to the design of the door.

I often do my own car maintenance, and applying lubricant to door handles is something you can't take lightly. I recommend using a dedicated white lithium-based grease—it doesn't attract dust and is waterproof, keeping door handles smooth for a whole year. Personally, I use a small brush or cotton swab to apply a little to the handle pivot and spring gaps. Never use engine oil or regular grease—those attract dust and will make the mechanism stickier over time. In winter, freezing is a big concern, but lithium-based grease won't clump even at -20 to -30°C, making it very reliable. It also won't wash off easily during car washes. Before applying, remember to clean off old grease and dirt with a damp cloth. A thin layer is enough—applying too much can stain the door trim and look messy.

As a veteran mechanic with over a decade of workshop experience, I recommend car owners to directly purchase spray-type graphite lubricant for door handles. This stuff gets the job done with just a spray—no need to disassemble parts, and it can penetrate into tiny gaps. The operation is super simple: wipe the handle clean, shake the can well, spray twice from 20 centimeters away, then just work the handle back and forth a few times. But be careful not to spray it on the car paint, otherwise it'll leave gray marks. It's better than liquid engine oil, which tends to drip everywhere and attract dust. Graphite lubricant won't damage rubber seals, and one application lasts about half a year. If you really can't find specialized lubricant, sewing machine oil can be used as an emergency solution, but remember to switch to professional products afterward.

Ever since my new car's door handle started squeaking, I've done specialized research on lubricants. Household WD-40 should never be sprayed directly on the handle—it's great for rust removal but doesn't provide long-lasting lubrication. I've tried silicone-based spray; it's colorless, odorless, and doesn't attract dust. After spraying, the door opens and closes as smoothly as when it was new. Before spraying, use a toothbrush to remove tiny sand particles from the handle gaps, or even the best lubricant won't help. During the rainy season in the south, silicone-based lubricant works especially well for waterproofing and isn't easily washed away by rain. It's a bit more expensive than grease, but it saves time and effort. Just a couple of sprays during each maintenance session takes less than a minute, making it perfect for busy car owners like me who don't have time for fuss.
