Do’s and Do Not’s of Lock Lubrication

Here are a few simple helpful tips to add to the longevity of your locks.


Use WD-40 as your main lubricant

WD-40 is not a true lubricant. The WD stands for “water displacing” and its true use is as a solvent or rust dissolver. WD-40 will act as a lubricant, but the effect doesn’t last; leaving you with metal rubbing on metal, which will greatly decrease the life of your lock.


Use WD-40 as an initial cleaner

WD-40 works great as a first step to fixing a rusted, dirty, or grimy lock. If your lock is sticking, give it a few blasts of WD-40 and let it sit; repeat this process a few times.
If it still is not working, bring it to us and we will give you our expert opinion on what the next step should be.
If the key seems to be working smoother, use one of the later tips to keep your lock well lubricated.


Use Graphite as a lubricant outdoors.

Graphite was an excellent lubricant for it’s time. I’m sure your grandfather used it for everything and still swears by it. While it does still work, there are FAR better options out there.
Especially in our moisture rich Washington climate, graphite can end up causing more harm then good. When graphite is combined with moisture it creates a thick sludge that can cause your lock to behave erratically.


Lubricate your car locks every time you get your oil changed

As a good rule of thumb, we recommend you lubricate your car locks and hinges every time you get your oil changed. This will greatly increase the life of your locks and your keys. Which will in turn make your life a lot easier!
