8 Amazing Survival Uses For WD-40

WD-40 is likely in your toolbox, in your garage, or somewhere in your house. You’re not alone, either – millions of people worldwide have this amazing tool stored away in their home.

And why wouldn’t they?

With its ability to help unstick computer keys, lubricate sticky doors, and open up gummed up locks, it’s easy to see why this impressive spray has a rightful spot in every household.

However, it turns out that WD-40 is way more useful than people think. For instance, it’s not just a lubricant. It also displaces water (meaning it moves water away from whatever you spray it on). Hence its name: WD = Water Displacement.

And, since it contains a variety of chemicals which lubricate, prevent corrosion, and more, the amount of ways you can use this spray just became practically endless.

So, before you think you know everything about this product, make sure to learn about these…

8 Amazing Survival Uses For WD-40

Dig More Effectively

If you’re digging a hole for a shelter or a survival garden, it’s going to be a lot easier with WD-40. That’s because, by spraying this all over the blade of your shovel, the WD-40 will lubricate it, helping the dirt slide off with ease. It’s surprising how much time this can save you!

Keep Survival Food Away From Bugs

Here’s a trick – if your only available food storage is a container with an open top, simply spray the bottom and sides of it with WD-40. This will help prevent bugs and vermin from wanting to climb up the container and sneak inside.

Extend The Life Of Your Survival Tools

It’s surprising how many tools can perform more efficiently (and last longer) with a good spray of WD-40. For instance, spraying this on wooden tools will prevent them from splintering, and will help keep water from ruining them. It can also prevent metal objects from rusting, and can lubricate squeaky joints.

Reduce Snow Buildup

If you’ve got a bug out vehicle, do yourself a favor and spray WD-40 on the windows before a big snowstorm. The spray will help displace the water, and will help prevent snow and ice from building up on your windows.

Start A Fire

If you’re needing to warm up your hands or cook survival food, you can do so pretty quickly with the help of WD-40. Just spray a bit on your kindling and, since the chemicals are flammable, they’ll ignite in no time.

Lubricate Your Gun

Turns out WD-40 is a wonder when it comes to gun cleaning. And, although you shouldn’t rely on it solely (you’ll want to consistently use a good gun oil and cleaner) , it’s a great tool to take advantage of when SHTF. Spray the WD-40 on the inside and outside of your firearm to clean, protect, and lubricate it in-between uses.

Drive The Bugs Away

This can be exceptionally helpful if you’re bugging in during an emergency. Spray WD-40 around areas that wasps tend to congregate. The chemicals inside will help drive them away, and will help prevent the insects from building their nest there.

Chop Down A Tree

Anyone who’s been chopping down a tree can tell you how hard it is. Thankfully, you can exert less effort and still get the job done by spraying WD-40 on the blade. This lubrication will help stop the knife/axe/hatchet from getting stuck in the tree, thereby speeding up the process.


We wrote a survival article about WD-40 a couple years ago, but wanted to update it with additional uses (hence the reason for writing this one). Take a look at the original for more ideas on how you can use this survival tool in emergencies.

  1. When it comes to really deep cleaning your firearm, Simple green is probably the best. Non flammable, and not hard on your skin. Simply completely disassemble the gun, place all the parts on your wife’s cookie sheet and spray with simple green. You’ll be totally surprised how quickly the gunk just drips off. Use a tooth brush for the really gunky parts. Place all the parts in a 3lb. coffee can filled with water (ya must wash off all the simple green or it could harm the metal). Dry all the parts (in your wife;s oven on the lowest setting), or what I do is use compressed air. You won’t believe how clean all the parts are. Then back on your wife’s cookie sheet (which by this time is now yours) and spray with Break Free. Rub the Break Free into each part and then wipe with a paper towel and reassemble. You now have a very clean and lubricated firearm. This process comes from the American Gunsmithing Institute.

  2. The LAST time I used WD-40 on a revolver was several years ago. It bragged about its anti-rust ability, etc., so I sprayed it on when the revolver was going to be stored for a comparatively long time. When I was going to the range the next time, I took it out of the vault, checked it to be sure it was empty–it was–and TRIED to squeeze the trigger. IT WAS LOCKED-UP TIGHT and required a thorough cleaning before it would be serviceable. I have used other lubes and oils since then and WD-40 has been relegated to use as “bug spray” until it’s used up. Then WD-40 will NOT be in my home, car or anywhere I need lubricating products.

  3. I was already a wd-40 user, but this was good because any additional knowledge of uses is a good and helpful piece of information,thanks!!!

  4. One interesteresting use is to spray on wounds for healing i have used this on animals and myself for years and healing is fast and no scars in most cases + i’m 82 going strong
