15 SHTF Uses for WD-40

A Versatile Survival Tool

In a world where preparedness is key, versatile tools like WD-40 are essential for SHTF scenarios. Since its conception in the 1950s by the Rocket Chemical Company, WD-40 has become a staple in homes, garages, and industries worldwide. The formula, whose name stands for Water Displacement, 40th formula, was originally developed to protect the Atlas missile.

But did you know that WD-40 has numerous other uses in survival situations? In this article, we will explore 15 SHTF uses for WD-40 that you may not have considered. From lubricating tools to repelling pests, this multipurpose product can be a lifesaver in times of crisis.

1. Keeps Firearms in Top Shape

In a post-SHTF world, maintaining the functionality of your firearms is crucial for self-defense and hunting. WD-40 can help in this regard by preventing rust and corrosion on metal surfaces. Simply spray a light coating of WD-40 on your firearms and wipe off any excess oil. This will protect them from moisture and keep them in top shape.

My 2 Cents:

Don’t rely solely on WD-40 for long-term firearm maintenance. Regular cleaning and proper storage are still essential for keeping your firearms functioning optimally.

2. Loosens Rusty Nuts and Bolts

When you come across rusty nuts and bolts that refuse to budge, WD-40 can be a game-changer. Spray a generous amount onto the rusted area and let it sit for a few minutes. The lubricating properties of WD-40 will help loosen the rust and make it easier to remove the stubborn fasteners.

3. Removes Stickers and Adhesive Residue

Getting rid of stickers and adhesive residue can be a hassle, especially when you’re trying to conserve resources. WD-40, however, can make the task much easier. Spray some WD-40 onto the sticker or adhesive residue and let it sit for a minute or two. Then, wipe away the residue with a cloth or sponge. The sticker should come off easily, leaving no trace behind.

4. Repels Insects

In a survival situation, the last thing you want is to be bothered by pests. Fortunately, WD-40 can help repel insects such as mosquitoes, flies, and ants. Spraying WD-40 around entry points, windows, and other areas where insects may enter your shelter can create a barrier that these pests will avoid.

My 2 Cents:

While WD-40 can provide temporary relief from insects, it is not a long-term solution. For sustained insect control, consider using natural repellents or physical barriers.

5. Protects Tools from Rust

Keeping your tools rust-free is essential for their longevity and functionality. Before storing your tools, give them a light spray of WD-40. This will create a protective barrier against moisture and prevent rust formation. When you need to use the tools again, a quick wipe with a cloth will remove any excess WD-40.

6. Removes Tar and Grease Stains

Accidents happen, and getting tar or grease stains on your clothes or equipment is inevitable in a survival situation. WD-40 can come to the rescue by effectively breaking down these sticky substances. Spray WD-40 directly on the stain and let it sit for a few minutes. Then, launder the item as usual, and the stain should be gone.

7. Unsticks Zippers and Stuck Mechanisms

In a survival situation, a stuck zipper or mechanism can be incredibly frustrating. WD-40 can help free up these stuck parts and make your life a lot easier. Spray a small amount of WD-40 onto the affected area and wait for a few seconds. Then, gently manipulate the zipper or mechanism back and forth until it moves freely.

My 2 Cents:

Remember to use WD-40 sparingly, as excess oil can attract dirt and debris that may worsen the sticking issue.

8. Cleans and Lubricates Bicycle Chains

If you rely on a bicycle for transportation, maintaining its chain is crucial for smooth and efficient riding. WD-40 can be an effective cleaner and lubricant for bicycle chains. Spray WD-40 onto a cloth and wipe the chain to remove dirt and grime. Then, apply a bicycle-specific lubricant for long-lasting chain performance.

9. Restores Leather Items

In a survival scenario, preserving the functionality of your leather items can be important. WD-40 can help restore and protect leather boots, belts, and other accessories. Spray WD-40 onto a cloth and gently rub it onto the leather surface, allowing it to penetrate. This will help moisturize the leather and keep it from cracking.

10. Quiets Squeaky Hinges and Doors

Noisy hinges and doors can not only be irritating but also give away your location. WD-40 can help silence these squeaky offenders. Spray WD-40 directly onto the hinge or door mechanism, making sure to reach the moving parts. Open and close the door or hinge a few times to distribute the lubricant evenly.

11. Removes Water Stains from Glass

Water stains on windows and glass surfaces can be unsightly and difficult to remove. WD-40 can come to the rescue by breaking down these stains. Spray WD-40 onto a cloth and gently rub the glass surface. The water stains should start to dissolve, allowing you to wipe them away easily.

12. Protects and Conditions Garden Tools

Garden tools are invaluable for growing your own food during uncertain times. WD-40 can help protect these tools from rust and keep them in good condition. After washing and drying your garden tools, spray a light coating of WD-40 on the metal parts. This will preserve them and prevent rust formation.

13. Loosens Tangled Jewelry

Untangling jewelry can be a frustrating task, especially when you’re on the go. WD-40 can make this process easier by lubricating the knots and tangles. Simply spray a small amount of WD-40 onto the tangled area and gently work the knots apart. The lubrication will help the jewelry slide and untangle more smoothly.

14. Removes Crayon Marks from Walls

If you find yourself with young children during a survival situation, you may encounter crayon marks on walls or other surfaces. WD-40 can effectively remove these marks without damaging the paint. Spray WD-40 directly onto the crayon marks and let it sit for a minute. Then, wipe away the marks with a clean cloth or sponge.

15. Provides Temporary Fire Starter

In desperate times, you may need to start a fire quickly without traditional fire-starting materials. WD-40 can be used as a makeshift fire starter in emergencies. Spray a small amount of WD-40 onto dry twigs or kindling, and ignite it using a spark or flame. However, be cautious when using WD-40 as a fire starter, as it is flammable and can produce toxic fumes.


WD-40 is more than just a favorite household lubricant. In a survival situation, it can become a versatile tool that helps solve common problems. From protecting firearms to repelling insects, WD-40 has numerous uses that can be lifesaving when resources are scarce.

Remember that while WD-40 can be a helpful tool, it should not be relied upon as the sole solution for long-term survival. Always prioritize building your skills and knowledge, as well as having a well-rounded toolkit for a variety of situations.

My 2 Cents:

When using WD-40, be mindful of its limited shelf life. If you’re relying on it for survival purposes, it’s a good idea to periodically check and replace your stock to ensure its effectiveness.
