Known as the can with 1,000 uses, WD-40® is a prepping survival tool! If you haven’t started stocking WD-40®, you definitely should have some of it in your prepping arsenal. While there are a variety of ways to use this stuff, we are sticking to the reasons why this miracle can be something preppers should stock! 

What is WD-40®?

It’s a Multi-Purpose Lubricant that reduces friction, displaces moisture, removes grease and grime, and protects metal from rust and corrosion. It’s kind of like this miracle sauce that is effective at doing a lot of different things. Because of this, WD-40® is something you definitely want to have!

Alice, an awesome follower told me about the 3-ounce WD-40® Cans!!!!

A Little History

Did you know that it took 40-attempts to get this water displacing formula to work?! A small lab in San Diego, California, set out to create a line of rust-prevention solvents and degreasers to use in the aerospace industry, and it took them 40 tries to get it right!

On the 40th attempt, this small lab got it right and in a big way! In fact, its name literally stands for Water Displacement, 40th formula hence, WD-40®. It was originally only used commercially. The first to use it was Convair. They used it to protect the outer skin of the Atlas Missile from rust and corrosion. 

WD-40 worked so well for this aerospace contractor that several employees snuck cans of it in their lunchboxes to use at home. A few years later, Rocket Chemical Company founder, Norm Larsen, experimented with putting WD-40® into aerosol cans, and WD-40® was brought to consumers everywhere! 

Prepper Tip: If it moves and shouldn’t use super glue or Duct Tape. If it doesn’t move and should, use WD-40®!

  • Generators
  • Power panel boxes
  • Other electrical connections

To wick away moisture on electrical equipment, ensure the power is turned off and everything is unplugged. Spray it on anything electrical to wick away moisture and preserve your equipment. 

Stock WD-40® For Fishing Equipment

Some fishermen swear there’s fish oil in WD-40®, and that’s because they say it helps them catch more fish! Although that isn’t true, it does work its magic at keeping fish hooks and lures clean. 

When it comes to a DISASTER scenario, fishing may be your only way of getting food. If that’s the case, you will want to make sure to keep your hooks and lures in tip-top condition since you may not be able to buy more. A can of WD-40® works wonders for this. 

Stock it For Prevention and Maintenance

As stated earlier, this stuff is great at removing rust.  Additionally, it can keep things from getting rusty in the first place. Here are a few ways you can use it for maintenance:

  • Remove rust from things like screws, nuts, bolts, and plumbing joints. 
  • Unfreeze a lock that won’t open. 
  • Spray it on all your tools to add a layer of protection and prevent them from rusting. 

Stock WD-40® for the Garden and Outdoor Tools

Let’s face it; your garden tools are essential in making sure you have the food that you need. If A disaster hits, you may not be able to run to Walmart and get a new tool. WD-40® is a great way to keep your garden tools and hand tools in pristine working condition. 

  • Spray it on your shovel to help you dig more effectively. Dirt and clay will just slide off. Additionally, it helps keep your shovel from rusting. 
  • Use it to clean your pruning shears and garden tools. WD-40 prevents blades of all kinds from rusting and keeps your tools in pristine condition.

What Should You NOT Use It On?

Although WD-40® can be used for almost anything, there are a few things you shouldn’t use it on. Here are a few things you shouldn’t use WD-40 on:

  • Paintball guns– WD-40® will melt the seals in the guns, so you don’t want to use it for that at all. 
  • Firearms– Never use it to clean or maintain firearms. WD-40® is hygroscopic which means it can attract moisture to the firearm resulting in rust. 
  • Gears– WD-40® isn’t really a lubricant. It can be useful at getting things unstuck, but you should use gear lubricants not WD-40®. 
  • Things you want to keep clean– It attracts dust and dirt, so if you want something to stay clean, you probably shouldn’t use WD-40®. 
  • Phones, Tablets, iPads etc– Don’t use it on your computers. If it gets inside the electronics, it can damage the plastic parts inside. 

How to Store WD-40®

A can of this magical stuff has a shelf life of 5-years, but will often dispense and perform for much longer if stored properly. You want to store your WD-40® in a cool, well-ventilated area away from combustible materials.

It’s suggested to not store them in the garage due to the gas and other possible combustibles. Consider a shed if protected from fuels and if kept below extreme heat. You don’t want it to be in direct sunlight or reach temperatures above 120℉ or below freezing.

  1. Linda,

    Superb post. I know a lot about WD-40 but even I didn’t know all of this about it. Well done.

    Oh, about those garden tools. If they have wooden handles treating the handles with food grade mineral oil helps preserve them.

  2. Linda, I Love, love, love this info! I really liked learning how it came to us consumers. Lol, I immediately went into my son’s room and told him I learned a way for us to get bug splatter off our truck’s windshield. It’s gonna be 42 degrees here tomorrow so I can clean the windshield and leave a bit of it on for snow/ice too. I use wd40 for a lot of things but you just educated this old girl on a lot more uses. Thank you!

  3. Somebody once gave me a very small 3 ounce can of WD-40 as a joke and it’s the perfect size to keep handy in a small kit, along with a travel size bit of duct tape. Graphite lubricant is another handy item, especially for sticky locks. Can be very messy though.

  4. If you have an can that looses its airesol (hate wasting a half can), take a flat tip screwdriver and pry the top, quarter size crimp away from the main bottle being careful not to tip the can. you can then put the contents in an unused spray bottle for use. I think you can still buy WD in a gallon can to use that way as well. As stated, it is Not an oil and won’t last as long as oil. So once you get things broken free, oil them properly. Also use WD on grease stains as a prewash for clothing.

  5. We always have WD-40 in our garage. My husband uses it for everything. He sends me outside if he has to use it on something in the house because you know I am allergic to it. :”Allergic to modern life as one DR. told me” I was once told that it would help with stiff joints but you know why I don’t try it that way but I have friends who swear by it.
