If you don't have W40 in your house, you are hardly an American,
“Duct Tape Makes It Stop – WD40 Makes It Go.” Duct Tape & WD40 simbolize the staple in garages across America.
American fix anything can be fixed with duct tapes and WD40.
Read when you've got time to spare.
What can you do with a can of WD40? Lubricate M-16s, catch bigger fish, de-ice rod guides, clean turtles, repel pigeons, remove dog poo, make a flame-thrower, and much, much more.
If you could take the American spirit—equal parts Daniel Boone, Chuck Yeager, and Elon Musk—and distill it into an aerosol, it would be a blue-and-yellow can of WD40. A 1983 survey revealed that 4 in every 5 American homes had a can of WD40 in them. Among Field & Stream readers, that figure is probably 19 out of 20.
For more than 60 years, we’ve been relying on the 40th attempt of a Water Displacement formula to fix, well, whatever needs fixing. The WD40 website promotes dozens of uses for their product, as well as a list of 2,000 uses submitted by actual users. Some are genius. Some are just plain wacky. We have sprinkled our favorite 20 throughout this article, both from that list and from the body of popular lore that has arisen around the miracle spray. As surprising as any of them is the story of just how WD40 came to be, and how it became a staple in garages across America.
The story of WD40 begins in 1953, when the fledgling Rocket Chemical Company—all three employees—set out to create a line of rust-prevention solvents and degreasers for the aerospace industry. Working out of a tiny lab in San Diego, it took them 40 attempts to perfect a water-displacement formula. And so Water Displacement 40 came to be. An aerospace contractor named Convair first used the product to protect the outer skin of the Atlas Missile, which had external steel “balloon” fuel tanks that were so thin and delicate that they had to remain pressurized even when empty to keep from collapsing. Over time, Convair employees began sneaking the stuff home for their own uses. By 1958, the product was commercially available.
There have been all sorts of guesses about what exactly is in WD40, but the company isn’t saying. In 2009, Wired Magazine sent some to a laboratory to have it analyzed. The verdict? Fish oil, Vaseline, and “the goop inside homemade lava lamps.” Fact is, nobody knows. The formula has never been patented, apparently from fear somebody would find out. Instead, it’s a closely guarded trade secret locked up in a bank vault in San Diego.
By 1960, the company more than doubled in size, growing to seven people, and sold an average of 45 cases per day from the trunks of their cars to hardware and sporting-goods stores in the San Diego area.
The small-niche nature of the business began to change in 1961, when the first full-truckload order was occasioned by Hurricane Carla, which struck the U.S. Gulf Coast. Employees came in on a Saturday to produce extra WD40 to meet the needs of disaster victims, to recondition flood- and rain-damaged vehicles and equipment. Before long, it spread into American households and industry.
In 1969, the Rocket Chemical Company was renamed for WD40, which by then was its sole product. Early versions of the can show a rocket on the label. But by the time of the name change, it was long gone. It’s not just for rockets anymore. During the Vietnam war, packages containing the spray were being sent to soldiers to keep their finicky M-16s cycling.
