Originally created as a rust-prevention solvent for use in the aerospace industry, WD-40 has become the go-to product for your home’s squeaky door hinges and stuck bike chains (Which can be counter productive as it then traps dirt and dust inside.) There’s some debate about what the product actually is, however—and what it should be used for.
If you believe the WD-40 website, the popular household fix-it spray “is a unique, special blend of lubricants.” If you believe the rest of the internet, it is not really a lubricant; rather a degreaser and water-displacing solvent. (According to the brand, the name does stand for Water Displacement, 40th formula.”) In addition to the lubricants it purportedly contains, it also has anti-corrosion agents and ingredients for “penetration and soil removal.”
Regardless of where you stand on its fundamental constitution, it’s hard to deny the product has a lot of practical uses around the house and garage—many that the average consumer of WD-40 may not be aware of. Without further ado, let’s get into some of the lesser-known ways it can aid your everyday life.
