About WD-40
WD-40 — the world’s legendary multi-use spray
WD-40 is more than just a lubricant. It is a world-famous multi-purpose technical spray trusted for over 70 years. Originally developed in the United States in 1953 by engineer Norman Larsen for the Rocket Chemical Company (San Diego, California), WD-40 was created to displace moisture and protect metal from corrosion.
Today, WD-40 is a global symbol of reliability, found in garages, workshops, homes, and industrial facilities. The brand’s products are sold in more than 160 countries worldwide.
What does WD-40 mean?
The name WD-40 stands for Water Displacement — 40th Attempt. After 39 unsuccessful trials, the engineers finally perfected the formula on the 40th try. This unique composition remains a closely guarded trade secret and has never been patented to avoid disclosure.
WD-40 was first used by Convair to protect the outer surfaces of Atlas rockets from corrosion. Its exceptional performance led to widespread use beyond aerospace applications, and by 1958 WD-40 was introduced to retail markets.
5 key functions of WD-40
- Displaces moisture — protects metal and electrical components from water and condensation;
- Prevents corrosion — creates a protective barrier against rust;
- Penetrates — loosens stuck and rusted parts;
- Lubricates — ensures smooth operation without sticky residues;
- Cleans — removes grease, grime, adhesive residues and more.
Why choose WD-40?
The main advantage of WD-40 is its versatility. One single product replaces multiple solutions: lubricant, cleaner, corrosion protection and moisture displacer. It contains no silicone, does not leave sticky residues and does not attract dirt or dust.
WD-40 is widely used for:
- cars, motorcycles and bicycles;
- garages, workshops and service stations;
- household tasks — locks, hinges, tools;
- industrial, electrical and maintenance applications.
