WD40 Universal Lubricant & Rust Preventive is a liquid that serves functions of cleaning, dehumidifying, lubricating, and penetrating to remove rust. It was developed by chemist Norm Larsen in 1953; it can solve the problem of components sticking together due to rust caused by moisture, and it also has rust-preventing properties.
WD-40 is a universal maintenance product for metal items; it is an organic mixture that offers six functions: rust prevention, moisture removal, rust dissolution, lubrication, cleaning, and electrical conductivity.
WD-40 is a universal rust preventive oil. Literally, it stands for “Water Displacement, 40th attempt” – the W in WD-40 represents water, D represents elimination, and 40 represents the 40th attempt. * The name WD-40 comes directly from the terms used in the research notes of the chemists who developed WD-40 in 1953. At that time, chemist Norm Larsen (1923–1970) tried to develop a formula that could prevent corrosion by removing moisture and humidity. After 40 attempts, Norm, through perseverance and relentless effort, was finally rewarded by completing the invention.
