It’s the name the chemist who developed the product back in 1953 used, straight from his lab book. The chemist was Norm Larsen, working in a small lab in San Diego, California. He attempted to create a formula to prevent metal corrosion on rockets for the Aerospace industry. Norm’s persistence paid off when he perfected the formula on his 40th try.
WD-40 made its first appearance on the shelves in the USA in 1958. By 1960, an average of 45 cases were sold per day from the trunks of vehicles. By 1993, one million were being sold each week. And as a result, today, WD-40 is available in 187 countries worldwide!
WD-40 MULTI-USE PRODUCT FULFILS FIVE BASIC FUNCTIONS:
WD-40 Multi-Use product is a versatile solution for use at home, in a garage, or a factory. It’s a complex blend of lubricating oils, performance additives, surfactants and solvents which combine to deliver lubrication, water displacement, cleaning and rust protection on various metal surfaces. We can’t really tell you what’s inside as this is our best-kept secret, however, we can tell you what it doesn’t contain:
We manufacture WD-40® to a high degree of specifications. Therefore the product should continue to perform as expected for almost an indefinite period of time. However, actual performance is affected by the longevity of mechanical items such as the valve assembly on aerosol cans. As such, the shelf life is considered to be 5 years from the date of production; however, product will often dispense and perform as expected for considerably longer. You should store WD-40® between 4 and 54 degrees centigrade, and always shake before use.
