What is wd-40?

WD-40 literally stands for Water Displacement, 40th formula…

That’s the name straight out of the lab book used by the chemist who developed the product back in 1953. The chemist, Norm Larsen working in a small lab in San Diego, California, was attempting to concoct a formula to prevent metal corrosion on rockets for the Aerospace industry, a task which is done by displacing water. Norm’s persistence paid off when he perfected the formula on his 40th try.

WD-40 made it’s first appearance on shelves in USA in 1958 and by 1960 an average of 45 case were sold per day from the trunk of vehicles. By 1993, one millions were being sold each week and today is available in 187 countries worldwide!

What is the shelf life for WD-40 Multi-Use-Products?

WD-40® is a product of persistent nature which is designed and manufactured to a high degree of specifications. The product should continue to perform as expected for an almost 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. WD-40® should be stored between 4 degrees centigrade and 54 degrees centigrade, and always shaken before use.
