We all know it, this famous multi-purpose problem solver. It is said that 4 out of 5 households has a can or 2 around the house. WD-40 was created in 1953 by the Rocket Chemical Company.
It took them 40 attempts to get the water displacing formula worked out. But they must have been really good, because the original secret formula for WD-40®—which stands for Water Displacement perfected on the 40th try—is still in use in many households and companies today. In 1969 the company was renamed after its only product, WD-40 Company, Inc.
