WD-40: What the penetrating oil is useful for

Every do-it-yourselfer knows the blue-yellow spray bottle with the red cap: It is the all-rounder WD-40, which should not be missing in any workshop. Others may use the German competing product "Caramba", but most swear by the US penetrating oil.

WD-40: What's behind the penetrating oil?

WD-40 is a silicone-free multifunctional oil that is now sold in more than 160 countries around the world. Developed as a helper for industry and trade, the oil with its many good properties soon made itself indispensable. Over time, hobbyists and tinkerers discovered this "liquid tool" for their hobby and for the workshop. It has even proven itself in the household.

The name of the WD-40 stands for "Water dispersant, 40th formula", in German roughly "Wasserverdrängung, 40th formula". Incidentally, it is not a lubricant, as is often wrongly assumed, but a means of displacing water and protecting metals from corrosion.

It was developed in the USA in the 1950s and initially used in the missile industry. Many engineers secretly took the all-purpose product home with them, and after a short time it was also on the shelves of the retail trade. The WD-40 was also used rather ingloriously during the Vietnam War, when weapons were cleaned with it. Today it is used in workshops and households and is irreplaceable for many areas of application.
