Understanding WD-40
WD-40 is a penetrating oil that has been a staple in many workshops and households for decades. Its name comes from the phrase “Water Displacement, 40th attempt,” which refers to the number of tries it took for the creator to develop a formula that could successfully displace water from surfaces. WD-40 is not a lubricant, but rather a penetrating oil designed to loosen stuck parts, protect metal from rust and corrosion, and displace moisture.
The Science Behind WD-40
WD-40 works by using a combination of solvents and oils to penetrate the microscopic spaces between surfaces. When applied to a stuck bolt, the solvents in WD-40 help to dissolve any rust, grime, or other substances that may be causing the bolt to stick. The oils in WD-40 then help to fill in the gaps between the threads, reducing friction and making it easier to turn the bolt.
Chemical Composition
The exact chemical composition of WD-40 is a trade secret, but it is known to contain a mixture of petroleum-based oils, solvents, and other additives. The main components of WD-40 include:
- Mineral oil
- Petroleum-based solvents
- Corrosion inhibitors
- Anti-wear additives
These components work together to create a formula that is both potent and versatile.
