WD-40 and other lubricants work by reducing friction between two surfaces. When two surfaces rub against each other, they create friction, which generates heat and can cause wear and tear on the surfaces. Lubricants like WD-40 contain a mixture of oils and other substances that help to reduce friction between the surfaces, making them slide against each other more smoothly.
WD-40 also contains solvents that help to dissolve dirt and grime, which can cause friction and make it harder for things to move smoothly. When applied to a surface, the solvent in WD-40 helps to loosen and remove any dirt or debris that may be present, allowing the lubricant to do its job more effectively.
In addition to reducing friction, WD-40 and other lubricants also help to protect surfaces from rust and corrosion. They form a thin film over the surface that helps to prevent moisture from reaching the metal underneath, which can cause rust and corrosion over time.
Overall, WD-40 and other lubricants work by reducing friction, removing dirt and debris, and protecting surfaces from rust and corrosion, all of which help to prolong the life of the equipment or machinery being lubricated.
