WD40familiene

WD-40 family refers to a line of products manufactured by the WD-40 Company, designed for moisture displacement, corrosion protection, and lubrication of metal parts and mechanical equipment. The flagship product, WD-40 Multi-Use Product, is widely used as a versatile solvent, rust preventer, and light lubricant, helping to loosen stuck parts, displace moisture, and protect metal surfaces from corrosion. The exact formulation is proprietary, but the product is generally described as a light hydrocarbon-based spray with a thin protective film.

Origin and naming are tied to the product’s intended purpose. WD-40 stands for Water Displacement, 40th formula, reflecting its development in the mid-20th century by a company originally focused on protecting aerospace components from moisture and corrosion before it reached broad consumer use. Over time, the WD-40 brand expanded beyond the original spray to a broader product family.

Product family and variations include the WD-40 Specialist line, which targets professional and industrial applications with penetrants, rust removers, and degreasers. The company also markets variants aimed at specific markets such as automotive, marine, and cycling, often marketed under separate product names but aligned with the core WD-40 functionality. These products share the common goal of displacing moisture, reducing friction, and protecting metal surfaces, while offering formulations tailored to different use cases.

Safety and usage notes emphasize that WD-40 is flammable and intended for use on metal and non-electronic surfaces. It is not a substitute for heavy-duty lubricants in high-load, high-temperature, or long-term bearing applications. Users should follow label directions, test on sensitive plastics or rubbers when needed, and avoid spraying on energized electrical equipment or sources of ignition.
