WD-40

WD-40 is a well-known American brand associated with maintenance chemicals for automotive, industrial, household and workshop use. Its name is most closely linked to the original WD-40 Multi-Use Product, a water-displacing spray widely used to loosen stuck fasteners, help protect metal surfaces from moisture, reduce squeaks and assist with general cleaning and light lubrication tasks. The brand is also associated with specialist sprays such as penetrants, silicone lubricants, contact cleaners, degreasers and other service products used around vehicles.

For car owners and technicians, WD-40 products are typically used during repair and maintenance rather than as replacement mechanical parts. They can be helpful when working on corroded bolts, hinges, locks, battery terminals, electrical connectors, tools, brackets and other areas where moisture, grime or seized components make service more difficult. Choosing the correct WD-40 product depends on the task: a penetrant for stuck hardware, a contact cleaner for electrical service, or a degreaser for cleaning oily components.
