The WD-40 Trigger Pro non-aerosol multi-use spray contains 20 oz. of lubricant that can be applied to almost any item to reduce friction and protect metal from rust and other corrosion. With over 2,000 documented uses, WD-40 is also commonly used to loosen stuck metal parts, remove grease and grime, silence squeaky components, and displace water to remove moisture from electrical systems. Even after the lubricant has dried, it continues to protect surfaces from corrosion. The lubricant’s petroleum base permits use on most materials, excluding polycarbonate and clear polystyrene. It has a non-aerosol formula that also dissolves adhesives to remove stickers and labels, and allows the bottle to be recycled more easily than aerosol cans. The bottle contains 20 oz. of lubricant for moderate to heavy use and has a pump handle for control over the amount of lubricant dispensed. The nozzle offers both spray and stream options, and can rotate into the off position to prevent accidental release during storage. The nozzle has a child-resistant design that requires the user to push a tab before rotating the spray nozzle, and the closure also has a child-resistant design that cannot be opened, making it unable to be refilled.
Industrial lubricants can be found in most machinery performing one or more functions, including reducing friction and wear, preventing components from adhering to each other, distributing loads more evenly, dispersing heat away from moving parts, and preventing corrosion. Although many materials are used as lubricants, the most common are oil (also called fluid lubricants) and grease because of their versatility. Oil lubricants contain either a petroleum or synthetic base, the properties of which are modified by the addition of various additives. Grease lubricants, a mixture of oil lubricant and a thickening agent, have a thicker consistency than oil, enabling use wherever liquids cannot be retained and requiring less frequent changes.
WD-40 manufactures lubricants, and household and industrial cleaners. The company is headquartered in San Diego, CA.
