The 3-in-One Professional High-Performance Penetrant spray contains 11 oz. of penetrant that can be applied to components such as threads, nuts, locks, and chains that have been rusted together to release the rusted bond and protect the surfaces from future corrosion. The product also removes grease, grime, and other contaminants from a variety of surfaces. The 11-oz. aerosol can is sized for heavy use in commercial applications, and the detached straw inserts into the nozzle to create a precision stream of penetrant for controlled application.

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, as well as household and industrial cleaners, and is headquartered in San Diego, CA.
