The WD-40 multi-use spray contains 5.5 oz. of lubricant that can be applied to almost any item to reduce friction and protect metal from rust and other corrosion. 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. The aerosol canister contains 5.5 oz. of lubricant and is sized for portability. Its nozzle dispenses the lubricant in a fan spray for quick application over large areas. The detached straw can be inserted into the nozzle to create a precision stream of lubricant for controlled application and fastens to the notched cap for secure storage when not in use.
