Known as "the can with thousands of uses," WD-40 protects metal from rust and corrosion, penetrates stuck parts, displaces moisture, and lubricates just about anything. WD-40 is also great when it comes to removing grease, grime, rust, and other marks from most surfaces.
THE FIVE BASIC FUNCTIONS:
LUBRICATES: WD-40's lubricating ingredients are widely dispersed and hold firmly to all moving parts.
REMOVES: WD-40 gets under grease, grime, and gunk. WD-40 non-aerosol formulas also dissolve adhesives, allowing easy removal of labels, tape, stickers, and excess bonding material.
PROTECTS: WD-40 protects metal surfaces with corrosion-resistant ingredients to shield against moisture and other corrosive elements.
PENETRATES: WD-40 loosens rust-to-metal bonds and frees stuck, frozen or rusted metal parts.
DISPLACES MOISTURE: Because WD-40 displaces moisture, it quickly dries out electrical systems to eliminate moisture-induced short circuits.
