WD-40 is an all purpose liquid for displacing moisture, corrosion control, lubrication, cleaning and penetration. It has the ability to penetrate the minute grain boundaries on all metals.
Although not essentially a lubricant, WD-40 is regularly used to lubricate all light machinery and electrical equipment. WD-40 protects metal from rust and corrosion, penetrates stuck or jammed parts, displaces moisture, and lubricates just about anything. WD-40 is also great when it comes to cleaning grease, grime, and other marks from most surfaces.
WD-40 is a mixture of chemical concentrates suspended in a high grade petroleum distillate. It will not affect fabrics, rubbers or plastics. Its working temperature is between -100° F and +500° F.
Thoroughly recommended to clean, preserve and protect all tools.
The Five Basic Functions:
CLEANS: WD-40 gets under dirt, marks and grease, making it easy to wipe them away. It also dissolves adhesives, allowing the easy removal of labels, tape, and stickers.
PROTECTS: WD-40 protects metal surfaces with corrosion-resistant ingredients to shield against moisture and other corrosive elements.
LUBRICATES: WD-40's lubricating ingredients are widely dispersed, and hold firmly to all moving parts.
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. (Remember to turn the power off before you spray).
