WD40 - The Original Maintenance Spray
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. It protects metal from rust and corrosion, penetrates stuck or jammed parts, displaces moisture, and lubricates just about anything. It is also great when it comes to cleaning grease, grime, and other marks from most surfaces.
