WD-40 is an all-purpose liquid for displacing moisture, corrosion control, lubrication, cleaning and penetration. It can 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.
