The WD-40 300ml multi-purpose lubricant is used for displacing moisture, corrosion control, lubrication, cleaning and penetration. It can penetrate the minute grain boundaries on all the metals. It protects the metal from rust and corrosion, penetrates stuck or jammed parts and lubricates it. It is also useful for cleaning grease, grime and other marks from most surfaces. This product is a mixture of chemical concentrates suspended in a high-grade petroleum distillate. It will not affect fabrics, rubbers or plastics.
