Break the rust bonds that hold stuck parts together with our WD-40 Specialist Penetrant spray. It specifically targets corroded or rusted components and mechanisms. This powerful formula helps you loosens stuck or seized parts by targeting corrosion quickly and easily. The penetrant has an extremely low surface tension, meaning it can cut through rust, seams and tightly-bonded threads to easily saturate and lubricate seized fixings. The capillary action of the formula means it can help you reach tight and hard to reach spaces. Highly water resistant, WD-40 Specialist Penetrant can also displace moisture that may be disrupting smooth movement, and can be used as a preventative to prohibit the build up of rust and corrosion in the future.
Use in temperatures ranging from -20°C to +90°C, on materials such as metal, rubber, plastics, alloys and most paints.
