Product Details

Break the rust bonds that hold stuck parts together with our WD-40 Specialist Penetrant Spray. This product is specifically designed to target corroded or rusted components and mechanisms. Its powerful formula effectively loosens stuck or seized parts by quickly addressing corrosion. Featuring an extremely low surface tension, the penetrant easily cuts through rust, seams, and tightly bonded threads, allowing it to saturate and lubricate seized fixings. The capillary action of the formula enables it to reach tight and hard-to-access spaces, making it an ideal solution for your needs.
