A fast-acting penetrant with capillary action to penetrate deep into crevices, threads and seams to break the rust bonds that hold stuck parts together.
WD-40 Specialist® Penetrant is a fast-acting penetrant with capillary action to penetrate deep into crevices, threads and seams to break the rust bonds that hold stuck parts together. It is a low odor formula that works on contact to free rusted nuts, bolts, threads, locks, and chains leaving behind a protective layer that prevents rust and corrosion from re-forming.Use in temperatures ranging from -20°C to +90°C, on materials such as metal, rubber, plastics, alloys and most paints. With the Smart Straw applicator, you’ve got two ways to spray; use the flip up straw for hard to reach areas, such as inside chains, locks or rollers, then flip it down to use the wide angle spray eye for area coverage on surfaces.
