Job Done Right | WD-40

WD-40 SpecialistĀ® Penetrant

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. Now the job is even easier with our proprietary 8” flexible straw that bends and keeps its shape, allowing unlimited access to hard-to-reach places.
