WD-40 Specialist® Penetrant

WD-40 Specialist Penetrant contains a proprietary blend of ingredients that work fast to free rusted bolts and other stuck parts. The capillary action penetrates into tight crevices, threads, and seams to break the bonds that hold stuck parts together. It helps prevent rust and corrosion from re-forming and leaves behind a lubricating layer. The professional-grade formula is low odor, working effectively without harsh, lingering scents.

Use Penetrant on nuts, bolts, pipe threads and rusted things that are stuck and won't move! It is safe to use on most common application surfaces, including most metals, plastics, and rubbers when used as directed. If unsure, test on a small area first.

The permanently attached Smart Straw® Sprays 2 Ways® delivery system allows for pinpoint application or a wider spray, giving you different options to fit the job.
