Rust Penetrant & Cleaner Spray with Flexible Straw | WD-40

WD-40 Specialist Penetrant with EZ-Reach 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.

Now the job is even easier with EZ-Reach, the permanently attached 8-inch flexible straw that bends and keeps its shape, giving you unlimited access to hard-to-reach places.

Use Penetrant with EZ-Reach on hard-to-reach 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.
