WD-40 Specialist Penetrant Smart Straw Rust Release Lubricant Spray 400ml

WD-40 Specialist Penetrant Smart Straw

WD-40 Specialist Penetrant is a professional-grade penetrating spray designed to quickly loosen rusted, seized and stuck components.

Its fast-acting formula uses capillary action to penetrate deep into tight crevices, threads and seams, helping break the bonds caused by rust and corrosion. It also leaves behind a lubricating protective layer to help prevent rust and corrosion from re-forming.

Ideal for use on nuts, bolts, pipe threads, fasteners and other rusted or seized parts. The low-odour formula is suitable for use on most common metals, plastics and rubbers when used as directed.

The permanently attached Smart Straw® Sprays 2 Ways® system allows precise application with the straw raised or a wider spray with the straw folded down.
