WD-40® Rust Release Penetrant Spray
WD-40® Rust Release Penetrant Spray penetrates deep into crevices, threads and seams to break the bonds that hold stuck parts together. The penetrating lubricant also leaves behind a protective layer and helps prevent rust and corrosion from re-forming. Containing Blu Torch™ Technology, a proprietary blend of synthetic additives, our rust remover spray quickly goes to work on rusted nuts, bolts, threads, locks and chains. WD-40 Specialist Rust Release Penetrant Spray frees rusted parts 50% faster than the leading competitor. It is 50-state VOC compliant and safe to use on plastics, rubber and metal.
