WD-40® Specialist® Rust release penetrant spray penetrates deep into crevices, threads and seams to break the bonds that hold stuck parts together. Our 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. It is 50-state VOC compliant and safe to use on plastics, rubber and metal.
