WD-40 Specialist Rust Penetrant is a fast-acting penetrant that gets deep into crevices, threads, and seams to break the bonds that hold stuck parts together. WD-40 Specialist Rust Release Penetrant Spray quickly goes to work on rusted nuts, bolts, threads, locks and chains, and also leaves behind a protective layer to help prevent rust and corrosion from re-forming. Containing Blu Torch Technology, a proprietary blend of synthetic additives, it is safe to use on plastics, rubber, and metal.
- Extra-penetrating Blu Torch technology
- Ideal for use on nuts, bolts, threads and locks
