WD-40 300004 Details

Blast away rust and corrosion with WD-40 Specialist rust release penetrant spray! This powerful lubricant comes in a convenient 11 oz. bottle with built-in Smart Straw - simply flip the straw up to direct a precision stream onto small areas, or flip the straw down for a wider regular spray.

WD-40 Specialist rust release penentrant spray boasts Blu Torch technology, a special blend of synthetic additives that breaks down rust on nuts, bolts, threads, locks, chains, and other plastic, rubber, or metal parts. The spray penetrates into crevices, threads, and seams to break down the bonds causing parts to stick and leaves behind a protective layer to help prevent new rust or corrosion from forming. It is VOC compliant in all 50 states.
