Penetrating Lubricant for Stuck Parts

WD-40 Specialist Rust Release Penetrant is a fast-acting lubricant formulated to loosen rusted or seized components. It penetrates deep into threads, crevices and seams to break the bonds holding stuck parts together. The aerosol spray is effective on nuts, bolts, screws, locks and chains. It is safe for use on plastics, rubber and metal surfaces.

Blu Torch Technology Upgrade

This specialist penetrant features Blu Torch Technology to deliver faster rust release compared to standard multi-purpose formulas. The upgrade is worth it when general-purpose lubricants fail to free heavily corroded or frozen assemblies. It leaves a protective layer that helps prevent corrosion from re-forming after application. The 11 oz aerosol can provides targeted delivery for maintenance and repair tasks.

11 oz Aerosol Capacity and Coverage

The 11 oz can supplies sufficient volume for multiple applications across automotive, industrial and household jobs. It comfortably handles routine freeing of stuck fasteners, hinges and moving mechanisms where corrosion has built up. The protective film extends the interval before rust reappears on treated parts. The pack of six cans ensures stock is available for ongoing maintenance schedules.

Questions about this item

Does the 11 oz aerosol can fit standard tool-belt loops or storage racks?

The 11 oz can is a typical aerosol size that slides into most universal tool-belt loops and standard workshop racks designed for spray cans.

How do I apply the penetrant so the Blu Torch Technology reaches deep threads, and what step is often missed?

Shake the can well, spray directly onto the rusted fastener, and let it soak for several minutes; the step many skip is allowing enough dwell time before trying to turn the part.

Will the protective layer left by this penetrant need re-application on outdoor chains and locks?

Yes, the corrosion-preventive film wears off with weather and friction, so respray chains, locks and other exposed parts periodically to maintain protection.
