300004 LUBRICANT PENETRATE WD-40 11OZ

Overview

WD-40 Specialist Rust Release Penetrant Spray (300004) is designed for hardware and building consumables applications requiring deep-penetrating lubrication and rust release on seized or corroded fasteners and components.

Technical Features

• Blu Torch Technology formulation — a proprietary blend of synthetic additives that rapidly penetrates deep into crevices, threads, and seams to break the bonds holding stuck parts, reducing downtime when freeing seized fasteners.
• Protective residual layer — after penetration, the formula leaves a protective coating that inhibits rust and corrosion from reforming, extending the service life of treated components.
• 50-State VOC compliant — meets volatile organic compound regulations across all U.S. states, allowing use on job sites and in facilities with strict environmental compliance requirements.
• Broad material compatibility — safe for use on plastics, rubber, and metal, making it applicable across a wide range of assemblies without risk of material degradation.
• Spray delivery format — pressurized 11 oz can with spray applicator enables targeted delivery into tight crevices, threads, and seams where brush or liquid application is impractical.

Applications

• Freeing rusted or seized nuts, bolts, and threaded fasteners on structural and mechanical assemblies.
• Penetrating corroded locks and chains to restore operation without disassembly.
• Preventive treatment on metal components exposed to moisture, salt, or outdoor conditions to resist future rust formation.
• General maintenance use on mixed-material assemblies where compatibility with plastics and rubber is required.
