WD-40 490027 Specialist Rust Release Penetrant Spray 11 oz

The WD-40 490027 is an 8-ounce aerosol can of the legendary multi-use formula equipped with the innovative Smart Straw delivery system. The permanently attached straw sprays lubricant two ways—flip it up for a precision stream to target tight spaces, or flip it down for a wide spray pattern to cover larger areas.

Five Essential Functions:

• Protects metal from rust and corrosion
• Drives out moisture and quickly dries out electrical systems to eliminate moisture-induced short circuits
• Frees sticky mechanisms, loosens rust-to-metal bonds and helps release stuck, frozen or rusted metal parts
• Removes grease, grime, gunk, gum, tar, sap, super glue, sticker residue, and other sticky stuff from multiple surfaces
• Lubricates moving parts such as hinges, wheels, pulleys, rollers, chains, and gears

The Smart Straw design eliminates lost straws and provides versatile application options for everything from precision work on tools and electronics to general maintenance around the home, garage, or shop. This light amber formula is non-conductive when dry, making it safe for use around electrical components.
