WD-40 Multi-Use Product is a world-renowned lubricant and penetrant essential for any trade or DIY toolbox. The 300ml Smart Straw version solves the common frustration of lost red straws. By utilizing the “Spray 2 Ways” system, users can flip the straw up for precision application in tight gaps—such as squeaky hinges or seized nuts—or flip it down for a wide-angle spray to coat larger surface areas for rust prevention.
The “WD” in WD-40 stands for Water Displacement. This formula is specifically engineered to drive out moisture from electrical systems and metal joints. By creating a protective barrier, it prevents oxygen and water from reaching metal surfaces, significantly reducing the risk of rust and corrosion in damp UK environments. As a penetrating oil, it seeps into microscopic gaps to break the bond between rust and metal, making it the go-to solution for freeing stuck bolts.
Whether you are maintaining heating system valves or fixing a stiff garden gate, the 300ml canister offers the perfect balance of portability and capacity. Its non-conductive formula is safe for use on electrical equipment (when powered off) to remove moisture-induced shorts and clean away stubborn grease, grime, and adhesive residue.

Nozzle Type: Smart Straw (Flip-up for Stream / Flip-down for Spray).
