5-in-1 Protection Formula: Penetrates stuck parts, lubricates moving components, provides corrosion and rust protection for metal, while displacing moisture and cleaning surfaces, making the WD40 multi use spray your complete toolbox solution. Smart Straw Precision Control: Flip up for 2mm precision stream reaching deep into tight spaces or flip down for wide lubricant spray coverage, and with the permanently attached straw you'll always have perfect spray oil control. Cleans Without Attracting Dirt: Unlike ordinary maintenance spray, our formula removes grime while actively repelling dust buildup, making it the perfect squeaky door oil that keeps hinges clean plus essential bike lubricant. 450ml Professional Size: Ideal anti rust spray for metal maintenance and prevention, yet the WD-40 multipurpose lubricating spray excels at protection and lubrication rather than serving as a dedicated rust remover or light penetrating spray. Trusted Toolbox Essential Since 1953: Professional-grade light lubricant proven across 2000+ documented uses, and our original water resistant lubricant spray formula protects in temperatures from -45°C to 150°C for reliable performance. Not For Specialist Tasks: While excellent for general maintenance, this isn't a dedicated rust remover spray, heavy penetrating spray, bike chain oil, chain cleaner, or brake component lubricant; choose WD-40 Specialist for those specific needs.
