WD-40 Smart Straw 450ml delivers professional-grade protection and performance in a single aerosol. The innovative 360° valve enables upright or inverted spraying, adapting to any application without compromise. Its Smart Straw technology produces a wide, precise spray pattern for controlled coverage across surfaces and into tight spaces. This multi-purpose formula penetrates seized components to free stuck parts, lubricates moving equipment for smooth operation, and displaces moisture to safeguard electrical systems from corrosion. It effectively removes accumulated oil, dirt, grease and grime whilst forming a protective barrier against rust and oxidation on metal surfaces. Ideal for maintenance, repair and restoration work across industrial, automotive and domestic settings.
