WD-40® Multi-Use Smart Straw Aerosol – 450 ml

WD-40® Multi-Use Smart Straw (450 ml) is a versatile, all-purpose maintenance fluid designed to clean, lubricate, protect and free moving parts across a wide range of applications. Trusted worldwide, WD-40® is ideal for displacing moisture, preventing corrosion, loosening stuck components and removing grease, grime and residue from most surfaces. Product code: W/D44137S.

Although not primarily a lubricant, WD-40® is widely used on light machinery, tools and electrical equipment to improve performance and extend service life. Its unique formulation penetrates deep into metal surfaces and grain boundaries, offering reliable protection without damaging fabrics, rubbers or plastics.

Supplied in a Smart Straw aerosol, this can features a permanently attached dual-action spray system. Flip the straw up for precise, targeted application, or flip it down for wide-area coverage — all with one hand and no loose straws to lose.
