WD-40 Specialist Penetrant Spray is a 400ml professional-grade rust penetrating oil designed to rapidly free rusted nuts, bolts, hinges, and locks. Its low surface tension formula penetrates deep into corroded joints, while the integrated Smart Straw offers precise application in any orientation. Safe on multiple materials and effective from -20°C to +90°C, it also deposits a water-resistant barrier to prevent future corrosion, making it the go-to solution for mechanics, engineers, and industrial maintenance.
