WD-40 Specialist Fast Release Penetrant Spray, 250ml, Rust Penetrating Oil Spray for Loosening Rusted Nuts & Bolts, Hinges, Locks, and Gears, Rust Prevention, Smart Straw Included

Penetrating Oil for Rust: The low surface tension formula penetrates deep into rusted threads and corroded joints, rapidly freeing seized bolts, nuts, and fixings where general-purpose sprays fail, the professional's choice from WD-40 Specialist.

Multi-Surface Rust Release: Loosens rusted hinges, stuck locks, and stiff chains while safe for use on metal, stainless steel, titanium, rubber, plastic, and PVC, performing reliably from -20°C to +90°C.

Lasting Corrosion Protection: Deposits a water-resistant barrier that delivers anti-rust and corrosion protection to guard bearings, pipes, conveyor belts, and exposed fixings against future build-up to extend service intervals between maintenance.

Professional-Grade Performance: Engineered for mechanics, engineers, and professionals who demand consistent results, this industrial-strength penetrating spray operates across a wide temperature range for workshop, garage, and field applications.

Precision Smart Straw Control: Reach tight spaces and awkward angles with the integrated Smart Straw for pinpoint accuracy, or flip down for broad coverage, the 360° valve enables spraying in any orientation, reducing product waste and time.

Specialist Maintenance System: Pre-clean with WD-40 Specialist Degreaser spray, apply Penetrant spray to free seized components, then protect with White Lithium Grease for lasting lubrication, or add Cutting Oil for drilling and metalwork.
