WD-40 Specialist Fast Release Penetrant 300g – 21014
Free up rusted bolts, seized screws, and corroded fixings fast with WD-40 Specialist Fast Release Penetrant, a rust-penetrating spray built for workshop and industrial use. Its low surface tension formula lets it quickly penetrate into seized mechanisms and fixings, working its way into tight crevices, threads, and seams to break the corrosion bonds holding stuck parts together. It's also highly water repellent, helping prevent further rust from forming after use.
Suitable for use on metal, alloys, rubber, and plastic, this penetrant is a genuine problem-solver for nuts and bolts, hinges, chains, bearings, locks, and fastenings that have seized up from rust or corrosion, making disassembly and repairs faster and safer without forcing or damaging components.
Fitted with a Smart Straw applicator, it gives you two ways to spray: flip the straw up for a precision stream that reaches tight, hard-to-access spots, or fold it down for a wider spray pattern to cover larger surface areas in one pass.
Key Features:
Fast-acting rust penetrant for seized and corroded parts
Low surface tension for deep penetration into threads, crevices, and seams
Water repellent formula helps prevent further corrosion
Suitable for metal, alloys, rubber, and plastic
Smart Straw applicator: precision stream or wide spray

Usage Tip: For badly seized fixings, apply the penetrant and allow a few minutes of dwell time before attempting to move the part, this gives it time to work into the corrosion and loosen the bond.
