Product details

WD-40 Specialist® Penetrant is a fast-acting, low-odor formula engineered with deep capillary action to penetrate crevices, threads, and seams to rapidly break the toughest rust bonds. This powerful solution works on contact to free seized nuts, bolts, and locks while leaving behind a protective layer that prevents rust and corrosion from re-forming. Equipped with the versatile Spray 2 Ways® technology, it allows you to toggle between a precision stream and a wider spray to blast through roadblocks in plumbing, auto maintenance, and fabrication shops.

Features & Benefits

  • Deep Capillary Action: Specifically designed to penetrate deep into threads and seams on contact, breaking the bonds that hold stuck parts together in minutes.
  • Spray 2 Ways® Delivery: Features a versatile nozzle that flips up for a pinpoint stream and down for a wider spray, providing customizable application for any task.
  • Long-Term Corrosion Barrier: Frees rusted components while simultaneously depositing a protective shield to block moisture and stop rust from returning.
  • Industrial & Home Efficiency: A low-odor, high-performance tool that increases productivity in fabrication shops and simplifies difficult plumbing or DIY projects.
