Free up the bolt that just won't budge

Every garage has that one rusted nut or seized hinge, and this penetrating oil is made for exactly that job. It works its way along the metal and deep into threads and mechanisms, cutting through rust, corrosion and grime so stuck parts come loose. Once things are moving again, it doubles as a lubricant to keep them that way.

Why you'll love it

  • Loosens seized parts: cuts through rust and build-up on bolts, nuts and fasteners.
  • Creeps deep: formulated to travel along metal surfaces and into threads.
  • Lubricates: keeps chains, gears, hinges, rollers and slides running smoothly.
  • Protects metal: helps guard tools and metal parts while they're in storage.
  • All-round use: one product for the car, the boat, the workshop and the house.

Perfect for: rusty bolts on cars and bikes, squeaky gates and hinges, workshop tools, boat and garden machinery
