Silverhook Freeze Spray is ideal for releasing seized nuts, screws, split pins, rusted joints, and hinges, etc. The unique formulation of Freeze Spray will freeze the offending item as low as -40°C. The resulting thermal stress causes microscopic cracks in the rust layer, allowing the specially formulated Mineral Graphite Oil to penetrate the joint and rust, making the releasing process easier. Silverhook Freeze Spray will also lubricate the parts which will help prevent future corrosion.
