RUST SHOCK is the powerful chemical wrench to help you remove rust and loosen stuck screw connections. RUST SHOCK performs where ordinary mineral oil based products fail, and where the screw connections so far could not be loosened other than mechanically (angel grinder, welding or cutting torches). RUST SHOCK penetrates rust, oil, carbon and grease which makes it ideal for every application where conventional rust remover fail. Its fast and effective performance is based on 2-fold function: when applied, RUST SHOCK generates a cooling and shrinking effect on the rusted or corroded parts. Combined with its high capillary penetration properties, the product can easily penetrate deeply even into the smallest gaps.
