BOLL rust remover - rust shock - spray

Facilitates the loosening of rusted and seized bolts, nuts, spark plugs, and other metal parts. By instantly cooling the surface down to -40°C, it causes micro-cracks in the rust structure, which, combined with mineral oil of excellent penetrating properties, allows even heavily corroded connections to be effectively loosened. The addition of graphite provides extra lubrication, protecting components from seizing again. The product leaves a thin protective layer on the surface, safeguarding the metal against moisture and atmospheric effects.
