High-quality rust remover with cracking effect due to extreme cooling and excellent creep properties

Cracking effect

  • By cooling the material surface, e.g. on a stud bolt, down to -40°C, micro-fine cracks appear in the corrosion layer at the connection points. These crack open the rust, ensuring better penetration of the active agent.

Excellent capillary action

  • In conjunction with the cracking effect, optimum creep properties ensure excellent rust penetration

Optimum rust removal

  • Quickly penetrates rust and loosens seized screws

  • Heavily rusted screw connections are loosened without damage

Corrosion protection additives for optimum protection

  • Provides lasting protection against further corrosion

Resin-free and acid-free


Suitable for use with rubber and seals

  • Remove excess material or splashes immediately from sensitive and painted surfaces.

  • Resin- and acid-free

  • Silicone-free
