The special composition of the active ingredient creates a temperature shock to over -30 °C. The extreme cooling causes micro-fine cracks to form on the sealing ring of the injector, allowing the active ingredient to penetrate faster and deeper into the rust structure. Special additives ensure that the Caramba High-Performance Injector Special Solvent infiltrates rust crystals and moisture and breaks the bond between the rust layers. The sliding-active PTFE particles ensure good sliding properties and make it easier to remove the injectors.
Spray Caramba Injector Special Solvent generously and directly (with spray tube) on the seat (sealing ring) injector/engine. Then allow to react for approx. 30-45 minutes. Remove loosened dirt with the aid of compressed air and repeat the process several times at intervals of 5 minutes, as required. In the case of stubborn rust, leave to act overnight.
