Valve Cleaning with TUNAP Valve Clean Technology

Clean Valves without Dismantling

Valve Clean Technology enables quick and easy valve cleaning without removing the cylinder head. With the microflex® 933 valve cleaning granulate, contaminated or coked valves are cleaned or blasted with compressed air without leaving any residues or damage. At the same time, detached impurities and used granules are sucked off. Possible residues and coking are then dissolved without residue using the microflex® 936 neutralization solution.

Valve Cleaning in a Direct Comparison

Contaminated Valves: Problems, Causes and Solutions


Loss of performance, increased fuel consumption and rough idling are symptoms of valve deposits and contamination. The cause is a combination of exhaust gas recirculation and crankcase ventilation and lack of the physical flushing effect of fuel in direct injection systems.


Unfavourable driving habits such as frequent short trips and stop and go traffic together with increasing bio ingredients in fuel worsen matters.


Quick cleaning instead of hours of disassembly work: the new TUNAP Valve Clean System efficiently removes valve deposits and saves motorists four figure sums.
Notes on dirty or coked valves

Process of TUNAP valve cleaning

Process of TUNAP valve cleaning

  • The intake manifold and attachments are dismantled
  • Valves are irradiated and cleaned with the cleaning granulate
  • Used granulate and impurities are sucked off
  • Residues and coking are dissolved with the neutralization solution
Optimal cleaning result

Optimal cleaning result

The impact of the granulate releases the surface tension of the deposits on the inlet valves and the surrounding ducts. The coking and dirt are gently loosened without damaging the valves or even damaging the engine.

The TUNAP valve cleaning not only leads to an optimal cleaning result, it is also health-friendly and does not contain any allergy-causing substances.
