Out of sheer helplessness I have this "Sonax Ultra quadruple KlimaCleanerzeux" ordered. And, although I had previously never heard of such a good "climate bomb". But what you should already here can go wrong? The attempt was worth it.
Completely Easy Application: Removing indoor / pollen filter, put air conditioning on cold, ventilation system to recirculation, seats fold forward ... and then with the engine running this bomb detonate in the rear footwell. Wait 15 minutes and then ventilate once all good !!
The first days smelled the car in pretty strictly for "Chemical warfare", but not unpleasant! Only you could not really judge whether the application has actually brought something at this time.
After this chemical smell was gone, what came out of the air conditioning? Correct: neutral, pleasant smelling air. And until now, the application is now produces about 2.5 months. The bacterial and microbial attack seems to me removed successfully!
Had I known that before, I would have saved myself a lot of money. So an application incredibly easy to repeat if necessary and not cost the earth. I would recommend the Power Cleaner Sonax full. Really had no great expectations, but the cleaner has convinced me !!
