I have a door to the Schimmelvernichter sprayed to leave for the agent. When I came to the actual cleaning after one hour exposure with sponge and brush, no mold was visible. Nothing more. Admittedly, the destroyer seems to be a very powerful tool, it smells very strongly of chlorine and you should really use it with gloves. And protect eyes when sprayed on the ceiling!
Especially after intensive application you have to ventilate! There are also a means of Mellerud without chlorine, but with Ökotest "very good" ;-). It can avoid you if a strong chlorine smell does not please.
The Schimmelvernichter is a product with a super effect that persists longer and persistent, long-infested areas clean. Recommendation from me!
