Since we had the mattress lying on the floor, and the room was also newly renovated, has already been made in a few days mold. Since I've never had anything to do until the time with mold, I acted out of panic and stuffed the respect of the same mattress in the washing machine. For safety, I have to mold remover also bought. But that was unfortunately in vain! I have the stuff on it sprayed, trying to rough - and because nothing went out, I got the whole thing again in the washing machine. One was a little bit better. So, I guess this spray remover directly onto the mold, do not wash before !!! Otherwise the sprayer would certainly worked better. 4 stars because it just yet smells like chlorine. From because chlorine free, but I finds not all that bad. Solang is the mold removed.
