After I have also tried a few remedies, I ended here on this page. This product I knew beslang not and I was quite tired of the advertising promises. We have also in the bathroom this problem and I did not think after a few failures to the great effect of Mellerud mold-shredder. When I received the Podukt I was very skeptical. The much described chlorine odor struck me, but I do not really promised me a lot of product. So I turned to this. Soaked in the bathroom, the nasty black points that had made themselves comfortable in the silicone joints of the shower. Sprayed everything a well and left the bathroom for about an hour. A chlorine smell exuded from the bathroom, despite the window open and I was curious about the result. After an hour I got myself then rag and bucket, so I set to scrubbing's me and went back into the bathroom. It struck me at the sight almost the bucket out of hand .. Where were the black spots? NOTHING, absolutely nothing was to see more! I can only agree with all the previous speakers, this product is really worth the money! Every time I would recommend it to anyone for effective mold control.
