Best results thanks to chlorine

I rated this product with 5 stars because I can not judge every 14 days to the silicone seals my shower and my bathtub Try and thus the durability of the joint sealing, despite the use of this "sharp" cleaner for years. Unfortunately, I have this product can no longer buy in the open trade, so I've set up a store on Amazon. When applying Biff mildew remover Although the chlorine smell comes out considerably, but airing after half an hour is simply everything super clean and hygienic.
