I have long struggle against this black and orange on progressive settled along the tub and tile, as well as traps and drain holes. A friend told me about this product that are not found at DIY radius of some stores, and unfortunately not in department stores or with conventional cleaners. Indeed it would have no place alongside the traditional cleaners as this one is truly the most powerful. As soon as I received my first bottle, I literally revived my bathroom and my next were white like the first day of their installation. Actually the smell is pretty strong, so when I let it sit, I avoid be, but effective! This helps get rid of definitive way that all colors and molds who love too much water our bathrooms. Frankly after eradicating what was really visible and the mark on the seals which bothered me, I attacked all the rest, including the attack along the white tiles and large, this product gives life and health to all the bathroom, including black sticky as can be seen below the grids evacuations sinks, baths but also sink, I spray it to the inside and a few hours after rinsing, while both shines again.
Frankly I would like this to be available to the household department stores. I order several days while a beating, because it really is really effective and I really recommend against these pesky black mold seals, also put those red-orange and appears embedded in the joints. Revolutionary!
