Have (not the whole set) bought the mold remover to treat the silicone joints in the shower. There are some black mildew stains were present for a long time, the surface no longer could take off. Had penetrated deeply. Already after the first treatment distinct brightening, after a 2nd treatment further improved. Black spots are no longer visible, now only yellowing. In places that were only slightly discolored, it is completely lightened. I'm very satisfied with the result, because the stains had long since, and therefore could not completely disappear immediately. Eventually I make again another application, then it will certainly be better again.
A star deduction, because it really badly stinks of chlorine (but disappeared with good ventilation and washing with cold water after exposure to fast again) and since have etched their hair in two brushes used! Oh yes, when applying I wore gloves and the worst joints with kitchen roll and the middle "glued" to increase the success. All in all, I would buy again ... and new brush to ;-)
