Having used other mold shower cleaners and a lot of scrubbing , a single application of this and the shower mold melts away. Open all the area windows, ventilate well, your hair and body will smell like this cleaning agent, and wear a respirator. This is super potent but got the job done . A transferred some to a spray bottle . Wear goggles for eye and splash protection. I used this on shower ceramic towels and grout cracks where black mold infiltrated . I usually need something like this twice a year for the walk in shower.
