It killed black mold growing in our shower. It wasn’t instant. I sprayed twice in the daytime per the instructions and then would scrub it with a washcloth after showering. It completely removed the mold.
This stuff is amazing. We had some staining that we scrubbed and tried several other products on. This stuff was as easy as spraying it, letting it sit for a few minutes, and washing it off.
My restroom walls were full of stains and mold stains. Very easy to use, and definitely works my walls and restroom look so white I was amazed. It does have a very strong bleach smell. I would recommend wearing a mask and having windows and doors open.
We had a continuous mold problem in our basement. I can't count the hours I've spent scrubbing. Finally, I want to hunt for something new and read the reviews for this. IT'S ALL TRUE. You simply spray it on and walk away and the mold is gone.
I did not think this would work. I scrubbed and scrubbed before and could not get the mold and stains out of the sink and tub. But spraying within seconds the mold and stains just melted off. Amazing! The smell is a bit strong. But this stuff works!
