Promising review: "This stuff is amazing. I have a stall shower that was always moldy, mildewy, and just plain ugly. I could never find a cleaner that would actually get it back to white and sparkling. This did it! I sprayed it on and let it work, rinsed it off (to get the smell to dissipate), and it was gone. My shower is the 3"x3" small squares; the grout lines were ugly and made me want to remove the whole thing and start again. Not anymore. I just saved myself hundreds by using this product! If you're frustrated by mold...give it a try. It is extremely strong so make sure to have ventilation and maybe even a mask if you're going to be using it. Once it's rinsed it just leaves a clean, bleach smell. If you're able to be away for a few, it doesn't even need rinsed." —Mnypnny281
