Review: Magic spray - This product is magical. I tell you my DIY friends about how it effortlessly cleans stubborn mold stains. Use this product on outdoor pvc railing to make it perfectly clean without any scrubbing. It works on composite decking. I've tried powerwashing the railing and deck with no results, this spray makes all the difference. I've also use this product in my tiled shower as it removes all signs of soup scum, no scrubbing required. If you have any pool swimmies or plastic toys left in a damp environment with mold spots they will disappear but the bleach may also change their color. The fumes after spray are very strong. I recommend wearing a mask even when applying outside. It's not worth injuring your throat, lungs. I've heard others wear gloves. I only wear gloves for bigger jobs. Bottom line. Add this to your set of tools. Every house should have a bottle.
Review: Eliminates mold and stops it from coming back! - This is an outstanding product!!! I had received a FB ad for a similar type mold removal product. I found this brand on desertcart and decided to go with the pro version. We have a tile and glass shower and have been dealing with black slimy stuff in the corners for the last few years. Even after cleaning, it never looked that great. I mixed this up, sprayed it in the bottle and it virtually all went away but for one corner I'm going to retreat. What's better is it has stopped the mold from coming back. I also had some green mildew on our front porch that I treated with this and it went away as well.

### ⭐⭐⭐⭐⭐ Best mold removal product on market!
*by B***Y on December 6, 2025*

This product is nothing short of a miracle. Bought some 60’s vintage wicker furniture and the original cushions had black mold spots on a very delicate fabric, otherwise in great shape. Really wanted to keep the pieces original we tried all the standard cleaning remedies for mold, borax, baking soda & vinegar, etc.. I was ready to give up ehen I found this product on Amazon. The effectiveness was evident immediately. You know you have the right stuff when the dirt starts to disappear almost instantly. No harsh smell and completely removed the mold and other stains. Bought this size after using smaller bottle as we know we’re going to use this on everything. Don’t waste time and money on anything else as this is far and away the most effective spray product on the market!
