siamons international 25326 Mold Control Spray, 32 Ounce (Pack of 1)

Only took a few minutes to get black of walls so far great

For the price I could have bought 40 bottles of bleach, this item was so expensive and claimed to do the job what a load of malarci won't be buying this again for sure

After a flooding inside the house we had a problem of repeated mold growth. Spraying this regularly solved the problem.

I had a musty smell coming from a closet that had had a leak. I wanted to kill the mold on the floor and walls but I didn't want to kill myself in the process with a toxic product. Even chlorine bleach is toxic in the environment, despite its being commonly found in most homes.Based on other reviews, I decided to try this and I am very happy that I did. The closet it now clear of the musty smell and I used it in the shower stall next. Mind you, this will not give the immediate gratification that bleach would. It does NOT bleach out the mold stain and it does not claim to. It is killing the spores, which is the most important part. Remove the stain using another method, which may involve a 10% bleach solution in water. (I know. The frustration of it all.) Check other sources, such as Pinterest, for ideas. Do not be disappointed that this product does not do it. This allows it to be used on surfaces that would be harmed by bleach, such as, fabrics, furniture, carpeting, car interiors. In fact, I ordered some for my sister who has a car that got wet inside and now is musty. I am confident that this product, along with copious amounts of fresh air, will solve the problem.Everyone has mold somewhere in their environment. Try this. You will, no doubt, be happy you did. I am. Can you make it cheaper, as suggested by another reviewer? It is not worth it for me to try that. This is cheap enough.Mold is a challenging environmental problem that has a huge impact on human health - more than people realize. I am just happy that there is a product like Concrobium that allows me to control it in a non-toxic way.

The stuff isn't magic but it does it's job if you follow the instructions and use common sense.I cleaned my apartment window first and then sprayed this stuff on the mold spots. It killed the mold and then I cleaned the window again and sprayed a little bit of this stuff again. I haven't seen mold come back since.I also used this to kill mold inside of a car that had water leak inside it and it worked. I sprayed the mold in the car and waited a minute then wiped it off and sprayed again to prevent future mold. I haven't seen any mold come back yet.

Coming from the nutritional supplement world, I've learned to trust the ingredient label (in this case MSDS sheet) more than the marketing. When I received this product I found odd that it stated "Sodium Carbonate: 0.95%, Other ingredients 99.05%" on the front of the bottle. With the 99.05% accounting almost in its totality for the water, that leaves very little active ingredient. And to make matters worse, Sodium Carbonate is just 'Washing Soda', a cheap household chemical. I didn't really get where the special "mold crushing" ingredient was.After I checked the MSDS (Material Safety Data Sheet) for more info, it only listed "Sodium Carbonate: <1%, Trisodium Phosphate (TSP): 1-5% (by weight)". Both are cheap household chemicals a large section of people already have. Washing soda is used for laundry, and TSP is a general purpose household detergent and degreaser. If that's all this product is composed of, it isn't special at all. With a box of each (under 20$), you could make hundreds of gallons of the same liquid. I even poured Concrobium Mold Control liquid out of the bottle and it's pretty much crystal clear and odorless, so it certainly isn't evident that it's saturated with some special mold-annihilating substance.In the end I decided to just make my own using a 16oz empty spray bottle, around 500 grams of distilled water, some 5 grams of baking soda, and some 20 grams of TSP. The resulting liquid looks pretty much identical. Out of curiosity (and because I had the tool at hand), I checked the specific gravity of each liquid with a refractometer. Both the 'Concrobium Mold Control' and the DIY mix had very similar specific gravity, and barely above that of distilled water. In other words you're pretty much buying water with this product.Personally, I think I won't ever buy this product again and I'll just use more heavy duty chemicals if the issue is needed or just mix my own for light cleaning.
