Concrobium 25326CAL Mold Control Spray, 32 oz

I used this Concrobium to kill the mildew smell inside a circa 1960s drop front type desk with cubbies and drawers inside. I did it in two stages. In the first stage, I applied it with a paintbrush to all the bare wood and wiped off the excess to clean it, and much grime did come off. I removed and treated the drawers first, two large ones, and five small ones from the inside. After doing the first stage cleaning, I let them dry and then followed with a second coating to treat the cleaned wood. I was generous with the product, but was sure to wipe off the excess so as not to over soak the wood(which I probably did anyway), and so there would be no powdery residue left from the product.I approached the desk cabinet itself in the same way. One coat and wipe down to clean, let it dry, and then a second coat and wipe down to kill the mildew smell. I brushed it on all the bare wood surfaces, including the back and underneath of the desk, inside the large drawer openings, and inside each cubby, and each cubby drawer opening, then wiped off the excess. I left everything to dry for a couple of days, even though it didn't need that long, because the product stated that it actually kills the mold during drying process.The wood was very dry afterward and needed moisturizing/conditioning. I brushed on a generous layer(and wiped off the excess) of "Howard's Feed-N-Wax" wood conditioner which I bought at Ace Hardware. I let it sit a couple of days, then wiped it off any further remaining excess. Fyi, I used way too much I because I had to wipe it down several times with days in between before all the excess came to the surface wiped and the wood has some over saturated spots of conditioner...so I dodged a bullet of comprising the wood integrity by over conditioning...The results were so rewarding. There is virtually no mildew smell left within the desk at all. I am using the desk as well, so it is not being left closed up. The desk had been stored in a garage for 18 years. It didn't have visible mildew but smelled horribly. I believe the product was successful because instead of spraying it on, I used a brush to apply it which gave better coverage, and deeper absorption. Also I brushed it on twice. First time to clean it, and second time to treat it. And because I was sure to wipe the wood down both times afterwards which removed a lot of grime on to the rags. Wiping down will also assure there will be no white residue remaining as the manufacturer warned in their instructions.In my opinion, simply spraying on the product would not have been enough coverage to get deep into enough the wood and kill the mildew for this particular desk. The wood felt very dry after I treated it but the desk already needed conditioning. I probably used more of both products than was ideal, particularly the conditioner because I haven't worked with furniture before.I am so glad to have found this product that is safe to use, has no chemical smell and can be used on wood. I was very fond of the desk as my mom used it regularly when I was growing up and I wanted to keep it after she passed. Before trying it myself, I actually hired a refinisher to clean it but he couldn't remove the smell. He said he didn't know of any product for removing mildew on furniture. This product is also used for commercial cleanup, for example, for killing mildew after a flooding event. Wood, carpet, fabric, etc.

Excellent product. Was able to use the one container to treat wet carpeting damaged during hurricane. Carpet restored without odor and all is well.

Like other reviews have said the sprayer was defective and started leaking right after first use. I was able to switch sprayers and it worked perfectly after that. The actual product is great and got rid of mold issues and is seemingly helping prevent it from coming back.

It is shocking how well this product attacks and removes mold and mildew!

Worked quickly. I usually would have used a mixture of bleach and water to kill mold. But I learned when this mixture hits mold, on a microscopic level, the mold spores Explode into the air. Since there was some thought of this going to be black mold and this product is DEQ approved I got it. This size was a real find!

Does not do what it says on the bottle, and that is eliminating musty odors. It may help with actively growing mildew but I’m not sure I had that. I needed this for removing odors and it did NOTHING for that.

This mold control is great, we had some mold under our rv mattress. Cleaned it up and sprayed this down to prevent anymore growth along with other preventative measures. Highly recommend.

Didn’t work at all. Sprayed it on mold and mildew and nothing. Repeated 3 more times fully letting it dry each time.
