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.

Used this product in the bathroom to kill some pink mold. It seems to work really well. When it dries, it crushes the mold and I can see the mold exploded after it dries. I just wipe it with a damp cloth after and then spray again for a protective barrier. It's been months and the mold has not returned.

Product itself works well, just spray and leave it on without washing away. However you need to use a lot, and the spray itself is not that much product. I essentially had to dump it on my bathroom tiles, but when I returned it was as white as snow! Will purchase again, but maybe change the way I distribute it.

This stuff is awesome! We live near the Ocean and have a lot of issues with mold, especially in the closet areas. I've scrubbed my walls down to get rid of the mold then saturate the walls with this solution and keep the fans on till the wall dries. I usually treat my closets after every season is over. It really is mold resistant.

I had a leak happen in my basement that I didn't catch in time, and even after water extraction, this product came in clutch. Will buy again

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.

great product great price

It says let dry, no scrubbing or rinsing required. I let product sit for an hour and nothing. I wiped it off with wet rag and have to scrub and use a toothbrush to get into cracks.
