Worked great on musty wood vintage desk
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 used cotton rags, cut up from t-shirts,instead of paper towels. 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 enough into 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.

Small mold issues
As a real estate professional, I’ve encountered many small surface mold issues during pre-listing prep and inspections, and Concrobium Mold Control is my go-to product for minor projects. It’s easy to use, has no harsh bleach odor, and works well for treating small affected areas like bathrooms, window sills, and closets. For homeowners, it’s also helpful to know that the EPA generally allows individuals to address mold themselves when the affected area is small (commonly referenced as under about 10 square feet) rather than requiring professional remediation. For those limited situations, this product has been a reliable solution in my experience. Of course, for larger infestations or hidden moisture problems, I always recommend professional mold remediation. But for small, visible spots, this has consistently been an effective first step.

Works like magic, and no VOCs or dangerous chemicals
This stuff is a godsend for me. I live in an older home near the ocean, so it's damp here, and I perennially have to deal with mold. I hate scented products, which can make me as sick as the mold itself, so to be able to remove the mold with zero VOCs or added scents -- perfect. Yesterday I removed ugly black mold from the grout around my windows. Spray it on, let it dry, come back with a narrow stiff brush moistened by Concrobrium, and the mold gives up the ghost. It's like magic. And then it continues to project the surface even after you've wiped it off. I'm really very grateful for Concrobrium.

Gets Rid of Mold
Works really well on mold. Doesn’t have a lingering smell. Was able to wipe off the mold and did not have to leave it sitting very long. We had mold over our door way from condensation in the Summer. It took it and the discoloration right off of the painted sheet rock.

Works well on light mold
It’s an okay product. It does help with light mold, but I didn’t see a huge difference on tougher spots. Easy to spray and doesn’t have a strong smell, which I liked. It works best for maintenance or small areas, but not a miracle fix.

This stuff works, is fast and odor free.
Not totally fond of the spray bottle, it sometimes seems to leak some on your hand when triggering. What is inside the bottle though seems to work very well. If the mold is at the point where it looks furry, hitting it with this stuff knocks it back to a slime that seems to be easily removed. I had this white mold in my attic, on some rafters, and it seemed to do the job well. Rafters that I was able to leave in place, I hit 3 times with this stuff, although twice would likely be enough. From the standpoint of saving your structure, this chemical is very inexpensive. You can also buy it in a gallon jug, much more economical and provide your own spray bottle. I purchased both as I had a large area to cover. I stripped the decking off my roof in the infected region, so I was in the open air, but near as I can tell, there is no odor coming from this chemical. Of my 5 quarts, I have about 2.5 left, but would definitely buy again.

Under the sink base there was a mold on the wood. Applied this spray 3 days. Seems like it handled situation well. But if your wood is too damaged or the mold is deep you will need a prof cleaning. Spray wont help.
