Concrobium29665 Mold Stain Eraser, 22.9 oz.

I used this in conjunction with Concrobium Mold Control to treat mold and fungus growth in a crawl space. I found it to be effective and easy to use.When we bought out 50 year old house, the inspector mentioned that there was fungus growing on the wood in the crawl space. I put it on the list of things to do. A termite inspector noted it also and gave me an outrageous quote to take care of it. My desire to stay outside of bankruptcy won out over my claustrophobia so I set out to research if I could do a DIY job. I researched a lot of products and chose this system because it's easy to use and provides protection for the future.I didn't know how to identify fungus or mold so I just treated everything. It took about a month of weekends and a few days off in between. I got about 90% of the way done and decided to take a break. That was last fall. This spring I went down there to turn on the outside water, and I noticed that the treated area looks like new. The untreated area now I can tell what the fungus is supposed to look like. It's all over the untreated wood. So this weekend or next I'll be doing the last section. I hope there are no spiders in there.

Concrobium Mold Stain Eraser does more than mold stains. It's FANTASTIC!!!!! Best I've ever used. Can take some time but not that long. Can repeat application. Only damaged one shirt slightly when I put the powder on directly and brushed (Not following directions) Most of my stains are organic. But did remove some dirt/oil stains it removed.It even removed a rust and nasty chemical stain on Formica count top. Bleach and vinegar help a little but changed the color of the stain. Mother's rust stain remover helped as well but still there. Saturated paper towels with Concrobium and the stain was gone. Well a faint bit left. So I put bleach and vinegar on it again and the stain came back slightly. So I reapplied Concrobium and the stain disappeared again. Strange. Almost like it makes the stain invisible.Concrobium has removed stains that have been in clothes and towels for years.Oh. And it does remove mold stains in carpet and clothes as well.On the down side it does put off some nasty smelling fumes if you mix it in really hot water. So don't mix it in an enclosed space. It doesn't seem to bother me getting a little on my hands.

I used this product after applying the Concrobium mold killer (spray bottle) to a small, 8 square foot, black mold area in an unfinished attic area between roof joists. I wasn't happy with how it looked after scrubbing the sprayed area so I bought this product. It got most of the stain out. I decided to repeat the process and sprayed again, scrubbed and followed with the eraser. It looked really good after that. Then I fixed the venting problem that caused the mold in the first place.

Had a pop-up vinyl awning that got rolled up wet and grew black and orange mold. Looked at a few products but chose this because of the reviews. Not the easiest stuff to prepare and use but holy cow did it work wonders. Made the solution and actually didn’t get it fully dissolved... but applied it anyway. Rolled the awning up and left it sit for 15 minutes. Unrolled it and it looked practically new. Some mold spots were still at the very bottom, probably because it did not get fully wet there. But man did this stuff work great. It does appear to make a high pH solution so wear gloves or be prepared to wash your hands if you get it on you. Wish I had taken before and after photos but actually didn't expect it to work so well.

Couldn't tell much difference in deck appearance after used. Acts like it is working and foams like it is doing something... but, not much effect. Sorry, I hoped this would work well. I tried a little on my fiberglass shower floor and little change there either. I will not be buying more.

I used this for the mold in the ring of my front loader washer and it did get rid of the mold! I had disgusting mold and copper stains on the inner ring. If you have a front loader you have probably heard of this problem. Anyway, I used the Concrobium Mold Stain Eraser and let it sit on the ring for hours and it did get rid of the 80% mold, but not the copper stains. I wish I took a before photo, but you can see the after photo. The problem I had was getting rid of the stains that the pool of Concrobium didn't want to sit like the front of the inner ring where the water dripped off. I tried to wet a towel with the Concrobium and sit it on top of the mold on the right and left side of the ring, but that didn't work, so I think to get rid of all the mold stains I would physically need to unscrew the plate of my washer and take out off the ring and soak it in a bucket of Concrobium.Update: If I could give Concrobium 10 stars for cleaning my jetted tubs I would! I had mold on my jetted tubs that I have tried and tried to get rid of. I have used other expensive mold cleaners that didn't work. I just filled the tub with hot water poured the rest of my Concrobium bottle in and left it for 24 hours. I did run the jets a few time to get rid of anything inside the tubes. Anyway, I didn't even have to scrub anything. Everything was gone in a day! You can see in the photos. What a difference this stuff did on my tub, like night and day!I also love that there is really no smell with this stuff! I hate when you are overpowered by the bleach smell.Thank you, Concrobium! I will definitely buying more bottles of this magical stuff!
