I was skeptical, but it works!
Our shower is large annd deep and mold grows on the left corners where the shower head is because air circulation is bad. We have had a mold problem for years due to several showers being taken in there every day, the mold could never dry out. I tried bleach, hydrogen peroxide, every type of toxic mold cleaner and it never went away. But it was nasty! So I tried this stuff. First of all, I followed directions to a t! I placed a fan in my shower to really really dry it out. I took the shower brush and scrubbed the dry mold. Then I cleaned it. I dried the whole shower with a towel and let the fan dry it out fully. Then I put on gloves, a mask (you’ll need it- it smells like chlorine!) and eye protectant (just in case, the gel doesn’t splash but there were times when I was squeezing out the bottle that it “farted” and I was glad I was wearing eye gear). The bottle comes with a nozzle that allows you to target specific areas. There is a cap on the nozzle you have to take off. You also have to open the bottle- it’s a foil cover you peel back. Then you point the nozzle at the mold and gently squeeze for the gel to come out. The only trick is not to “scrape” the gel with the tip while squeezing it out- otherwise it moves to the side of the grout and hollows out where you actually want it to go. It took some trial and error to master just having the tip hover above the grout line and not actually touch it, but when I got it, it was pretty easy!!! Then I went to town following all the horrid grout lines. And there were a lot. I’m talking subway tile. I did not have enough of the gel to do the whole thing, but holy cow! You can see where I didn’t put it!!!! I would tap the bottle upside down to make the gel move to the nozzle to make squeezing easier. I used the entire bottle. After I put the gel on, I let it sit for almost 5 hours. It was amazing. The mold was gone underneath the gel. I took a damp cloth and wiped it and the gel had the consistency of dried candle wax and just fell to the floor. I gathered it up and put it in a trash bag. Then I cleaned my shower and let it dry fully overnight. After the gel dries it still smells like chlorine, but after throwing it away there was no remaining smell. I am impressed!!! You can see the areas that I put the gel so clearly, it looks like new tile. Some tips: 1. dry the shower fully!!!!! If the mold is wet, it won’t work. 2. Don’t let it come in contact with clothes! I had a blob fall on my sweats and I rinsed it with water but it left a little bleached spot. 3. Wear eye gear and disposable gloves. The bottle will fart. 4. When I picked up the dried gel, I just held it in my hand and slipped off my glove inside out, trapping it in my glove and creating a little pocket for it to be easily put in a trash bag. 5. Even the gel can stain! I dropped a dried gel in my rug and it left a tiny bleach mark. 6. Be generous with the gel. The areas I didn’t put a lot or did thin lines had some mold spots that did not fully erase. 7. Let the gel sit for longer than you think. I had black slimy mold and I left it there for almost 5 hours. It’s gone!!!! 8. Trust me. Buy at least 2 bottles. You wont regret it. All in all I am so happy to find this product and am already buying more to finish the grout lines. 100% effective.

Amazingly effective & easy to use
This is an amazing product. I used it on the gasket on my front load washer. Despite monthly cleaning & leaving the door open when not in use, the gasket was moldy & stained, sometimes clothes would get black on them when passing over the gasket. I used the entire bottle of this remover & followed all instructions. After wiping it off, some mildew remained. However, in time, the product continued to work & in the following weeks all the mildew was cleared off. I am so impressed with it that I bought it again & used it on the grout in the bathroom. I am shocked at how well it worked on the grout! I wish I had taken a “before “ picture. This clean area was completely black before using this product.

This stuff is amazing.
This stuff is amazing. I have a walk-in shower with tile floor and tile walls with a bead of caulk where the floor and walls meet. There were a bunch of black mold marks in the caulk (wish I had take before and after pictures, but I really did not think this stuff would work as well as it did). I have tried scrubbing, bleach, oxygen bleach to reduce the black marks. This stuff made the marks go away completely. No harsh smell either. Just squeeze it on, walk away for a while and rinse off. Caulk looks like new.

The gel works well, but the bottle is a pain
Pro: The mold remover itself does a solid job at removing tough mold. I had mold stuck in tub grout that I couldn't remove with other scrubbing and cleaning products. I've tried everything from scrubs, baking soda soaks, bleach, etc. and although all of those helped remove some mold deep in the grout, it was never enough. I read a lot of reviews on this product before purchasing and I will say it definitely does a really good job. It works much better than a spray or scrub as the gel has time to sit and penetrate. I left the gel on longer than recommended as other reviews made a recommendation to leave it on for longer. I left it on for 6.5 hours. The smell is stronger, like a chlorinated hotel pool (which didn't personally bother me) but I'm noting it for those who are sensitive to such smells. Also if you have littles, make sure they get a bath or shower first before using this product. I wiped down very thoroughly, opened a window to air out and sprayed down the shower with our adjustable shower head and waited overnight before using. You really want to make sure the chemical is completely cleared out. As some other viewers commented, it is intense and does leave bleach stain. I hadn't noticed but I had gotten a very minor bleach stain on an old pj top I was wearing while using this product. My main con: the bottle itself is a pain to use and for me to do all of the grout lines of my tub, it took 2.5 bottles which certainly added up. I'm very happy it worked as I was desperate to find something that could really do the job but I had to purchase 3 of these bottles to do my entire shower which was a bummer. Other reviews mention that it can shoot out (which is very true) and it was tricky getting the mechanic of applying the gel on the grout. It seemed like it was easier to apply it vertically down the shower grout, rather than horizontally across the grout. The only time applying was "easy" was along the edge where the tub and shower tile meet. Application was mildly frustrating and I definitely wore gloves and clothes I didn't care about. It recommends wearing eye protection which I did not do but I understand why and would probably recommend the same for future use. It did shoot across the tub a few times when I was squeezing some gel out. I'd also recommend wearing long sleeve as a tiny bit got on my arm and it did tingle a bit. "A little goes a long way" does Not apply here. Other reviews mention this as well indicating that the best results came from areas where heavier use of the gel was applied. I found this also to be true. Because I had to purchase 3 bottles I would say this was a rather pricey job. If you only have a small area of mold to remove then it would be considered a moderate value but if you have a bigger surface to kill then it will definitely cost more as I found one bottle doesn't get very far. In comparison though, I've spent money on various scrubs and cleaners that didn't produce the same results so take that into account

I'll be honest, I went into this with very low expectations. I've tried many other "miracle" cleaners on my stubborn window sill mold before, and most barely made a dent. However, Active Mold Stain Remover completely blew me away. The results are nothing short of spectacular. I applied it to some deep-set stains on my sealant, and it worked incredibly well, far better than I ever expected. It tackled the mold that other products couldn't even touch, leaving everything looking brand new. If you're dealing with tough mold stains and feel like you've tried everything, give this a shot. It actually does what it claims to do. I'm seriously impressed. There was no scrubbing at all. The scent was surprisingly minimal. I applied the product and walked away. I actually left it on overnight, but I didn't need to, the mold was completely gone in a few hours. It tackled the deep, persistent stains that every other product couldn't touch. If you want a set it and forget it solution that actually works, this is it.

I was looking for a product that would remove old black mould and stains from my washing machine seal. My husband was dubious about finding a solution. I tried this remover and was amazed that the mould was completely eradicated. Easy to apply as a thick gel. I left it for 5 hours as recommended and wiped off the now hardened gel to find a lovely clean seal. Since used it on the kitchen window ledge seal with exactly the same result. Highly recommend this product.

I purchased this to clean the door seal of a washing machine we inherited with a house purchase. The door seal had seen better days and was quite discoloured. I was hoping this would kill the visible mould lining the seal and return it to its intended grey colour. Applying the gel was straight forward - though it’s worth noting you do need a Stanley knife (or similar) to cut the nozzle of the bottle. There was no overpowering smell and It was incredibly thick which was great for ensuring it stuck to the surface I was applying it to, but it did mean I ended up using more than I probably needed to had it spread a little more. That said, there’s plenty for two applications in one bottle since it’s a good size. I left the gel to work for three hours. It worked well, removing the black mould and only leaving a slight discolouration in its place. I imagine it would be completely cleared after a second application (or perhaps if I’d allowed it to work a little longer). Clean up was relatively straight forward, but you will need plenty of damp and cloths to get it removed fully. Overall, I’d say it’s good value for money.

This stuff works like crazy. The caulking in our bathroom was done poorly and there was mold. Leaving this stuff lifted mold that has been there forever. I should have taken photos but it was gross and a lot of black mold. Would recommend 💯

I saw this on social media then looked it up on Amazon. After seeing all the raving reviews and the before and after pics, I decided to give the Mold Stain Remover Gel a shot. It really works, people! I had some stain around my tub. This thing got rid off them without me even doing much other cover the stains with the gel then going to bed for the night, and then wiping the areas with a damp rug the next morning and washing the areas. One problem with the product I had - and that's why I'm giving the review 4 stars instead of 5: the pointed cap I received in the box which was supposed to make spreading the gel easy and efficient had no holes. I tried to puncture the top to make a hole, but just couldn’t even with a knife. So I had to resort to squeezing the gel on a butter knife and spread it over the mold stains to cover them. Which was...an interesting experience I didn’t think I'd have. BUT the stuff really works and it doesn’t require any elbow grease at all. Which means, it's very, very strong. And it's VERY strong chemical-wise. So definitely use gloves and protect your eyes. Your space will smell of a bleach/chlorine-like strong smell. It doesn’t last a day or anything, but the smell is strong. So, that's two things to keep in mind. Will I use the product again? I hope no mold returns but if that ever happens, YES 100% I'll use this. I'll also recommend the Mold Stain Remover Gel Cleaner to everyone else! Also, they're a small, family-run business and I really love that for them. The handwritten thank-you card was a really nice touch. I saved it. I actually save the thank-you cards or notes I receive from real people I buy things from. It feels nice!
