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.

Does what it says...kills mold
This stuff worked quite well. We had some nasty looking mold going on in tub and I put this on it and it has taken care of 95% of the mold. I am going to do 1 more treatment and that should take care of it. I noticed that if you just leave it on there for a couple days makes it work better and its easier to come off. The application was easy (give it a good shake first). Wiped up pretty clean, no residue. Its a bit strong on the chlorine smell but that's to be expected. Definitely worth the price

Have you tried it yet? If not, I suggest you give it a shot!
I recently tried the ACTIVE Mold Stain Remover Gel, and I must say, it exceeded my expectations! Here’s a detailed breakdown of my experience: **Effectiveness** From the moment I applied the gel, I noticed how quickly it began to work. It penetrated deep into the mold stains, effectively lifting them from surfaces. I used it on various materials, including tiles and grout, and each application resulted in a noticeable difference. The stubborn black spots that had been there for months disappeared with minimal scrubbing. **Ease of Use** The gel consistency is fantastic. It clings well to vertical surfaces, preventing drips and allowing for precise application. The nozzle design made it easy to target specific areas without wasting product. I appreciated that it didn’t require complicated mixing or preparation—just apply, wait, and rinse. **Safety and Odor** One of my concerns with mold removers is the harsh chemicals often involved. Fortunately, ACTIVE Mold Stain Remover Gel has a relatively mild scent compared to other products I've used, making it much more pleasant to work with. Despite being effective, I felt safe using it indoors. **Value for Money** Given its performance and effectiveness, I found the price to be quite reasonable. A little goes a long way, and considering the time and effort it saved me in cleaning, it’s worth every penny. **Overall Impression** I highly recommend ACTIVE Mold Stain Remover Gel to anyone dealing with mold issues, whether in bathrooms, kitchens, or outdoor spaces. It’s a reliable solution that delivers results without the hassle of strong odors or complicated application processes. I will definitely keep this product in my cleaning arsenal moving forward!

Works Well, Just Needs a Few Applications for Tough Stains
I purchased this mold stain gel remover to clean some stubborn stains in my washing machine, and overall, it worked well. It definitely does the job, especially on lighter stains, and I could see a noticeable improvement after using it. For the tougher, more set in mold stains, it did take a few applications to fully remove them. I do wish the instructions made that a bit clearer upfront, since you may need to use it multiple times for the best results. One thing I really liked was how secure the bottle is, it feels well designed and easy to handle. The smell is pretty strong, but wearing a mask helped make it much more manageable. Overall, I would still recommend this product. It works and does remove mold stains, just be prepared to put in a couple rounds for the more stubborn spots.

Great product, just a little hard to apply for an older person
Using it right now for the first time. So far it’s working great and within about a half an hour I could see the mold going away. One thing I noticed while trying to put the gel on my caulking area in my bathtub, is that the plastic is pretty hard on the bottle and for an older woman without a lot of strength in her hands, I had a very hard time squeezing it out and getting a steady stream. So, what I would say is the application is hard for someone without a lot of strength in their hands. It’s a great product, but it was a workout to try and get that on there for me. My hand aches from trying to get the gel out. My advice would be to try and have someone younger do this for you lol. It’s been a few days since I used this product for the first time and I have to share another benefit with you. Before I used this, the mold was getting pretty bad on my caulking, and it not only was on top of it, but it was underneath as well to the point where the caulking wasn’t sealing the tub area anymore, and it had become brittle and wavy. This product removed all the mold underneath the caulking that I couldn’t see, and in doing so, it has completely revitalized the caulking around my tub. It’s flat now and it is sealing the bathtub again. It’s like the caulking has memory and it’s laying flat now and it honest to God looks like I just re-caulked the entire bathtub. It has completely refreshed my caulking as well. It looks brand new after several years.This product is magic!

Thought it was too good to be true...
I don't write many reviews but felt compelled this time to share my experience, as rarely has a product exceeded my expectations like this. The rubber seal of my front load washer was completely black an sooo disgusting. Nothing worked to clean it to the point where I was considering a costly replacement as it was just that gross. I had seen this product advertised before but hesitated to buy it as there seemed to be a lot of disappointing reviews. I was so convinced it wouldn't work I didn't take a before picture. Imagine my shock and outright delight when this product completely cleaned the black mold stains like they never happened! As an added bonus, the bottle is larger than expected, enough for multiple applications to keep the good clean vibes flowing. I made sure I followed the directions EXACTLY, which included making sure the surface was scuffed and completely dry before applying and it only took one application. As a safeguard against any residue, I ran a clean cycle afterwards and my washer now looks brand new inside. I'm so pleased I plan on trying other products from this company... they are on to something!

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

Best product line I have found!
I love this stuff so much! I was skeptical that it could clear the mold we had in the shower, but it knocked it right out! I was so impressed that I decided to try another one of their products, I think it was the Garbage Disposal cleaner, and again, super impressed! I have gone on to purchase multiple products from the brand: stain remover, enzyme laundry booster (amazing!), pet laundry soap (SUPER AMAZING), the heavy duty laundry soap (also amazing), coffee maker cleaner pods, dishwasher cleaner, and the washing machine cleaner ( regular and the one for pet owners). Heck there might be more but I have never been disappointed by any of their products. Plan to keep trying them as I find need for them. Highly recommend them to anyone. I love that products are made in USA. The pet laundry soap and enzyme booster have got to be my favorite with this mold remover as a super close second. No more lingering smells after washing my pet’s bedding! Give them a try, you won’t regret it!

The only thing that actually removed the mold from my window sill
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.

Best mould remover
I never usually leave reviews but this product worked so well I just had to. My window was so mouldy living in rented accommodation and nothing would get rid of it but I used this and it worked within hours. Couldn’t recommend this more. It was easy to remove with a sponge and the smell wasn’t offensive. It was easy to apply and is a good sized bottle so worth the price.

Actually Surprised
Fully expected a cheap failure product advertised everywhere. Bought out of desperation. It works. It actually works.

Works brilliantly at removing black mould on washing machine seal.
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.

It REALLY works!
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!
