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.

If you’re dealing with stubborn mold or mildew, don’t hesitate—this stuff works. See pictures for proof! Highly recommend ⭐⭐⭐⭐⭐

Easy, Economical, and Effective
The caulk lining in our shower seemed to always end up with mold growing on it. I've tried before to clean it manually with some abrasive, but it often just leaves more grooves for mold to grow in. I've also tried some other cleaning solutions but they left a super strong odor due to them being spray. So, my previous solution to this whole mess was to rip up the caulk every 6-12 months and replace it - which is a pain in the butt! I found this product through an ad on Instagram and thought I would try it. Well, it worked out great! It is easy enough to just shake and lay it down on the affected area. Forget about it for a while, then come back and wipe it off. The mold went right with it, saving me from a few hours of painful cleaning. There was a slight smell to this since it does contain some amount of cleaning solution, but the form factor of gel really reduces it. Not to mention that it was under $15 when I bought it and it seems like I have a few uses worth in the bottle. It seems to be worth the price.

Effective on Tough Mold Stains, but Use with Care
This mold stain remover gel works well on stubborn mold and mildew, especially on grout, caulking, and other hard-to-clean areas. The gel consistency is a big advantage because it clings to vertical surfaces instead of running off, allowing it to sit and work as directed. After letting it dwell, I noticed a visible improvement with much less scrubbing compared to regular spray cleaners. It’s particularly effective in bathrooms and damp areas where mold tends to build up. The results aren’t always instant for very heavy staining, but with a second application, it significantly lightens or removes most problem spots. That said, the product has a strong chemical smell, so good ventilation and gloves are a must during use. It also requires some patience, as you need to let it sit long enough to see the best results. Overall, this is a solid and effective mold stain remover that delivers on performance, with minor drawbacks related to odor and handling precautions.

This stuff if GREAT!
Don’t hesitate to buy this product if you have mold/mildew problems. I have to admit I was skeptical about this product. My shower has a very small area of clear silicone caulk that I have to remove due to mildew about every six months or so. I tried this product on it and it WORKS! It did require a second application, but WOW! It also removed mildew/mold from the grout. I’m amazed and will keep a bottle of this from now on. No odors noted. I did use gloves when using it. The nozzle is helpful to apply.

I almost gave up on the mold stains in the shower grouting. The black mold stains wouldn't go away even with constant brushing. Good thing i tried this product. After several applications, the grout looks new again. All you need is patience.

I used it for my washing machine silicone door seal which was full of mould stain. It worked like a magic. Left it over night and all the stains are now gone. Very easy to use. Great product.

Worked amazingly and took off all the black mold in the rubber seal around the old washing machine. The instructions were straightforward and easy to understand. I did two rounds on some harder areas but most only required one, so amazing value for money. It did smell of bleach but not any more than expected, and this was easily dispersed with a cracked window and by washing the area after. The only thing I'd note is that squeezing the bottle to get product out after the first half was gone was really difficult and I don't know that anyone without a significant amount of grip strength would have had an easier time. I ended up squishing the product out onto a plate and then using gloves fingers to wipe it on after a point. To be clear: there was loads of product but if you're squeezing for something where the bottle as to face up (as I did getting the top inside of the rubber seal), your hand will be aching for hours.

This product is amazing! I used it to clean the rubber seal on my washer. I was skeptical, after all, this is mold I’m trying to remove. I followed the directions and the results were unbelievable! The mold was gone! My only regret is I didn’t take a before picture.

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.
