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 (youâll need it- it smells like chlorine!) and eye protectant (just in case, the gel doesnât splash but there were times when I was squeezing out the bottle that it âfartedâ 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- itâs 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 âscrapeâ 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. Iâm talking subway tile. I did not have enough of the gel to do the whole thing, but holy cow! You can see where I didnât 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 wonât work.2. Donât 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 didnât 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. Itâs 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.

Great Product! Highly Recommend.
This worked super well!!!! Left side is before, right is after.TOP ROW: I have been trying EVERYTHING to get rid of this stubborn mold behind my kitchen sink and nothing has worked. I have scrubbed it tirelessly with bleach and a toothbrush, scrubbing bubbles, overnight bleach + TP combo. NOTHING! I left this on for about 5 hours and it got a majority of it off with a single wipe of my sponge! Iâm going to do a second round to see if it can get that last bit off.BOTTOM ROW: I also tried it on my shower grout because that just gets like that regularly and Iâm usually able to get it off easily with scrubbing bubbles and a sponge but this was A) was easier and less work B) totally deeper clean C) didnât make my bathroom full of crazy fumes.I will 100% be using this again and purchasing again and I will recommend to my friends. I also love that they are a family owned small business!!!

Works like a dream!
Works incredibly well! I was so shocked that it actually worked on the caulking in my shower. It comes out as a gel and hardens onto the stains. Wipes away super easily. Doesnât stink up the bathroom with strong fumes but it will make your hands smell like bleach, so make sure to use gloves like they suggest. Totally fixed our mildew problem. I was going to take a knife to our caulking and probably do damage. Iâm so satisfied with the results and would recommend to anyone. Good news also that the fix used up maybe 1/10 of the bottle? So now Iâm doing more areas that donât look great. Shower will be looking brand new in no time. Super great payoff for not a very expensive product.

Absolutely works!
This is my second time buying this! I could not believe this worked. I first bought this for my shower and washing machine (didnât get before and after pictures unfortunately) and it completely removed the mold. I was shocked so I started using it on every place I found mold. Now if the mold was super bad (I.e. the pictures I attached of my kitchen sink) youâll have to apply this twice. But usually that does the trick. Smell isnât bad, it does smell a bit like bleach but itâs not overwhelming.One tip: make sure the layer you apply isnât too thick. It still works but it wonât dry all the way. A good thin layer is the best results that I have found.

BEST PRODUCT FOR MOLD STAIN REMOVAL!!!!!
I bought this product after trying nearly every cleaning product to get rid of what I could only assume was recurrent mold in the caulking of my shower. I did NOT want to get maintenance involved at my apartment complex if I could help it – so I went out on a limb and ordered this product for one final attempt of solving this issue. When I tell you this product worked so well I could’ve jumped up and down in excitement. It did a PHENOMENAL job removing what I now realize was mold staining, not active mold. I would recommend this product time and time again.

My Washing Machine Seal Is Clean!
This product worked quite well on my washing machine seal to remove mold stains. There was enough product to do the entire seal of one front loading washing machine. It was easy to use. Make sure you wear gloves and have an old toothbrush handy to spread it around into the small grooves. It will ruin your clothes if you spill it so take care to protect your clothing. Expensive product for the small amount, but it does what it is supposed to do.

It works
The tip provided does not work for grout along sink, way too large and the material is not flexible, hard plastic. The substance is quite thick so it would not go through the tip anyway. You will need a scoop like tool to get it out of the tube like container it comes in, apply directly to the mold, and it really does work. It is the only substance that has worked for I have tried everything. It smells like a strong bleach. It works, but no easy use!

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.

Best product ever to remove the mold and smell. I tried everything to get rid of the mold and smell when we bought our house that came with appliances. This is the only product that worked. Easy to use. Just spread the gel, wait a few hours and then wipe (i left it overnight). Every came off and machine is just like new

I was really impressed with how well this mold remover worked. It completely lifted the black mold stains on my grout and tile, leaving the surface looking fresh and clean. The formula applies thinly, which makes it especially effective for getting into tight spaces between tiles or around seals. For smaller problem areas, the precision tip makes application quick and easy.That said, because the consistency is thinner, covering large surfaces might take more time and multiple applications to get even coverage. Still, for grout lines, caulking, and smaller sections, this product does exactly what it promises. A great option if youâre looking for a reliable, targeted mold stain remover.

Genuinely amazing product. I had some really gross black mould under the seal and in the grout on my bath and I was resigning myself to not getting the deposit back. Applied the gel, went to work, and when I came back the black mold was gone and the caulking looked magnitudes better. No scrubbing required!

Fairly good mould and mildew remover but not as brilliant as some of the claims, especially with old ingrained mould, but still good.
