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.

This mold stain remover is like magic. I had stubborn mold stains that I thought would never come off, but they disappeared with very little effort after using this product. It offers great value for money because a small amount goes a long way, making it well worth the price. The squeeze bottle makes application easy and lets you apply the product exactly where it's needed without making a mess. It didn't leave behind any residue just a clean, fresh-looking surface. I also liked that it was gentle on the surface and didn't cause any damage or discoloration. The scent was mild and not overpowering, especially compared to other mold removers I've tried. I would definitely purchase it again and highly recommend it for tackling stubborn mold stains.

This mold removal gel works. The before and after is insane. We have heard water and the mold/mildew turns the grout pinky orange, no matter how much the shower is cleaned. The thick gel is applied on the grout lines and caulking. Application is tedious and time consuming, but worth it for the result. My shower uses 4 boxes, either because I'm heavy handed in application, or there is just a lot of grout. Recommended drying time is at least three hours (if you're area is well ventilated). I left for most of the day and some areas were still not dry due to uneven application, but the grout was clean, so I removed it with gloves scraping the gel into a bag for disposal. The gel has a strong bleach-like smell, and it does linger for a few days. I have used this product several times, about once every 10 months, and it is consistent. Works every time. Picture is of treated and untreated area for comparison.

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

This stuff WORKS. I’m dumb for not taking a before and after photo but trust that I’m giving you my word. I hate mold. I’m terrified of it. It took two coats in some areas of our shower but it got rid of the pink mold all over our tiles and the growing black mold stains. The smell is not horrible. And my shower is clean!!!

I really wish I had taken "before" pictures, but frankly, I was embarrassed about how moldy the rubber gasket in our frontload washer was and didn't relish the idea of posting it. I may have used more of this product than I needed to; I spread it on THICK everywhere there was even a tiny spot of mold. I even put it in places where there wasn't visible mold because I was so grossed out. To be clear, there needs to be a change to the design of frontload washers. We have a 1.5 year old LG machine. We have ALWAYS left the door open after each wash and there is always still standing water in the rubber gasket. I have taken to jamming a washcloth sized rag in there to soak up the water so that additional mold won't grow. I had used at least 4 different types of tablet washing machine cleaners with no improvement. I had also used vinegar, bleach and baking soda. Nothing touched it. This gel WORKED. It smells like bleach, but I really didn't find the smell to be objectionable. We left it on for several hours and it removed the mold completely. The hard part for us was removing the gel once it was time to clean it off. We ran the machine multiple times, wiped it off, ran the machine again, wiped again - it took many, many runs and wipes. That said, I know I used more gel than I needed to and if I'd used a proper amount it's unlikely I would have had this issue. I can't recommend this product highly enough. It was worth the effort and elbow grease and I think it would be compatible with any washing machine out there. Goodbye mold!

Just received this product and tried it for the first time right away. Let me start off by saying it was kind of a pain in the tush to open the container. Yes there is a lid and a seal to be removed...no problem. HOWEVER the nozzle cap in my box had no opening at the tip so it wasn't usable as an applicator right off the bat. I had to get a nail and hammer to "make" a hole on the tip end. I assuming it should have been sent WITH a hole rather than me having to forcefully create one. Second this gel is thick! So thick that I could barely get the product out of the container. It took both hands and me squeezing really hard to get the product out. I cannot comment on how it works as I've just applied it (on my shower grout) so we will see if there is any change in a few hours time. Even if it does work I likely will not repurchase because it was a chore just making the container usable to begin with.

1 - the tippy cap had a screw off top. Do not cut it. (my bad) 2 - it works. my HUMID apt has no ventilation in the bathroom and extremely hard water. The shower has a 1/2 in deep groove around the middle which had significant mold and buildup set in. I had tried making a paste with Comet and using a drill attachment but that barely did a thing. 1 application left on overnight removed 80% of the stain with no brushing (i did use the high powered cleaning setting of my handheld shower head). I'm doing a 2nd application on those tougher spots. 3 - it can be difficult to get this out so I squeezed it into a bowl and used a popsicle stick to smooth it on for the 2nd application. I didn't even notice a smell until I got some on my fingers. Didn't seem any more caustic than other cleaners but I did wash my hands immediately.
