More natural cleansers, like borax, did nothing to clean the mold growing along the edge of my shower. Time to get serious. This stuff is magic. I like that it’s easy to apply so I could put it only where I needed it. A few hours later I wiped up the gel with a paper towel then went over it with a wet sponge. Mold GONE. In hindsight I wish I’d put it on all the grout in my shower because where I used it looks pristine. It does smell of bleach so be prepared to turn on your exhaust fan for a few hours while it works.

I was pleasantly surprised by how well this mold stain remover worked. It did exactly what the product description promised—quickly and effectively removing mold stains with minimal effort. I applied it to some stubborn stains, let it sit for a bit, and wiped it away with ease. The results were impressive, and I didn’t have to scrub too hard. The only downside is that the smell is a bit strong, so I’d recommend using it in a well-ventilated area. Overall, a great product that delivers on its claims!

The Mold Stain Remover Gel Cleaner by ACTIVE is a solid product for tackling stubborn mold stains, especially in tricky areas like front-loader washing machine seals. The gel formula is a big plus—it stays in place, which makes it much easier to target specific spots without dripping or wasting product. After applying it to the problem areas and letting it sit for a while, the stains were noticeably lighter, and with a bit of scrubbing, most were gone. It’s not an instant fix, though. For deep or long-standing stains, you may need to reapply and give it more time to work. The smell is a bit strong, but it’s tolerable and fades quickly. Overall, this cleaner is effective, easy to use, and a great solution for maintaining a clean and fresh washing machine and bathroom. Just be prepared to put in a little extra effort for tough stains.

This stuff is like magic! If you’re looking for something to get rid of mildew or mold spots this is it!! Put the gel on it, leave it on for 3 hours and just wipe clean and it’s GONE. Great value, use gloves to apply it and remove it, the smell is harsh it’s like bleach sort of smell, great size, you can get a lot of use out of one bottle. No leakage whatsoever, packaging was great. Overall great quality product.

I have tried to use many things to get the stubborn mold stains off my shower and walls and nothing seem to be working I even tried boat hull cleaner and that didn't work so I was skeptical at first but let me tell you that this is the best product and it returned everything back to White I couldn't believe it ,I highly recommend. Smell is strong! Air out area!

I have a front loading washing machine and the mold build up around the rubber casket was SOOOO awful, I wanted to ditch the machine for a new top loading washer. A friend told me about this product and wanted to give it a try. It took 3 treatments to get the area totally clean and I'm amazed. This will be a stable in my laundry room. Amazing product!!

I purchased this product after doing extensive research on products to clean the inside of my washing machine font loader seal and came to this product. It’s basically “Clorox bleach” in a gel form. The gel form allows the bleach to stay suspended on the mold for a longer period of time then simply spraying it with a liquid.. However, the first time I used this product on my washing machine seal, I made sure to leave it on there. It was a little longer than the five hours stated on the bottle I applied the night before I went to bed and it was dried on the washing machine ring so I had to run a few cycles to get it to come off. I would say it did a 15% job at removing the mold and mildew off of my washing machine seal. However, it became much cleaner after applying the product a second time alongside “Clorox Tilex, mold and mildew remover” mixed in. The front loader seal is about 60% of what it used to be, so it has gotten cleaner. Overall, Does this product say when it says it does?…. Possibly. But you’ll have to go through multiple bottles of this product not just a one and done thing. I would say my testing of the product is fair. The washing machine is over 10 years old and the seal has never been deep cleaned before. The container is over halfway gone in the seal isn’t clean yet as others have shown in pictures..

I didn't take a before photo because I was a bit skeptical even with the other reviews. But this stuff really works-- we had a big mold stain on the corner of our tub that would not come off with bleach, baking soda solution, etc. We were convinced it was there to stay but it left the tub looking dirty no matter how much we cleaned it. I followed the directions and put it on first thing in the morning; within minutes I started to see the mold stains start to turn from black to a dark grey. After 5 hours the stains were completely gone and I'm not even exaggerating! Tub looks like it did when we first got it. Will continue to buy this in the future!

I figured i would try this for my front load washer and it blew my mind!!! It removed 98% of all mold and mildew stains!! Now I don't have any funky smell in my washer or on my clothes!! I highly recommend this product 👌 👏

Wow. This worked so well. It got 99% of the mold from the washing machine. Easy to apply. I applied once, waited 3 hours, then gave it a scrub. Where there was still some black applied some more. Waited an hour. 95% gone. Then one more time applied in some small parts, then waited an hour. After that it’s almost all gone. I wiped it all out and then put the machine on cycle. It smells and looks amazing. Definitely recommend.

Works amazing! My washer door seal was so nasty with mold & mildew. I’d previously tried many other cleaners, but with no success. The stains were old, so ended up using for 2 rounds, waiting overnight before wiping clean. My door seal doesn’t look brand new, but a definite noticeable improvement. The cleaning gel is pretty toxic stuff, so make sure you have gloves and a mask on-hand.

Condo rental shower update. The tub and walls were not in good shape. Lots of mold everywhere: caulking grout and even the shower head! I spent 40 min applying it. Waited for 1 hour ...I probably should have waited two hours or more.... i came back and scrubbed with a brush and 95% of the mold was gone. Now I couldn't smell anything g for the rest of the evening but it was worth it. Place looked really good. Some really embedded black mold was stuck in the caulking but what can you do? This did a great job. ****** Always thought these gimmicky products were filled with empty promises. I have renewed faith. Like another user said..the bathroom smells like a swimming pool for awhile but the mold is gone! I have a curbless shower and the corners were starting to yellow and some of the caulking started showing black. I followed the instructions. Used 50% of the bottle on one application. Keep the fan running. Let it dry after 3 to 5 hours . Wipe away with gloves and some towels or paper towels. Voila! It works very well. Yellowing grout lines became white again. Transparent caulking transparent again! I have a rental condo and now im going to go test it on that tub (ewww) and that will tell whether this digs in deep to get rid of the mold.

Just amazing. Did a great job cleaning the inside parts of my washing machine that had mold. Wish I had a before and after picture to share. I tried multiple times to clean before I bought this and nothing worked. Took a few hours and a couple rounds of application. Highly recommend.
