stubborn shower booth mold, GONE

- Reviewed in Canada on June 8, 2025Verified PurchaseThis product is AMAZING! Attached pic is my first try on a strip of black mold in an old shower booth, where I have accidentally made a funny demo of WHERE I applied the gel and WHERE I missed(the squabbily line I drew with the applicator that revealed the white caulking underneath VS. the black mold that got left behind). The effect is that strong and clear to see, and this was a stubborn mold I could not get rid of with other cleaning/bleaching products! It does mean that the gel hardens and sits still pretty quickly so you have to spread it a bit after applying it to ensure maximum surface contact area. Anyway I'll definitely buy again the next time I need mold cleaning!

- Reviewed in Canada on June 11, 2025Verified PurchaseIt’s a simple matter of applying the gel, leaving it sit for prescribed amount of time or longer, wipe it off and your done. Warning wear rubber gloves and don’t allow any of the gel to get on other materials. It does remove those black spots off the rubber seal on the upright wash machine. It worked for me, pricey, but it works.
- Reviewed in Canada on May 26, 2025Verified PurchaseThis ACTIVE Mold Stain Remover Gel exceeded my expectations. I used it on the rubber seal of my front-loading washing machine, and within hours the black mold stains were visibly reduced—some areas looked almost new. The gel consistency is perfect for vertical and hard-to-reach areas since it clings without dripping.
I also tried it on bathroom grout and shower caulking, and it made a noticeable difference after a few hours. I appreciate that it doesn’t have an overwhelming chemical smell, and it feels safe and easy to use.
Pros:
Gel stays in place for deep treatment
Works great on washer seals, grout, caulk, and shower corners
Noticeable improvement in just a few hours
No overpowering smell
Easy to apply and rinse off
Highly recommend if you’re battling mold stains in high-moisture areas. It’s a great targeted cleaner that really makes a difference with minimal effort.
- Reviewed in Canada on June 11, 2025Verified PurchaseThis stuff is like magic! The grout around one of my windows had black Mold spots on it from condensation dripping down the window. After one use, it looks brand new. I expected this product to have a strong smell but I didn’t smell anything until I wiped it off and noticed a light bleach smell (so it smells clean to me). Highly recommend.
- Reviewed in Canada on June 7, 2025Verified PurchaseBest thing ever. I thought i would have to get my washing machine changed by next year. Because of so much mold in the rubber of front load washing machine. I had to do 3 application. 2nd one i left overnight. And now my machine looks day and night. 98% of the mold is gone. Finally i wont feel grossed doing my laundry. Bottle still has 1/3 left i will reapply to get rid of few spots that i missed.
- Reviewed in Canada on May 25, 2025Verified PurchaseThis stuff worked! I had the thickest, grossest, blackest line of black mold on the caulking behind my kitchen sink (from my messy dish washing skills) that was there for years! Nothing worked! I put this on, left it overnight and wiped it off on the morning and it’s 95% gone! And considering how bad it was, I’d say this stuff was a miracle worker!! I’m so so impressed! I plan to do it a second time to see if I can get that last bit of black gone, but either way I’m still a happy customer. I just wish I had taken a before picture!
- Reviewed in Canada on February 16, 2025Verified PurchaseNowhere as effective as a paper towel soaked in full strength bleach, but useful in places like on walls where the paper towel won't stay in place. On floor tile grout it only mildly helped with light mold stains after many hours. It didn't make much of a dent on dark stains. When rinsing off, you get a pile of jelly at the drain that needs to be scooped up. It takes time to remove all the bits since they are transparent.
Overall it underperformed against my expectations. Hard to recommend since it's quite pricey for what it does, even on sale. It can be useful, but not a good value.
I'm going to stick with soaked paper towels for the tough stuff. Just cut into stacked strips, lightly dampen, place, then add bleach on top with a squirt bottle. You can add more as it dries up unlike the jelly which solidifies. Easier to find and remove for cleanup.
I might try another bottle for hard to reach places like vertical grout lines. But you if you have the time, you can also easily make your own with corn starch.
- Reviewed in Canada on June 10, 2025Verified PurchaseWhile I was annoyed on how long it took to come to but I will say that this product works wonders. My goodness the mold was gone instantly after 2 uses. I used it twice now the instructions did say leave it for 3-5 hours. I ended up leaving for 7-8 hour I felt it removed the mold even more

5.0 out of 5 stars Honest Review – This Stuff Works
Verified PurchaseLike many people, I’ve grown skeptical of 鶹 reviews. For the record, I wasn’t paid or asked to write this—just sharing my experience.
If you own a front-load washer, you’re probably familiar with the dreaded mold buildup on the rubber gasket. I’ve tried a few products before, but nothing really worked—until this.
I saw this cleaner in a video and figured it was worth a shot based on the reviews. When it arrived, I noticed it’s labeled for tile grout, and the applicator tip reflects that. It’s not ideal for a washer, so I removed the tip and applied the gel by hand (with gloves).
It had been a while since I really looked at the gasket, and I was shocked at the amount of mold. I applied the gel generously and let it sit overnight. The next morning, the difference was obvious. I did a second application later that day for a few missed spots.
The before-and-after photos speak for themselves—it worked. There are still a few tiny areas I’ll need to scrub with a toothbrush, but that can wait.** I’m sorry I can’t find the before picture
If you try this, be prepared to contort a little to get full coverage around the gasket, and you might need more than one round.
We now wipe the gasket after each load and leave the door open to air it out.
Highly recommend this product and will definitely use it again if needed.

5.0 out of 5 stars YOU NEED THIS FOR YOUR GROSS GROUT !!
Verified PurchaseGET THIS NOWWW!!! this cleaning gel is AMAZING. i loved using it soo much on gross grout that i bought a second bottle the same day i received the first! SUPER. FREAKING EFFECTIVE. wayyy more so than the other products my family has used in the past. and SO EASY TO DO too!!
super easy to use, pointed tip makes it easy to squeeze over grout lines. IMO it's a pretty low-odor product -- no crazy fumes. just apply where you have mold / mildew / discoloration stains you want to get rid of and leave it alone for 3-5 hours before brushing the dried gel away. it's awesome! super effective at brightening up even the gnarly stains we had here.
this was my first time "cleaning" the grout stains and i can't wait to do more!! [fwiw, i'm definitely the opposite of a clean freak lol]
PS: in my excitement, i may have gone a bit heavy-handed with the gel.. or may not have? but keep in mind it is a 7 oz bottle. sufficient for a standard-sized, tiled wall of a shower-tub combo, but if you have a lot of heavy stains, i'd just go ahead and grab two just in case.
- Vicky CReviewed in the United Kingdom on May 3, 2025
5.0 out of 5 stars Definitely recommend!
Verified PurchaseThis stuff is brilliant! Easy to use and no smell. I was skeptical as the mould build up on the rubber seal in my washer was extreme. I left it on for 3 hours and 15 minutes, wiped it off and was in shock! It has left an outline from where the mould was but I can live with that, it looks so much better than seeing black every time I put a wash in. I would definitely recommend this product. Be sure to put it on every mouldy bit as I did miss a few places so will reapply the gel soon
- DonReviewed in the United States on June 10, 2025
4.0 out of 5 stars Don't forget to shake it up as it separates inside the bottle.
Verified PurchaseThe warnings in the instructions say to avoid getting any of this on your skin but applying it you must wear gloves. The spout does not have an opening unless you cut it and then no cap to keep it from spilling or drying out. The product did work on the Washing Machine seal as I brushed it on and let it set then ran the washing machine empty. It removed most of the mold with one application.
