You’ve Tried Everything.
Nothing Works.
You’ve scrubbed until your hands hurt.You’ve used bleach spray, hydrogen peroxide,
baking soda paste, every “miracle” cleaner on the shelf.
The black mold stains keep coming back. Or worse, they never left in the first place.
Your front-load washer gasket looks disgusting.
Your shower grout is black instead of white.
The caulk around your tub makes your whole bathroom look dirty no matter how much you clean.
Or maybe just move. **There’s a better way.**
Why Everything Else
Failed You
- **Regular cleaners** can’t stick to vertical surfaces. They run off before they can work.
- **Bleach spray** gets everywhere except where you need it. The fumes are toxic. And it barely lightens the stain.
- Scrubbing only removes surface dirt. The mold stains are embedded deep in porous surfaces like grout, caulk, and rubber seals.
actually penetrates & breaks down the stains.
How Our Mold Stain Remover
Works Differently
Our professional-strength gel formula does three things regular cleaners can’t:
- 1Sticks exactly where
you apply it.The thick gel clings to vertical surfaces without running or dripping. Apply it to shower walls, washing machine gaskets, even underneath edges - it stays put for hours while it works.
- 2Penetrates deep into
porous surfaces.The gel doesn’t just sit on top. It soaks into grout, caulk, and rubber seals where mold stains hide, breaking them down from the inside out.
- 3Works while
you sleepApply it, walk away, and let the formula do the heavy lifting. No scrubbing required. Just wipe away the gel and the stains disappear with it.

WOW!!! If I could give this product 100 stars, I would.
I have an old tile shower that had a build up of mold that my maid couldn’t even clean… this stuff cleared the mold out of the grout and caulking. I didn’t even have to scrub anything or put in much effort. I just lightly cleaned my shower, towel dried it, then applied this product. I let it sit for 5 hours and rubbed it off with a sponge and water. Now my shower is spotless and looks super clean! I’m a very satisfied customer!

THIS STUFF IS CRAZY GOOD!
My washer was only 6 months old when the front load protective band started to get mildew and mold and it sucked bc the mold was smooth like it was permanently bonded with the plastic. I tried everything before this. Nothing worked so I tried this. Left it on for 5 hours and it was like the mold was never there. Everything looks brand new and smells great again.

Best Mold/Mildew remover I have ever used
I have been googling how to remove mold/mildew from front loading machine door gasket. Mold and mildew build up in this gasket even if you leave the door open. I tried every home remedies-none of it worked! I got my gloves on and a wet clothe and wiped the entire rubber and took a peak. Wow! The mildew and mold stains were completely gone!! I’m running the washer through a deep tub clean as directed but WOW!! This stuff works!!

Frequently
Asked Questions
Is this just bleach gel?
Yes - the active ingredient is sodium hypochlorite (bleach). But the gel formula is what makes it effective. Unlike liquid bleach that runs off surfaces, our gel sticks exactly where you apply it and penetrates deep into grout, caulk, and rubber seals. You get targeted, powerful cleaning without the waste and mess of liquid bleach.How is this different from a bleach pen?
Bleach pens dry out quickly and contain much less product. Our formula comes in a 7oz bottle that treats multiple areas, and the gel stays wet and active for hours while it works. You also get a precision nozzle for targeted application.Will this damage my surfaces?
No. It’s safe for grout, caulk, rubber seals, tile, and hard surfaces. It’s specifically formulated for these applications. However, it will bleach fabric, so keep it away from towels and clothingHow long does it last?
One 7oz bottle treats approximately 25-30 linear feet of grout or caulk, or 3-4 full washing machine gasket treatments. For most bathrooms, one bottle is enough for multiple applications.Why didn't it work for some people?
In nearly every case where the product “didn’t work,” the surface wasn’t completely dry before application, or too thin of a layer was applied. Follow the instructions exactly for best results.Does it remove the mold or just the stains?
It removes the visible black stains caused by mold. For active mold growth, you’ll need to address the source of moisture. This product makes the stains disappear so your surfaces look clean again.What if I'm sensitive to strong smells?
The formula does have a bleach odor. Always use with good ventilation—open windows and run fans. If you have asthma or chemical sensitivities, wear a mask during application and leave the area while it works.How do I get the gel out of the bottle?
Shake well for 10 seconds before use. The gel is thick by design. Squeeze firmly near the nozzle. If gel has settled, use a Q-tip to break the surface tension in the nozzle opening
