This gel works wonders!

This gel works wonders. Most products are too weak but this stuff eliminated the black mold where the tile meets the tub. I used in in preparation for selling my condo and I’m sure the new owner will feel much better with no mold in the tub, Highly recommended.

This stuff really works

This stuff really works! And their customer service is excellent as well. The first tube I received was very liquidy so was difficult to use. I called customer service and they had another tube of it on its way immediately. I’m very happy with this product.

Amazing product! It really works.

I kept seeing this ad pop up and the product seemed really convincing. I eventually decided to try it and it really is amazing and works! I used it on our laundry machine and it removed dark black stains that seemed impossible to remove before. I also used it on our window sills, as they are not properly insulated and a lot of mould accumulated there. It removed everything, with the exception of behind the silicone, which makes sense that it wouldn’t be able to remove mould underneath the silicone. I would highly recommend this and purchase again, if needed!

Hi Zib, thank you so much for your kind feedback. We are so happy to hear about the amazing results achieved. In cases of stubborn mould beneath silicone, some customers have found that multiple treatments may be necessary. The effectiveness can vary based on how long the mould has been untreated. Please reach out to our team if you had any questions as we're delighted to help!

Couldn’t be happier!

The order arrived very quickly. I’m thrilled with the squeegee. I will order a backup just in case my husband damages it. It’s easy to use and does the job in our shower really well. Today I tried the glass cleaning cloth I also ordered and wow!!! Just amazing. My mirrors have never been so clean. Thank you for a great product.

Shower mould - Miracle Gel

On fresh new mold (up till 3 months) works after 4-5 hours. On old mold (~3 years old), I did already 6 applications, mold keep disappear layer after layer(become more and more bright), but still holding, each application ~7 hours, shower silicone surface, nothing else worked at all!!! So yes, Miracle Mould Stain Cleaner Gel works, slow.

It really works

It really works, but on some surfaces, like rubber lining, might need to use more applications.

But the product does work.

Works but...

Tried the product on my shower windows and door as per the instructions. Looks like it works but I'm not sure that one application is sufficient.

Worked as advertised

The glass cleaner and circular drill pads worked very well on some well entrenched calcium stains on my shower doors. It even worked on the aluminum frame around the glass.
I haven't tried the nano protector or pads yet.

It actually does what it claims

Well, you want a review now instead of waiting another week so my experience is that the product actually works as demonstrated, however, mold did reappear in approximately 50% of my test areas. The instructions said that some areas might need a second treatment (which I haven't found time to execute) so I intending to do that and base a review on those results.
Here's the deal; so far it delivers on what the promised claims are and I'm impressed. I can only wonder how long it protects or lasts. I opted to get the 3rd tube at the offered discount and so far I haven't regretted getting 3 tubes on my first order.

The gel worked EXACTLY as advertised.

The gel worked EXACTLY as advertised.
Never had a product work that well getting rid of mould and mildew stains.
The only drawback is the very strong bleach odor that lingers for a few days.
Small price to pay for such amazing results.
Still not 100% sure how the grout nanocoat will work.
Had the spray nozzle break in the middle of the job.
Customer service was able to make arrangements to have another bottle sent.
Terrific service.
