This liquid really does the job. It requires a light scrub with a bathroom brush a few minutes after application

Almost magical, I could hardly believe it.
In a bathroom with mold, we simply sprayed and wiped, and it’s been two months now without it appearing again. Simply an incredible product

It worked well wherever I used it. Porous surfaces are more difficult (e.g. some tiles that have grooves or pores)

This is a magic potion and not just an anti-mold product!!! Five stars are not enough! It cleaned the wall in no time. If you have a serious humidity problem, get it and the result will reward you.

it does an amazing job so far!!! you spray it immediately after you have sprayed and cleaned with the bison mold remover!!!

very good quality from a very good company. it does a very good job. I sprayed this spray on the spots where I had mold and just in case I left it for 20 minutes to work. then I wiped it well and everything turned out perfect. Just in case, I repeated it a second time and everything is perfect.

Very effective!! No scrubbing was needed at all!!
Protective measures, in my opinion, are necessary (gloves, mask, goggles) - especially if there is a problem on the ceiling, where the cleaner may drip after application.
Strong smell - needs good ventilation.

Excellent for PROTECTION against the FORMATION of mold. 2 years after its application, the ceiling and walls in the bathroom have not shown even a single black spot of mold. Now, how everyone in the comments got this product which is NOT a cleaner, but a PROTECTIVE, and cleaned the mold, that is a mystery!

It should be called "Harry Potter's spray," because it really is MAGICAL!! You just spray, wait for 10-15 minutes and then rinse with water, no scrubbing or anything!!! I applied it to the joints of my shower tiles that had gotten moldy and they became cleaner than new! For the more stubborn spots, you can spray again and leave it for another 10 minutes and it's certain that nothing will be left! It has a strong smell (understandable, due to the strong action of the product), so make sure to have a window open if possible and keep it open after use to air out the space.

It didn't do much for the mold, the room needed 10 days with open windows to get rid of the smell. Personally, I wouldn't buy it again. A better solution is to clean it with bleach + a little dish soap + a little vinegar.

I use it in the shower, it removes mold from the grout between the tiles. Amazing result with no scrubbing at all.

I am speechless. It cleans mold from tiles and grout in bathrooms and kitchens, without scrubbing, without effort. I wonder why in one store they told me it’s not for tiles but for walls. It’s my best purchase in a long time

You spray and the mold disappears from the wall. It needs good ventilation afterwards because it smells like chlorine for quite a while.

Five stars are not enough. THE best in its category. As for the smell, the scent of bleach is strong, but personally, it seems reasonable to me; otherwise, it wouldn't be effective. It was used in a shower with a simple rinse at the end, so no gloves or anything else were needed.

perfect product, even for heavy cases!! we needed to spray it 2-3 times with various 40' minutes in between and every moisture, stain, mold disappeared completely, and without even scrubbing it!!

THERE IS NOTHING BETTER! it removed the mold that had accumulated and wouldn't go away no matter how much we pulled it, it essentially melted it away, it came off like jelly from the joints

It is a very good product in terms of effectiveness without much effort, it just loses one star for the very strong unpleasant smell it leaves... I, because I used it only in the shower, the situation is saved if you pour plenty of water after use for rinsing

Removes mold very effectively with one or two passes if the problem is very serious. It requires caution and application with gloves and a mask.

Very good!!!
It immediately eliminates mold.
It is very strong, however, and definitely requires protective measures (gloves, mask, glasses, etc).

It saved me. I cleaned the mold with the red one from Bison, and then I applied this and for 3 months now it hasn't come out at all!

I had never heard of the brand before, it was recommended to me. It does what it promises and completely removes mold

Magical product! It even disappeared mold in the grout of the tiles in my bathroom that other cleaners and chlorine did nothing for! A plumber recommended it to me to clean a table with mold and fungi, and it became completely white!

The mold had spread across the entire wall. With one application, the mold almost disappeared. In the end, with a pass of water and sponge, the wall looked like it had been freshly painted. The wall that was painted with plastic paint became perfect. The ceiling, which was painted with watercolor, not so much.

Very good, I didn't have a big problem but by spraying it and within 10 minutes I didn't need to do anything else, the mold disappeared. Only in one area where the problem was bigger, I rubbed it with a kitchen sponge and the mold completely disappeared, even on a painted wall (dark gray) the color didn't fade at all

I read some good reviews and made the mistake of buying it. I tried to clean two sinks with some salts, but the result was the same as using baking soda with vinegar. I will not buy it again in any case because it's not worth it...

Very effective. It easily removed 2 square meters of dirt from the ceiling. I recommend it, like others, especially for the ceiling, to be used after spraying it on a sponge. In this case, no strong scrubbing is required. The only thing it needs attention for is to avoid contact with eyes, skin, etc., as well as objects.

Incredibly effective. It cleaned a very dirty ceiling in a space that had been closed for 10-15 years with just one application. For applying on ceilings, as another user suggested, it is much more convenient to spray it on a sponge and gently wipe the ceiling with the sponge.

Be careful as it is EXTREMELY caustic. It dripped a bit on my clothes and completely bleached them, as if you had poured acid on them. In a piece of old wood that it dripped on, it discolored within a few minutes. Definitely wear gloves and be very careful with your eyes. Floors/furniture need to be covered because it will damage them if it drips. And of course, wear old clothes to avoid any damage.

The best there is. I have tried several products against mold, but this one left me speechless. In less than 10 minutes, it had completely eliminated the mold.

Very good.
It cleans the mold and leaves no stains on the color.
Even though it fell on a wooden floor, it didn't leave a mark like others say above.
You can spray it with gloves and spread it with your hand.
