Goodbye to Outdoor Mold!

I used this to remove ugly black mold buildup on the white painted wood railings of my front porch. I've tried so many other products but they just didn't do the trick. I tested this with high hopes from the good reviews I read, and I was pleasantly surprised! I'd say 90% of the test area cleaned right up after applying and letting it sit for about 15 seconds. But this was years of build up, so I'll do a second application and see what happens. I'm very happy with the results already, however. Even using it outside, it still had a strong bleachy smell, but that's okay. I would recommend this for sure.

Fantastic product, almost instantly took off mold

Quickly and thoroughly removed black mold from painted walls inside a closet. Made the basement walls which had a gray mold on them look like they had just been painted when in fact it has been 20 years. Even took mold off a vinyl window shade with no scrubbing or scouring. Still waiting to try it on bare wood but have every reason to think it will eradicate all traces of mold. I am going to be ordering the preventative spray to try after the treatment to help keep from recurring. Very pleased with this purchase and the value. Only drawback is the heavy chlorine odor, but I used a paint respirator the second tie and made sure to ventilate the area well.

Mold remover

I have tried it on some old Molds around the shower and kitchen sink. The effect is amazingly fast , in few seconds it took care of many stains, some old stains required 2 or 3 applications, but this product beats everything else I have tried by far>
