Good as new.

An old pontoon boat was under a tarp that had a very thick layer of mold on it as well as the seats, carpet and the plastic/vinyl walls. The 30 sec mold and mildew cleaner worked like a charm. We did use a broom to get the liquid down deeper into the carpet but it made the boat look new again. Sorry I only have the before picture.

highly recommend!

I could not be happier with this product!! my fence was looking terrible after 3yrs and this stuff has it looking like it was just installed again! spray on, let it sit for a minute or so and rinse off! some spots may need a second spray/rinse but it's really that easy. just ordered two more gallons!

Gold

It cleaned my house like it had been pressure washed in less than 10 minutes. I will highly recommend! I purchased this the day after I had one side of my house, pressure washed, and, I had I known that this existed prior to, I could have saved six hours of running my own water and electricity and could have accomplished this in a fraction of the time. It removed mold, mildew, and green gunk immediately. I did not have to use anything to scrub it, just sprayed it on my house side and and rinsed it three minutes later.
