I first used this product three years ago on my vinyl siding that had extensive mold buildup as the sun never hits certain areas of the house. I know the recommended ratio of water to MoldOff® is 3:1 but I diluted at a ratio of approximately 8:1 because I planned on using a large sponge to spread the MoldOff® on the siding. Plus, to be honest, I was hoping to have the gallon of MoldOff® last for the entire job (I actually used about ½ gallon). I did not use much pressure on the sponge, just enough to lightly scrub the siding. I would do a section, say 4 feet by 8 feet and then rinse with a hose. All of the mold was removed, the siding looked like new and 3 years later I have had no return of mold where I used MoldOff®.

My neighbor pressure washed his house at the same time, using just water, and it did remove the mold but the siding still had a dingy look to it. However, the next year his pressure washed siding again had mold.

Recently I used MoldOff® on some cement sidewalks that had the green tinged mold on it. In the past I pressure washed the concrete, which did remove the mold, but it was returning every year. Plus, the power washing took a substantial amount of time and water. For the concrete I used a solution of approximately 6:1 and liberally applied it with a long handled scrub brush. I let it sit for about 5 minutes and washed it off with a hose, just using house pressure. All the mold was removed and the concrete looks better than the concrete that had no mold.

I highly recommend MoldOff®. I get the concentrate as I can dilute it as I see fit. If you compare the price to some of the products out there it might seem a little expensive, but remember, you are diluting it as you see fit and it DEFINITELY works.

We made a big mistake by storing our foam mattresses in a moist area without a rubber cover. Consequently, a black mildew permeated nearly the whole thickness of the mattresses, some worse than others. Our first reaction was to discard the mattresses as we thought it was a hopeless problem. Just to be sure there was no solution to the mildew problem, we went to the internet. Somehow, we found MoldOff® which we thought should be used empirically before we threw the mattresses out. So we purchased a gallon of MoldOff® and sprayed it on one mattress, lathered it in and let it soak. Then, we sprayed it again and used a thick cotton towel to absorb the excess fluid. We were surprised to see the black color gradually disappear. Some of the stubborn stains we sprayed a third time and rubbed the stains with towels which removed most of the discoloration. What shocked us the most were the unbelievable final results! The foam mattresses remained firm and free of mildew for months and months to this day! We cannot thank the producers of MoldOff® enough for the great outcome.
