Rated 4.0 out of 5.0 by HandymanSailor Worked Well on House, Sidewalks and Boat
My house had accumulated a very noticeable amount of mildew and green mold on two sides. One side worse than the other. This house wash did a very good job on the heaviest side and excellent on the less affected side. Did 2 applications. For rinsing I used only the hose end washer. For the money I thought it did a good job.
With success there I sprayed it heavily on my ugly, moldy, blackened concrete sidewalk. Using a 1300 psi pressure washer I restored the concrete to it's natural color and texture.
Since it worked well there I decided to try it on my sailboat that had begun to show signs of grayish black mildew on the deck. First time using just the hose end rinse. For the second application I used the pressure washer to rinse. Final result was excellent! Deck is clean and white.
I used a total of three 56 oz. bottles for the whole project.
Nine dollars isn't much of an investment. Try it and see if it works for you.

Rated 5.0 out of 5.0 by Academarian Believe the reviews
I'm so glad several people reviewed this and vouched for the product. That helped me determine that I could clean my siding where mold has appeared for less than $20 (two bottles) versus $200 for power washing. It worked very well and it was easy to use. If you have a powerful hose handle, switch that on for the rinse cycle instead of leaving the product on. I was able to pinpoint my rinsing like that to speed it up b/c I have a long hose handle with a power wash setting that is quite effective.

Rated 2.0 out of 5.0 by veener Cleans well but does not have the reach
I bought this because it stated it could reach the 2nd story of the house. When in cleaning mode the highest it would reach is our first story. It was disappointing. To reach our 2nd story I had to get on a ladder still. If I knew this I would have bought competitor version. I will say it cleaned well. If you have a ranch house I would say buy this product.

Rated 3.0 out of 5.0 by SamSeldon Not as good as Bleach
I bought this because my vinyl siding badly needed cleaning and I didn't have time to do it right with bleach. While the application and cleanup were easy, I had to do it twice to get even a fair result - and still there is mold on the house. My biggest problem with it is that the spray - when the hose water is mixed with the cleaner - would not reach the second story of the house. I recommend buying a bleach sprayer pressure tank. One application and once rinse is all it takes and you can hit the second floor from the ground.

I have some mildew on the side of my house which is a painted surface. This product did not eliminate any of the mildew. I treated the area several times and the mildew is still there.

Rated 4.0 out of 5.0 by doer worked well
I wasn't sure which product to buy...tried this one. It worked well getting algae type growth off house, but I DID rub it down with a brush on a pole - if I didn't brush the algae/mold off the house, the spray "killed/bleached" it, but it was still there, although not as green. House looks much better, than not using the house wash. It is a bleach based product and you could smell it while working with it. I made sure the thoroughly wet the plants around before and after. Make sure to wear safety glasses to prevent splashes and drips while spraying and brushing.

Rated 5.0 out of 5.0 by NSN21 Can't believe how good this cleaner is
Long story short... I purchased a house with a 6ft high vinyl fence surrounding the entire yard already here. Fence looked like it has never been cleaned before, or at the very least, anytime in the past 5+ years. Mold stains, dirt stains, you name it. Followed the directions for Mold Armor and it made it look like new. It was truly remarkable. In my case, one coat almost always does it. Wet the vinyl thoroughly, put a heavy coat of the cleaner on it, and be patient - give it the full 10 minutes to sit and do its thing. A few times I got impatient and sprayed it off after 5 minutes and it wasn't quite as effective. Give it the full 10 or even 15 minutes, and hit it hard with water. It definitely needs hosed off with some power. The built in hose adapter on the bottle works great. Highly recommended to anyone needing to clean a vinyl fence, siding, etc.

Rated 4.0 out of 5.0 by Allwet easier than a pressure washer
It worked a lot better than I thought it would. I wish the application sprayer shot further. I didn't reach the second floor. I had to use a brush on the heavier mold and build up but overall it works.
