    • The dirt and mold are GONE!
Size: 64 Fl Oz (Pack of 1)
Review Image by Joyce G
We recently purchased a house that was built in 1988, It's unlikely the previous owners did anything to their patio other than paint it year after year. This is our first summer here and the patio was absoletly filthy. Even though we are replacing it, we still felt we needed to make it as livable as possible until the re-build is done. This cleaner is amazing. it's easy to use; when attached to your house properly, it does not leak; there is little odor and it's less expensive than other similar products. As you can see from my before and after image, it really gets all the dirt and organic matter cleaned up. Be aware, this size really only cleans an area of around 14'x12'. If you have a larger area, you might consider buying a larger size or additional bottles ... show more

So i was a non believer. One side of our house never gets the sun so it always has grew mildew on the siding. Each year I get a bleach mixture, ladder, long handle brush and go to town.well I read the reviews and have to agree looks so much better. Cleaner to. Sprayed my camper off to. Did a good job with that but didn't get everything like drip stains but dirt and mold gone! Ordering another bottle to do front of our house! Great product and saved me so much work this year! Thank you ... show more

    • Works amazing!!
Size: 64 Fl Oz (Pack of 1)
Living on a lake means constant battles with green mildew, algae, and grime on my siding, and I’ve tried just about everything over the years. Most products either barely work or require tons of scrubbing. This stuff was completely different. I sprayed it on and within minutes I could literally see the green stains disappearing. The siding went from looking dirty and weathered to looking almost new again with very little effort. It saved me a ton of time and honestly exceeded my expectations. If you deal with algae, mildew, or green buildup from living near water or in humid areas, this product is absolutely worth it. Fast results, easy to use, and extremely effective. I’ll definitely be buying it again. ... show more

    • Good results
Size: 128 Fl Oz (Pack of 1)
Used this on my house and garage. Sprayed it on with a garden hose and waited ten minutes and rinsed off with garden hose. Removed 90 percent of the mold spots and dirt. Like the product and worth the money

    • Definitely try this out with aluminum siding
Size: 128 Fl Oz (Pack of 1)
4 stars only because the bleach chemical smell was a bit much in the heat. Other than than this worked AMAZING on my bi level aluminum sided house. Usually I pressure wash but this year im saving my well pump the hassle, and myself. It took a little bit of paint off when you leave it too long but nothing too serious/weather wont recover. Another plus was it didnt kill all my plants beneath it which is a TON (hostas, ivy, fancy grasses and ferns). One of the only products ill be using from now on ... show more

    • Makes for Easy Work of Mildew, Mold and Lichen
Size: 128 Fl Oz (Pack of 1)
Worked great for us on the vinyl siding and window sill caps located on the North side of our home. Mildew and lichen were easily removed with little scrubbing or no required. We used an extendable cleaning brush that accepts a hose to speed up removal of stubborn spots and it worked great for the rinsing as well. Be sure to rinse thoroughly and cover your AC condenser, gas meter and any other metal. ... show more

This stuff really works! I had to have some brick work done on my 36 year old sidewalk so the new mortar showed up like a sore thumb. I tried home armour and was totally impressed with how well it works. I used it full strength in a garden sprayer. It says you don't need to scrub but I did use a deck brush and let it sit a little longer than it said. I ran out right near the end with about 5 ft to go but I'm going to order a couple of more gallons to finish the job and to do some other steps around my house. I also used it on my brick entrance that was black with mold and unable to get a hose to too far from the house. I just used some water and cans to rinse it with. It looks so much better. Highly recommend! ... show more

    • NOT Mold Armor, but it does work
Size: 128 Fl Oz (Pack of 1)
I bought this thinking I was getting Mold Armor. I just assumed that with the exact same packaging that the company had decided to update the name of their house wash. It is NOT Mold Armor, although it does work pretty well. The main difference I found was that it gets used up much faster than Mold Armor. I didn't do a side by side analysis but my impression is that it covered about 75% of what I would expect from Mold Armor. For me it was just as effective. It does cost less, but since I have to buy more it probably even out in the end. ... show more
