Rated 5 out of 5 by from Wowza, white house is sparkly! Our 2 story home gets so green on the north side, several times a year my honey will power wash it. Welp, it's been gleaming white all Summer long, and with all the rain we've received in the south, still no green is growing. We are thrilled with this product! Word of caution, when spraying on your house, make sure you don't get it on your rose bushes. Several of our branches that touched the house died off. Also, if you hate frogs like I do, they will no longer be disturbing you on your front porch at night! For some reason, the tree frogs moved their homes back to the ponds and trees after we sprayed our porch. None died, they just hopped off the house :-)

Rated 5 out of 5 by from Easy and it worked Worked as described on air and online--have tried it so far on house vinyl siding and within two days all traces of mold were gone. Next up: trying it on the flagstone patio but no reason to think it won't work there either. Easy!

Rated 1 out of 5 by from Useless This product is pretty useless, I haven’t seen any results using it in my concrete porch or patio. Don’t waste your money!

Rated 5 out of 5 by from Works Great Sprayed it on the black and green buildup and a week later it is gone. Some places I had to spray twice but once it works, it really makes a difference. Siding looks almost new. WOW!

Rated 5 out of 5 by from Great Product Have used it for two years. My husband was very skeptical about if it would work on mildew in Texas, worked great! Follow directions and it does work.
