We normally use bleach to kill mildew on our roof line and gutters and also on the screen enclosure over the pool. This year we decided to try this product instead. My wife carefully followed the instructions, especially the recommendation to wet all vegetation down before using and then rinsing all plants afterward. Two days after applying this product, any plants and grass that came in contact with it had white spots, dropped their leaves or simply died. This product is the best herbicide I have ever used. I am hoping my plants will eventually come back and the new sod that was damaged will regrow, but my hopes are not high. Our Hawaiian plumeria tree managed to survive twenty years of Florida "cold" snaps, but was no match for this product and quickly shed all of its leaves.
As to the mold: most of the black mold was quickly eliminated, but there is still green mold that has not yet been eliminated after two weeks. Bottom line: this may be fine if you have no plants around your house, and the warning regarding plant damage needs to be much more emphatic. It smells awful, too. So next time: good old cheap bleach.

I have a shed in the backyard and some tree limbs overhang its roof. There got to be a decent amount of moss on the shingles of the shed and I was looking for an easy way to kill and remove the moss. This product was easy to mix in a standard household sprayer and simple to apply. I used the 5 parts water to 1 part concentration mixture since, as you can see in the before pictures, I had a significant amount of moss to dispatch. The mixture wasn't much thicker than water and had no trouble reaching the peak of the roof of the shed using a one-gallon, $15 Roundup sprayer (which I highly recommend) while standing on a ladder to the side of the shed.
I just applied Spray & Forget yesterday so can't comment on its effectiveness just yet. I'll update my review in a few weeks with some after pictures and to see if my rating needs to be changed. As far as the ease of use, it doesn't get much easier than this.

Spray on and you are done. It takes a few weeks to be fully cleaned, but once clean it will stay that way for quite a while. I did my back patio the summer of 2015 and it still is clean a year later.

Rated 5.0 out of 5.0 by Coach Did an awesome job
Easy to mix, easy to use. Sidewalks around the house and an exposed concrete patio were coated with a black moss. The surface became very slippery when wet. I applied this product according to direction and after several rains our sidewalks and patio are clear and clean. I also applied this to our house roof in late fall and after a snowy winter the roof is clear of all moss both green and black. Would recommend the use of this product. Only advise is be patient, after applying you must let Mother Nature do her thing.

Although moss is still visible on roof after several rains it has turned brown and is slowly washing away. I will be using this product on a seat for my motor boat which has mold and hopefully it works as well on that.

Rated 5.0 out of 5.0 by bradburyranch No More Green On White Fences!
Of all the mold removal products around this concentrate is so superior it seems to work as if by magic. It is super easy to apply the water/concentrate mix with a hand pump sprayer (I do not recommend using the water hose attachment - too much pressure and volume wastes material) - no rubbing or other action needed, and in a couple of days all the green and black mold on the poly fences has disappeared. Second great feature is it doesn't hurt your lawn or plants. I apply it twice a year for good, clean - looking outdoor surfaces; and my first jug lasted three years. Third great aspect is no rubbing it in or washing it off - mold control just doesn't get easier!

Rated 5.0 out of 5.0 by kala Worked great. used it on my deck and concrete blocks.
used it on my deck and concrete blocks. My composite deck had some serious stains and my blocks on the top of my garden wall were black. I sprayed both. And have let nature take its course. The deck is greatly improved. One day I was walking by the wall and all the black that had accumulated over 18 years was gone. I wished I had taken pictures.
