The Safer Moss and Algae killer seems to be killing the moss between my pavers. However it left behind a white coloring because I didn't read the label (my bad) and you have to rinse and sweep with a push broom after applying. A torrential rainstorm the next day didn't remove the discoloration. I hope a good scrubbing will.

Rated 3 out of 5 by from Modest efficacy Treated a brick patio with product. After treatment and a LOT of scrubbing, there was noticable improvement, but certainly not removal of all the green/black discoloration. Unclear how much good the product did relative to just scrubbing with water. The bottle device works better than some similar attach-to-hose devices.

Rated 4 out of 5 by from Product great - applicator NOT! Being a good steward of the environment, I bought this product fully expecting that it would perform well below the toxic alternatives. Not true. While it didn't kill on contact, it did the job as advertised albeit requiring three liberal applications (4 containers) over 5 days. And I suppose that was primarily because I mostly hosed off the moss from the peak and the edges rather than scraping or power washing as my roof is quite steep and I have no desire to crawl or climb on it. Well worth the investment - job well done. Wish I had a "before" picture but rest assured, they were ready to cancel my homeowners insurance if I didn't clean it up! The hose connect applicator however was far less satisfactory. It leaked no matter how tightly I tweaked it and offered virtually no spray control - all or nothing - meaning I either sprayed a wide field that included windows, trees, power lines, and my neighbors yard or it dribbled drops that landed mostly on me. Next time - and I would buy this product again - I would use a separate spray applicator with more control and range.

Rated 5 out of 5 by from Works Very Well Many cleaning products adversely affect metal around a window, so this spray is effective and safe. The only thing I'd recommend adding is the spray setting mix ratio on the RTU packages because I have places where I need more range and switch to a hose sprayer with a tighter nozzle.

Rated 5 out of 5 by from SO STOKED! Thanks for offering up organic options WE love this product, we use it for our business. Were having the toughest time over the years trying to figure out a good organic alternative to moss prevention. This stuff is it, works great! Ships in a timely manner. Thank you [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Used it on rocks on my waterfall The rocks in my backyard waterfall tend to build up algae and moss and I use this product to help keep it clean. It doesn't do the job 100% but does remove most of the build-up in the waterfall. Just hook it up to your garden hose and spray the area.

Rated 1 out of 5 by from Big let down! This product gave the illusion of doing something with the white residue that it left on the concrete. It was plain to see nothing happened to the algae once the white residue went away a few days later. A waste of time and money, I am sad to say.

Rated 5 out of 5 by from Pavers Sprayed on pavers for moss growing in between the stone. After spraying the next day the moss turned brown and starting dying. Will need to apply one more coat but it worked great.
