Outdoor - Concrete, Roof, Walls, Headstone, Deck, and Vinyl Siding Cleaner - RTU Outdoor Cleaner Pack of 4

The product works great! I had the North side of my house, front door, garage door and stone back porch covered in green and yellow algae. Applied Citra-shield with a mist sprayer bottle, like you would use for a garden, ortho or something like that, on a dry surface, as dry as it can get with fungus/mold on it. I also had to make sure there was no rain in the forecast, so I waited until the "dry" season to apply the product. I did two coats for each surface needing application and the anti-fungal/anti-algae, with the effects lasting atleast two to three years.NOTE: You do have to spray water on any other vegetation around where you are spraying before and after you apply Citra-shield to dilute any Citra-Shiled that may have gotten on plants or grass you didn't want it to be on. It will kill and prevent growth for areas where it is applied.The Citra-shield is fantastic stuff ans I love the fact it's not toxic. I am very impressed with this product.I applied it a long time ago, but will see if I can find the before and after pictures.

I had high hopes after reading other reviews to find that this product does not work on the fungus that grows on houses located in areas near distilleries . Maybe it works on other things but the attached pictures reveal no change after a very liberal application of this product…
