concrobium House & Deck Wash House Cleaner

We rely on this spray every spring to clean off the stains that are inevitably left on our deck from the fall and winter leaves. It takes rigid brushes and some serious elbow grease to give it a good scrubbing, but the difference it makes is very noticeable. My only complaint is that the nozzle/valve is soft of cheaply made plastic, so you'll get some minor leaking and it's easy to break if you're not careful.

Total waste of money. NBC Today Show demo said spray on, wait a few minutes and rinse to clean your house. I did try that. It doesn't work. They said you can spray 30 feet up to 2nd floor. So you can do this without ladders. Well, on full force hose the rinse jet stream gets up there but the wash setting barely reaches top of 1st floor. So you can't get the solution on the upper part of the house. And they left out the part where you must SCRUB with a siff brush. It's in the instructions in the print but in the promotion. This stuff is expensive and ont effective.

Minor algae on pool screens did absolutely nothing. Cleaned some of the floor. One step above dish soap.

Container advertises 2300 square foot coverage. Applying it quickly, I covered about 500 SF before it was empty. In addition, the spray on the "Clean Setting" is extremely weak, barely reaching to first floor gutters. Would never reach to siding beyond ground level window height.

This didn't seem to do much more than pressure washing would have to remove surface dust off the side of painted stucco. Using a foam cannon with soap probably would have been as or more effective.
