Oxy-Klenza (2.2lb Container) Environmentally Sensible Cleaner

Does not clean anything. I have brand new travertine in the back yard, which this is supposed to clean. Used as directed, even made a paste to intensify it, did nothing.

Didn't clean the black (tree?) stain on my patio slate

Have mixed feelings about this product. While it works, it does not work like the videos I watched. The concrete was somewhat lighter but very spotty, not at all like I had hoped, used it in three places on property and didn't see fantastic results in any location. Cleaned a 16 x 16 stone in the garden, about 3/4 was lighter and scrubbed the same across the stone, not sure why the results are not better. Would not purchase again, industrial bleach same results and much cheaper. Maybe you need a pressure washer? Not terrible, not great in my opinion

The powder was already hard as if its a very old bottle, i used it anyway, it got rid of some of the mold but not even close to all of it.

Great product!

works well
