Bought this to kill moss growing in my shaded driveway....
Bought this to kill moss growing in my shaded driveway. I pulled up the top layer but moss was embedded in the asphalt. I used the 30 minute spray and walk away to kill the embedded moss. It seemed to work well. I will have to do it again in the spring to keep it from coming back. I will also use this on the roof of my summer home next spring.

Did the job in the Pacific Northwest
I have used various cleaners and power washer on my northside concrete patio, always the green algae, moss, etc. would return within a few weeks when it got wet. Last spring I sprayed with 30 Second Cleaner, then power washed, let it dry thoroughly and then sprayed with Spray and Walk Away. It is now 5 months later and my patio looks like it was just cleaned and power washed. No green anywhere.

Kills algae but come back to clean.
I applied the product on the North side of my ranch home (vinyl siding). Knowing that we get our weather from the Southwest, i knew that the north side would not get much rain to rinse off the product. I came back 2 days later to use the pressure washer but it did not take off the now-grayish killed algae. I sprayed a general cleaning product via 2 gallon pump spray on the upper and lower sections. I came back about 20-30 minutes later with power washer and this time the gray algae and grime did come off because grime was now loosened by the different cleaner.
