re: Driveway/Concrete cleaner when pressure washer isn't available

Get a pump sprayer and some concentrated bleach. Mix a solution with water and spray off the whole thing. Let it sit for a good 30 minutes and then wash it down.


Now, do the same thing with a pressure water later on and it will come out looking white as a ghost.

Let the bleach do the work for you each time. Don't rush letting it sit.
