Answer 7

Depending on the drainage I've always used a pump sprayer with a 50/50 solution of bleach and water. Spray down the driveway with the bleach/water let stand for 20 minutes then wash it off with the pressure washer. It kills all the green molds growing and makes the concrete look good as new
