Removing Green Algae from Concrete Steps and Driveway?

A couple of years ago I asked how to remove green algae from my concrete steps and driveway. Someone recommended a solution of vinegar and something else. Unfortunately, I forgot the something else. All I know is that it worked. Please help. Thank you.

You could use vinegar straight or mixed with water. You could also try bleach and water in a ratio of 2 parts bleach and 1 part water or any ratio. Be sure to wear eye protection around bleach. And you might have to scrub the moss and algae with a brush. You could also try pressure washing but not with bleach. Or try some products made to remove moss and algae from a big box store.

I had algae on my concrete patio. I sprinkled the green area with baking soda then sprayed vinegar over the area covered in soda. I waited about 15 - 20 minutes and scrubbed it with along handle (deck type) brush. Occasionally rinsing my brush in a pail of water, I could see the green algae in my rinse water.


Finish by rinsing with a water hose or buckets clean water.

Enzyme cleaner, even for puppy urin; it should come with a concentrate, gallon jug and a smaller spray version that you hook the hose up to allowing you to spray the perfect ration all over your surface.

Whats fabulous about using enzyme cleaner? Everything! Its harmless, practically digestive enzymes that break down organic material, such as pet urine, mold, fecal stains.... spray generously in the am and by the time the sun dries it all away, your pool deck, drive way, ROOF TOP whatever will be white. Or st least should be. Sand isnt organic material, but the nasty stuff, including the mold, get eaten away.
