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.

Read answers for this question below.
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.
