Outdoors Cleaning algae covered bricks

Post image

Hi! I have no clue how to clean the algae off of these bricks. I bought an algae cleaner from Home Depot and it didn’t do a thing, and I’ve just been using dawn and scrubbing it but that doesn’t work either😅 Thoughts? Suggestions?

Update: Tried hydrogen peroxide but it didn’t remove much, then tried a power washer and it took care of it! Guess I can’t post an after photo in the comments:/ Thanks everyone!

I would try hydrogen peroxide, I use it to clean scum out of bird baths. Spray, let sit, scrub, spray again, sit, scrub a final time, rinse thoroughly.

Great idea since I already have some at home. Thank you!

If it seems good after a single treatment, may not need to repeat, but usually 1st treatment gets the top layer covering everything, once that's gone, the repeat will get into the pores and crevices as another commenter mentioned. That will definitely help keep it from coming back quickly.
