How to Clean Moldy Gutters and Bricks


One of my fall maintenance chores that must get done is cleaning off the lovely mold that accumulates throughout the summer on our bricks and gutters. It's not the look we are going for at our house so once a year I scrub it off. This year I decided to work smarter and not harder and save my arms and shoulders days of being sore.

    Be careful with a pressure washer if you have vinyl siding in a bright or dark color. I have seen siding fade to a weathered lighter color if the pressure is too high. Should work great on brick though. Ours really raises the water bill so we use it sparingly.

    I use liquid swimming pool chlorine on my house, concrete walks and patio!! I spray it on with a pump sprayer, let it sit for about an hour, scrub a little in really bad areas & spray with hose, they turn out like new!!! It doesn’t hurt grass either when sprayed with water!! Better than bleach!! Almost a professional cleaner from over 40 yrs of cleaning & from having 6 kids!! 😉😂
