Cleaning Mold off Brick Sidewalk
What can I use to clean the greenish-black mold off my antique brick sidewalk? The bricks are laid on a bed of sand, and there is grass pretty close. I'm worried that a chlorox solution would bleach those antique bricks. Would a vinegar solution work if I am very careful to not allow it to run off into the grass or my flower beds? What has worked for you?
