Bleach didn't do anything.
Lilly Miller Moss Out For Lawns Concentrate does stain concrete. We recommend hosing off the area oversprayed with Lilly Miller Moss Out For Lawns Concentrate right after the area has been sprayed in order to avoid staining. If this is not possible, Lilly Miller recommends using a product called Super Iron Out to remove stains, which can usually be found at your local hardware store or lawn store.
