Thanks!

Thank you!

Just for the video!

Yes we used SH and a Southeast Surfactant

@@ExteriorMastersAcademy Thank you so much for replying! Are you talking about a Simple Green type of SH cleaner with Southeast's Monumental Surfactant cleaner? I've tried everything from straight bleach to 30% vinegar and can't get the mold/mildew out completely from my AZ. flagstone patio--nothing's working that well.

Is yours a 50-50% solution? Are you near Northern California? I would hire you!
