Hello I'm new to the forum good stuff here .... Question I have is does anyone use dish soap in there concrete pre treat? ... I currently use 12.5% SH at a 30/70 mix with water... I have a new to me skid sprayer for roof and concrete... Just wondering if anyone has seen any difference using say dawn like I do in my house wash mix.. I live in Alabama so we always spray the SH/water before we use the surface cleaner ... Also do any of you spray SH after using surface cleaner and not rinse it off?.... Thanks
