Hello! Not sure how to clean this off chick fil A’s concrete. I just cleaned it Sunday and this is the photo today. What is a good chemical to use? I use chlorine, and then a chemical called industrial 500.
Did you use hot water?
Are you sure that’s just not discoloration in the concrete? Looks like it from pic since it’s mainly along edges and joints. Happens if they floated it with a little extra water.

Yeah I used hot water. Yeah didn’t know what was happening because it is clean but then I come back the next day and it looks like this
That’s pretty common. Go google mottled concrete, several reasons it could happen. Not anything you did other than get the dirt off of it that probably obscured it some.
