How long does it take for anti-freezr to breakdown on concrete, until there's no loner a trace?

soap and water and a scrub brush and go at it and get the stain out. The blue, the green, the red leave stains on cement.  You may have to chisel out the concrete to get rid of it.

A couple of rain storms rinses it off enough it shouldn't bother you. Don't get anal about it. It's a fricken driveway.
