Hey guys. I was trying to remove a pot rust stain from my concrete patio and spilled the bottle of CLR. I sprayed it down but it looks like it bleached the cement. The cement it regular, unstained, uncolored, unsealed, driveway/sidewalk type finish. The cement was poured 5 months ago and seems to be still curing so it's darker in some areas of the patio than others. Of course I spilled the CLR on one of the darker areas. Any help to fix this would be appreciated. Thanks in advance.
