My first concern is it might be stained. I would be careful using a pressure washer. In historic restoration we always go by the rule..The Gentlest method first, I would try cleaning a spot with just a neutral cleaner first. Did you take moisture readings on the concrete? this would tell you if it is still wet. take your time and test, test test

Hi all:

Attached are pics of an entrance, cement, that is supposedly dirtied from watering a flower box directly above the entry. There are gaps in the caulk also. Clean with alkaline and high pressure? Concerned about the age of cement and it being damaged. Help is appreciated.
