One square inch at a time... ain't that the truth! I swear my steps would still be a slip hazard had I started at the top with the pressure washer but n0Ooo I started at the bottom where everyone sees it and had to do the whole entrance. One square inch at a time.
Took me two days and a water bill we're still paying off.
Power washing works too well. Once you do one area everything adjacent to it looks like hell.
Good job, the last thing we want to do is take a spill.
