Hi, Well, I'm guessing the concrete is just dirty so just use your hose with a hard spray nozzle on it. It's okay to use a mild soap on it, too - you know we wash our cars in the driveway and that amount of soap doesn't hurt the lawn!
The pressure washer works if you use the surface tool...it eliminates the stroke and swirl of missed areas...when wet they all look clean...quick easy way is to use a chemical ( yard safe)...I use both...pressure wash everything..drive, sidewalk, wood fencing etc...
I use Wet n Forget spray on my shaded sidewalks to lighten them up. Check it out!

try a pressure washer :)
Try power washing once a year. It should prevent the build up.
Wet and forget spray wash .no Pressure washer required. Follow the directions on the bottle
