Turn the power washer's nozzle on the highest setting. Start at a corner of the cement, and spray in a straight line along the cement's edge. When the water shoots from the power washer, it emits in a thin line. As you spray the cement, keep the thin line of water horizontal, so you clean as much surface area as possible.

Hold the nozzle about 3 to 5 inches from the surface of the cement. If you hold the nozzle too closely, you risk chipping the cement. If you hold the nozzle too far away, you risk not cleaning the cement very well.

Spray the cement in slow even sweeps. Allow the water to overlap previously cleaned areas. Overlapping helps provide a second cleaning, if necessary, but it also ensures you do not miss any spots.

Continue spraying the cement until you reach a natural border, such as grass or grout. If you reach grass or gravel, make sure you spray just the cement, or the pressurized water will tear up your lawn or fling gravel. If you reach grout, test the grout on a low setting. High-pressure water can dig up cracked grout and sling it out of the concrete. If the grout remains secure against a low setting, turn the setting up a notch, and continue cleaning. Attempt to spray at the highest setting possible without loosening the grout.

Squeegee the excess water. Once you have sprayed the entire surface of your cement, a thick layer of water will remain. Push it off into the grass.
