Pressure washing costs in Little Rock

Sweep it: that's Little Rock Public Works' advice for a dirty driveway. The storm water brochure from its Civil Engineering Division tells residents to water the lawn, not the driveway, since the driveway won't grow, and to sweep sidewalks and driveways clean instead. For other cleaning around the house, it suggests plain mixes, such as liquid castile soap with baking soda or borax, in place of toxic products.

Old brick in the MacArthur Park Historic District comes with a number. The district's design guidelines, dated September 2024, say not to sandblast masonry or clean it with water above 300 pounds per square inch. Damage to the hard outer face of the brick is permanent, they warn, and it lets water in. Hydrochloric acid and similar cleaners are ruled out too.

For dirt, soot, mold and stains on that masonry, the guidelines ask for the gentlest method that works: mild detergents with natural-bristle brushes, water misting, or steam cleaning with water. Oil and metal stains call for non-ionic detergents or a suitable commercial product, and cleaning products should be biodegradable. Before cleaning or stripping paint, test the method on a spot that won't show, to make sure it doesn't discolor or damage the wall.
