Pressure washing was all it took to clean up this mess on a driveway and garage floor in Peoria, Arizona. This before and after photo shows the difference pressure washing can make to a residential garage with years of built up stains on the concrete. In this photo you can see spills, grease, paint, tire marks, and years of built up grime. Power washing the surface was able to clean up 99% of the stains, even though concrete is like a giant sponge that soaks everything up. We also cleaned up years of built up oil stains, a hard water stain on the front patio, and grease from a barbecue grill on the back patio. Visit our website to see more before and after photos.
