How to Remove Graffiti with a Pressure Washer

Unfortunately the large blank surfaces of construction sites attract graffiti artists. Removing the graffiti can be time consuming and distract your crew from other jobs. A hot water pressure washer combined with the appropriate power washing chemicals will cut the job time down and produce impeccable results. *You will need an electric pressure washer or gas pressure washer of at least 300 psi and 4-5 GPM, coupled with a rotating nozzle for best results. * Protect your eyes and skin and take the necessary precautions to prevent chemicals from entering the storm drains. * Start power washing at low pressure from top to bottom using overlapping strokes. * Wait a few minutes to let the chemicals act but do not let them dry on the surface. * Rinse thoroughly after you are done.
