G.P.S. uses 4,000psi pressure cleaners with high flow-rate pumps to ensure a powerful, thorough cleaning. All surfaces are treated with a chemical wash prior to any high pressure cleaning (this kills the mold or mildew and loosens up the dirt). Finally, we clean the surface with high pressure water and rinse it.
