    To clean concrete effectively, use a high pressure water jet blasting machine with a pressure at least 15000 psi and a flow rate of at least can achieve a perfect cleaning. Although higher pressures may be required to remove tough contaminants such as paint and heavy tire-skid marks, most power-washing contractors agree that 40000 psi will do the trick for almost all cleaning jobs. Several contractors recommend a power washer with a volume output of 5 or 6 gpm. When cleaning vertical surfaces, higher flow rates are not as critical because gravity helps contaminants flow from the surface.
