To clean concrete effectively, use a power washer with a pressure rating of at least 3000 psi and a flow rate of at least 4 gallons per minute (gpm). Although higher pressures may be required to remove tough contaminants such as paint and heavy tire-skid marks, most power-washing contractors agree that 3000 psi will do the trick for almost all cleaning jobs.

Once an adequate water pressure is established, flow rate determines the cleaning speed, especially how fast contaminants are flushed from the surface.”You can blast at 10,000 psi, but if you have a flow of only 2 gallons per minute, you’re going to have a pile of mud sitting there,” says Barry Woods of Hydro Pressure Systems, North Hollywood, Ca. Heavily soiled concrete, therefore, requires higher flow rates.
