What is Powerwashing?
Powerwashing is the application of high pressure water spray to a surface. The spray, generated by portable pumps and mixed with a special combination of water and washing detergents, can be as powerful as 4 to 6 GPM (gallons per minute flow rate), 1,500 to 3,500 PSI (pounds per sq inch pressure) and up to 200 F. By comparison, an average powerwasher can produce a spray that is over one hundred times more powerful than your typical garden hose.
