What is PSI?

Pressure washers are actually extremely powerful hoses that spray out pressurized water jets. This pressure can be almost 100 to 200 times the pressure of air, i.e. more than 1500 to 3000 pounds per square inch. This measurement is known as PSI. Whether a pressure washer is safe for your car has to be determined by its PSI factor.
