Correct PSI for my home’s siding?

Is 1800 PSI enough? Actually, the amount of psi required for building materials is different. Wood siding that is painted, soft-grain stucco, aluminum, and sidings are best treated using 1200-1500 psi models. For stucco that’s delicate siding, it’s recommended to choose an angle of 25 to 30 degrees greater spray nozzle, which distributes the water over a larger area and uses less force, thus avoiding any damage or nicks. When cleaning vinyl siding or other tough unpainted surfaces like brick, stone, and steel, you should make use of a machine that is rated for up to 3,000 psi.
