Prepare the work area by covering plants and turning off exterior electrical outlets and taping down plastic to cover them. Remove any obstacles blocking access to the area, and close all inside doors and windows. Choose a stable work surface or ladder, and wear eye protection as you work.

When selecting detergent for the pressure washer, choose only those intended for use in pressure washing. Apply detergent using low-pressure spray, and switch over to the water-only setting when rinsing the detergent away.

When cleaning brick and mortar, patch any damaged joints, allowing time for drying prior to cleaning. Use low-pressure spray to saturate the brick before applying detergent. When cleaning siding, repair any damaged siding prior to cleaning, and avoid spraying under the panels’ bottom edges. For stucco exteriors, spray the pressure sprayer at a 45-degree angle, and keep the nozzle of the sprayer at least two feet from the surface as you work.
