Exteriors: To do a quality power washing job use the right pressure washer and the right cleaners for vinyl siding. Only use solvents that are approved for pressure washer use.

Apply the cleaner under low pressure with smooth, overlapping strokes. To prevent streaking, start from the bottom and work your way up, don't do too big of an area at once, and let the cleaner sit long enough to do its job.

Rinse away the cleaner but don't get to close. Pressure washers work under high pressure and you wouldn't want to damage anything. Keep the tip of the wand a couple of feet from the wall.

Do not spray water directly at the eaves, gable vents, light fixtures or outlets, and be careful around windows and doors. High pressure can break loose window panes. Make sure to rinse the cleaners thoroughly.
