Pressure washing techniques and surface safety guide

Pressure washing serves as an effective method for removing contaminants such as oil, grease, mold, mildew, algae, and graffiti from various surfaces. For commercial properties, including loading docks and parking areas, effective cleaning often requires a combination of heated water, appropriate pre-treatment, and controlled pressure to avoid surface damage.

When performing residential pressure washing, caution is necessary to prevent etching or nicking wood and stone. While concrete driveways and walkways respond well to detergents, surfaces like aluminum can dent, and roofing shingles may loosen if treated improperly. For maintenance, electric models are often sufficient for everyday use, whereas gas-powered machines provide the higher power needed for heavy-duty tasks.
