Soft low-pressure washing is suitable for materials that could be damaged by high pressures. Most homes, with exteriors made of wood, vinyl, aluminum, or even brick, benefit from a gentle wash using a mild, biodegradable cleaning solution followed by a soft, low-pressure rinse. This method ensures that the surfaces are cleaned without any damage.
High-pressure washing is ideal for more resilient materials like metal or concrete, and is generally used for “flat-work.” For surfaces such as concrete porches or driveways, high-pressure washing may be the most effective. High pressures can remove paint from metal, so it’s standard practice for technicians to perform a test-clean on a small area first to ensure that the surface’s integrity is not compromised.
