1. Pressure Washing:

• Technique: Uses high-pressure water spray to remove dirt, grime, mold, and pollutants.
• Equipment: Typically involves a pressure washer. It can deliver water at pressures ranging from 1,500 to over 3,000 psi (pounds per square inch).
• Best For: Hard surfaces like concrete, brick, driveways, and patios. It’s effective for cleaning tough stains but can be too harsh for delicate surfaces.

2. Soft Washing:

• Technique: Involves applying a low-pressure water spray mixed with specialized cleaning solutions to kill mold, mildew, and algae.
• Equipment: Utilizes a pressure washer but operates at lower pressures (around 100 to 300 psi).
• Best For: Delicate surfaces like roofs, siding, and painted surfaces. Soft washing cleans while minimizing the risk of damage.
