Not all exterior cleaning is created equal. While both methods use water to clean surfaces, they work differently and are suited for different situations. Understanding the difference can help you make informed decisions about maintaining your property and avoid costly damage from improper techniques.
Pressure washing uses high-pressure water (measured in PSI - pounds per square inch) to blast away dirt, grime, and buildup from hard surfaces. Residential pressure washers typically range from 1,500 to 4,000 PSI, which is powerful enough to strip paint, etch concrete, and damage delicate materials if used incorrectly.
Pressure washing is ideal for surfaces like concrete driveways, brick patios, and stone walkways that can withstand the force of high-pressure water.
Soft washing uses low-pressure water (typically 100-200 PSI) combined with specialized cleaning solutions that kill organic growth at the root. These eco-friendly solutions typically contain sodium hypochlorite (bleach), surfactants, and other agents that break down the cell walls of algae, mold, and mildew, effectively eliminating them rather than just blasting them away.
Soft washing is the preferred method for delicate surfaces like vinyl siding, roof shingles, wood decks, and painted surfaces.
We use both methods strategically, applying each where it's most effective. Our technicians are trained to assess each surface and choose the appropriate cleaning method. For most residential exteriors, we recommend soft washing because it provides longer-lasting results without the risk of damage.
