Soft Washing vs. Pressure Washing: What’s the Difference?

Think of soft washing as a shower for your exterior. Rather than blasting surfaces with high pressure, it combines a gentle water rinse with an eco-friendly cleaning solution that lifts and eliminates dirt, mold, and algae at the source. The result is a thorough clean that doesn’t risk cracking painted wood, loosening siding panels, or eroding mortar on brick.

Pressure washing is still the right tool for tougher surfaces like concrete driveways and walkways, and we offer pressure washing services for tougher surfaces. For anything on your home’s exterior that’s painted, sided, or made of historic masonry, soft washing is a safer, effective choice.

Our Three-Step Soft Washing Process

We follow a consistent, proven method on each job so nothing gets missed and nothing gets damaged.

Pre-Rinse

Before we touch your siding, we saturate your landscaping with a water barrier to help protect plants and grass from cleaning solution runoff. Then we apply gentle water pressure to the exterior, clearing loose debris and prepping surfaces to absorb the treatment evenly.

Eco-Friendly Treatment

We apply our eco-friendly cleaning solution across the exterior, working it into mold, algae, and built-up grime until they break down. These chemicals safely break down within 30 minutes, so there’s no lasting risk to your family, pets, or the surrounding plant and animal life.

Post-Rinse & Sanitization

We thoroughly rinse the entire surface, flushing away traces of the cleaning agents along with the contaminants they’ve loosened. What’s left is an exterior that’s not just visibly cleaner but sanitized.

Why St. Louis Homes Benefit from Soft Washing

St. Louis summers bring sustained heat and humidity that are ideal for mold, mildew, and algae, so exterior surfaces here accumulate biological growth faster than in drier climates. A standard scrub or rinse moves the surface layer but leaves the root growth behind. Our soft washing service helps address it.

St. Louis also has a distinctive mix of building materials. Historic brick in neighborhoods like Soulard and Lafayette Square, painted craftsman exteriors in the suburbs, and vinyl-sided newer construction all require different handling. Because our teams live and work here, we tailor our cleaning solutions to the specific materials on your home rather than applying a one-size-fits-all approach.
