SoftWashing vs Power Washing

SoftWashing is the science based application of custom blended chemicals to achieve a 100% kill ratio of the stain and damage causing organisms, resulting in long lasting protection and clean appearance.

On the other hand, power washing erodes the surfaces being cleaned, voids warranties and encourages the regrowth of the organisms that eat your surfaces and cause staining.

Here is a comparison of SoftWashing vs. Power Washing:


Power/Pressure Washing

  • Low pressure – pressure low enough to just apply chemicals to kill algae, moss and lichen.
  • Mechanical process of using high pressure (up to 4,000 psi) water to erode off algae, moss and lichen.

  • SoftWashing is safe for soft surfaces such as paints, wood and roof shingles.
  • Power Washing is destructive to soft surfaces such as wood, paint or roof shingles. It is erodes the soft surfaces that are cleaned.

  • Recommended and endorsed by major asphalt shingle manufacturers and American Roofing Manufacturers Association (ARMA).
  • Use of high pressure water voids the warranty on asphalt roof shingles.

  • SoftWashing results in 100% kill of the organisms that cause the unsightly stains and the results last 4-6 times longer than power washing.
  • Pressure/Power washing only blasts off the visible surface growth of the stain causing organisms. It does not kill them. For that reason, and because the root systems remains largely intact the stains tend to regrow thicker and healthier in a zebra stripe pattern within as little as six months.
