Specialized Accessories & Techniques have been developed to create what is called Soft Washing or Soft Wash. This involves the use of a variety of cleaning solutions that is 100% biodegradable to lift and remove the contaminants from siding, roofing and paving materials. The process consists of applying a cleaning solution & then rinsing away the unwanted material while using only LOW PRESSURE. The low pressure is similar to that of a garden hose.
Soft washing is safe for use on dryvit, EIFS, stucco, vinyl, aluminum, wood and just about every other siding material. Trex and other synthetic or semi-synthetic decking materials clean up incredibly well with our process. Black streaks or black roof stains don't stand a chance against a good soft wash.
