What is Soft Washing?
Soft washing is a cleaning process that uses low pressure and specially designed solutions (typically sodium hypochlorite (bleach), water, and a surfactant) to safely remove mildew, bacteria, algae and other organic stains from siding, roofs and other building exteriors. It is termed ‘soft washing’ to differentiate the method from power washing. The Asphalt Roofing Manufacturers Association recommends low-pressure bleach or detergent assisted washing as the approved method for cleaning asphalt roofs in order to avoid damage to the shingles.
Soft washing is best applied using an electric (12v) agricultural sprayer to apply a water-based, biodegradable disinfectant to kill the mold, mildew, bacteria, algae, fungus, moss and lichen on exterior home siding, roofs and other building surfaces.
Soft washing equipment is unmistakably different than power and pressure washing equipment. The electric diaphragm pump applies the cleaning solution at 40-80 PSI (about the same pressure as your standard garden hose). The equipment used for soft washing may also have telescoping handles so that the cleaning solution can easily reach roof eaves, upper story windows, and other such areas, without this added pressure. The benefits are numerous including protection of soft substrates such as wood, vinyl, and caulking around windows.
More than Cleaning
Soft washing is much more than just making your home look like new. The products used by DAPrDAN not only clean stains but also sanitize, penetrate, and eliminate the root of the issue. The main culprit of most roof and siding staining that causes prevalent black streaks is a bacteria called Gloeocapsa Magma. Soft washing has the ability to kill the pest from the root up, achieving a truly clean surface that will last years longer than just power washing.
Clean Siding Improves Home Value
The the damp and dark climate of Northwestern Washington it's common to have green algae on your wood, vinyl or hardy plank siding. Our soft wash cleaning system kills all contaminents and will make your siding look new again. DAPrDAN does not use pressure washers that can cause damage to wood and vinyl siding when cleaning, but low pressure (40 to 80 PSI) to apply our house wash solution.
Power Washing Alone Will Not Last
Pressure cleaning vinyl and wood siding with just water is not the most effective way to clean the exterior of your house. We apply our soft wash roof cleaning mix with about the same pressure as a regular garden hose. We DO NOT blast your home with 4,000 pounds of pressure from a power washer. Companies that use only water to clean your siding are leaving behind millions of active mold and algae spores that will grow back to full bloom in just one season. Our safe and effective house wash will kill these spores on contact, keeping your home clean and fresh for years to come. As an additional service, DAPrDAN also provides an antimicrobial finishing spray that comes with a 3-year no-algae guarantee.
