Soft washing revolutionized the roof and exterior cleaning industry by allowing more carefully metered chemical solutions to be applied to building surfaces for the benefit of cleaning that surface chemically without pressure. Because of that, in the last two decades, soft washing has become the most important change to the mobile exterior cleaning industry, since the downstream injector.
A soft wash incorporates special low-pressure nozzles on the end of a pressure washing gun or wand. That’s combined with a biodegradable chemicals that remove the biological elements (mold, algae, pollen, dirt, moss) and other stains without damaging surfaces on your home or killing your plants.
Water used to soft wash your home will be under 500 psi. Rather than relying on pressure to clean your home, soft washing uses formulated detergents and “dwell time” to clean those surfaces. The main benefit of the soft wash is how delicate it is. Unlike high pressure washing, you won’t need to worry about chipping paint or shooting asphalt off your roofing shingles because there won’t be enough water pressure to do so. PRESSURE WASHING DOES NOT KILL THE ORGANIC SPORES and WILL BE BACK IN NO TIME! Soft washing fully breaks down bacterial particles that help mildew cling to your roof, siding and other exterior surfaces. The fresh curb appeal will stay for much longer.
High pressure cleaning should be reserved mostly for hard surfaces like concrete, brick and treated lumber decking boards. Many paint ready projects utilize high pressure cleaning to remove loose paint, this is about the only reason to force high pressure onto a home or building facade. a few things that would call for a pressure washing.
Removing loose paint from wooden or aluminum siding.
Preparing wooden or aluminum siding for paint.
Preparing decks for staining (removing grayed out wood fibers and loose stain/paint).
Washing concrete that is over three years old.
