The Great Debate Soft Washing or Pressure Washing? Our answer is both, with our exclusive HybridWash!™ System
Pressure Washing: The use of High-Pressure water spray ranging from 750-5000PSI. These machines have historically been used for nearly 100 years.
Pro's: It's an amazing tool for paint prep on surfaces such as metal or concrete and is often used to deep clean harder horizontal surfaces such as sidewalks, driveways and parking garages. Pressure washing with hot water can remove oil stains, chewing gum, mold, mildew and general dirt.
Con's: It is important to understand that the green and black stains on your house or commercial building are an infestation of microorganisms that need to be properly treated, not pressure washed. When high pressure washing, the surface may appear to be "clean", however the microorganisms are still there and will become visible again in a short period of time. In addition, the use of high pressure (Over 750PSI) can force water behind your siding, damage building materials and even create a bigger problem by spreading the microorganisms around your property. Pressure washing can also damage or destroy soft or porous surfaces such as wood or EIFS/Dryvit.
Soft Washing: The use of a spraying systems to distribute biodegradable cleaning agents to kill mold, mildew, moss and to remove dirt, dust and spider webs. Soft washing started gaining popularity in this industry in the early 1990's. Typically this involves the use of a 12 volt pump, air diaphragm pump or a venturi injector nozzle to apply a chemical to the surface to be treated.
Pro's: This is the perfect tool to kill 100% of the microorganisms without the use of a pressure washer.
Con's: Soft washing alone is not 100% effective at rinsing. Many soft washing companies claim to use a no-pressure method, but this is deceptive. When rinsing is needed they will use a booster pump to increase garden hose pressure from 60PSI up to 180PSI and increase the flow (GPM) by using a buffer tank. With pressure this low, the use of a zero degree tip is sometimes needed, which can easily damage oxidized siding and force water behind siding and into vents and window seals. In addition, these systems rely on the use of more chemicals to emulsify the dirt and treat & kill the growth. This leads to an increased risk of plant damage and chemical exposure
Solution: With over 20 years of experience and over 1000 houses washed per year, we have found that there is no perfect system available on the market when it comes to washing houses and buildings. So we created and developed our own HybridWash!™ System. We have combined the best of both worlds to safely and effectively treat, kill & remove 100% of all mold, mildew, algae, pollen, dirt, dust, carbon deposits and spider webs. After treating the surface the use of a low pressure (200-500PSI) rinse is needed, which can only be accomplished with a custom made pressure washer. Using a very gentle adjustable angle fan tip is needed to remove the loose pollen, dust, spider webs and most importantly the dead mold & algae (aka biological fallout). Our solution is 100% Biodegradable and is safe for your family, pets, plants and the environment.
