What is Soft Washing?
Most people know soft wash pressure washing as cleaning a given object using a psi of 500 or less. When cleaning a roof, stucco, or other delicate surface, most people consider this low psi cleaning as non-pressure cleaning. There truly is no such thing as non-pressure cleaning, but with roof or stucco cleaning, the main objective is to wash away all the mold, mildew, moss, and algae away from the shingles, stucco, or other surface without damaging the surface itself. With the roof cleaning procedure, we could actually use a garden hose to wash away these fungi, but it would take an extra 3 to 5 hours to do so. This is why we use specialized tools designed to wash this material away safely, and quickly. With the tools we use, you can see that the so called pressure coming out of these tools are no more than that of squeezing your thumb over the end of a garden hose. With the phrase non-pressure, it’s more a phrase to let you know that almost no agitation is being performed to your shingles or stucco during the cleaning process.
Chemistry is the main element in soft wash pressure washing. In the market today, there is a cleaning solution for just about any surface imaginable, and choosing the right cleaning compound for the surface you are cleaning is the real trick. Many cleaning solutions all but guarantee their product can clean your surface, but many fail to do so and you can waste lots of money on these low grade products.
