What is Soft Washing?
Soft washing exterior of building surfaces is the safest, most effective way to eradicate any organic growth such as Moss, mold, mildew, algae, lichen from the surface of a home, building structure, fence and almost all other exterior surfaces.

A soft wash system used by a professional pressure washing company will apply pressure through an electric pump. The electric pump usually ranges in PSI of anywhere between 60 PSI and at the maximum 150 psi.
This amount of pressure is drastically different from most levels of pressure being distributed through a traditional pressure washer which usually is higher than 3000 to 4000 PSI.
After the soap is applied at low pressure the technicians then let the cleaning solution sit and dwell to allow the cleaning chemistry perform the washing rather than blasting off the growth with pressure alone. Once the technician allows the cleaning solution to dwell for 10 to 15 minutes on the desired cleaning surface then a high-volume rinse with low pressure is applied.
High volume and low pressure is used to rinse the exterior of the surface after the soap is applied in order to decrease the likelihood of damaging the home or building or Surface to be cleaned. When working in the professional pressure washing and exterior cleaning environment it is imperative to understand PSI and gallons per minute and how those two factors differentiate.
By decreasing the PSI and increasing the gallons per minute the technicians can achieve the same cleaning units out of the equipment used and reduce harm to any surfaces cleaned.
