Soft washing is comprised of using biodegradable soaps and water at a low pressure similar to a garden hose to safely and thoroughly clean your exterior. The soaps are applied with commercial equipment at low pressure to effectively kill the microbes. Once the siding has the solution applied appropriate dwell time occurs then water is used to rinse the house.
Soft washing is a process that maintains the integrity of the building's surface while removing biofilm and microbial contaminants.
The cleaning process needs to be done as soon as possible, as waiting too long will allow the biofilm to become more established and difficult to remove.
