Details Soft Wash offers professional residential soft washing services, and we safely clean all types of siding. Contrary to the common practice of many inexperienced pressure wash contractors, our goal is to clean your house using as little pressure as possible. This virtually eliminates concerns of water being forced behind siding, paint being blown off, and water being pushed in around windows and doors. Instead, we use environmentally responsible detergents to gently emulsify surface pollutants and kill mildew. Tough spots are scrubbed and then the loosened “dirt” is rinsed off. Typically our process is to start with the exterior of the gutters and work our way down to the foundation. We remove all surface oxidation, acid rain, general “fall-out” pollutants, and mildew.
