Wahkon, MN – Soft Wash Cleaning Project We soft washed these homes in Wahkon, Minnesota, which were covered in mayflies. Before starting, we researched the exact stain and finish used on the siding to ensure a safe and effective cleaning. By following the manufacturer’s guidelines, we were able to remove the buildup without causing damage to the surface. Another job done right — clean, protected, and looking brand new! What is Soft Washing? Soft washing is a low-pressure cleaning method that uses specialized solutions to safely remove dirt, algae, mold, and other organic stains from exterior surfaces. Unlike power washing, which relies on high pressure, soft washing protects siding, paint, and finishes while providing a longer-lasting clean.
