During the washing process of this vinyl siding, a powerful cleaning solution is applied to the exterior of the home, which helps to break down and remove any dirt, grime, or other contaminants. The solution is then rinsed away using a low-pressure stream of water, leaving the home looking clean and refreshed without any damage. After the washing is complete, it's important to inspect the exterior of the home to ensure that all areas have been thoroughly cleaned. Any remaining stains or marks can be addressed with spot cleaning or additional washing as needed. The homeowner said, "You make it so bright that I cannot look." smiley.
