Cleaning the porch ceiling is a simple task that can be done by anyone with some basic cleaning supplies. First, clean all of the surfaces that will come in contact with the ceiling. This includes the railing, the doorframes, and any other areas that may come in contact with the ceiling. Next, use a mild soap and water to clean all of the dirt and debris that has built up on the surface of the ceiling. Finally, use a dryer to clean any areas that have been affected by water or soap.
