You can clean the outside windows in a few different ways. One way is to use a power washer. This machine essentially sprayed water at high pressure onto the windows. It will remove any dirt, grime, or other debris on the windows. Water Fed poles can be used as well. Another way to clean the outside of your windows is to use a ladder and wash them by hand. It is a more traditional way of cleaning windows and will require time and effort. You will need to mix a solution of soap and water in a bucket.
