To clean the outside of windows, use a hose to remove loose dirt and debris. Apply a window cleaning solution with a sponge or brush, scrub the glass gently, and then rinse with water. Use a squeegee to remove the cleaning solution from the glass, starting at the top and moving down. Dry the edges with a lint-free cloth to prevent streaks. For high or hard-to-reach windows, consider professional cleaning.
