Mix equal parts white vinegar and water in a bucket (you can also make it in a spray bottle). Optional: add a few drops of dish soap to help cut through grease and grime. Use a dry microfiber cloth to remove dust or dirt from the window surfaces.

Dish soap is a cost-effective choice for outdoor window cleaning because it's gentle on glass and can effectively cut through dirt and grime. If you prefer a natural solution, use a mixture of equal parts white vinegar and water.

Ammonia and Alcohol-Based Solutions Some professional window cleaners prefer ammonia or alcohol-based solutions due to their powerful cleaning capabilities. Ammonia effectively cuts through grease and dirt, while alcohol helps eliminate streaks and evaporates quickly, leaving a clean and clear surface.

The best homemade window cleaning solution is to just mix two gallons of water and about a teaspoon of dishwashing liquid together in your bucket. Some people also opt to use vinegar and water to clean windows. In warm weather, you'll get a little more working time by using cool water.
