The answer to 'window cleaning frequency' is that most experts recommend cleaning windows 1-2 times per year for the average home. This helps maintain a clear, streak-free appearance and prevents the buildup of grime, dust, and other debris. Regular window cleaning can also extend the lifespan of your windows by protecting the glass and frames.
The exact frequency may vary depending on factors like your local climate, the amount of dirt and pollen in the air, and how many windows your home has. Homes in urban or industrial areas, or with many windows, may need more frequent cleaning. Paying close attention to how dirty your windows get can also help you determine the right cleaning schedule for your home.
