Cleaning windows is important for several reasons:

1. Visibility: Clean windows allow natural light to enter your home or office, providing a clear view of the outside world. Dirty or streaky windows can obstruct this view and make it difficult to see clearly.
2. Appearance: Clean windows improve the appearance of your home or office, giving it a polished and well-maintained look. Dirty windows, on the other hand, can detract from the overall appearance and give an impression of neglect or disrepair.
3. Health: Windows can collect dust, pollen, and other allergens that can negatively affect the indoor air quality of your home or office. Regular window cleaning can remove these allergens and improve the air quality.
4. Maintenance: Regular window cleaning can help to extend the life of your windows by removing corrosive contaminants that can damage the glass and frames over time.

Overall, keeping your windows clean can improve the appearance of your home or office, help to maintain your windows, and promote a healthy indoor environment.
