The most common myth is that you don’t need window cleaning because rainwater takes care of it. Many people believe that rainwater will naturally wash away dirt and leave windows clean. However, this is not entirely true. Rainwater can actually make windows appear even dirtier by picking up dust, pollen, and other debris as it falls. Additionally, rainwater can leave behind streaks and marks on the glass if it contains impurities. Therefore, relying solely on rain to clean windows is not recommended. Regular cleaning with proper techniques and cleaning solutions is necessary to maintain clear and sparkling windows.
