The answer to 'how often to clean window' is that most experts recommend cleaning windows every 3-6 months, or as needed. Regularly cleaning your windows helps maintain their appearance, prevent buildup of dirt and grime, and ensures they function properly. The frequency may vary depending on factors like climate, window location, and how dirty the windows get.
For example, windows on the first floor or facing a street may need cleaning more often than second-story windows. Windows in coastal areas or with a lot of tree coverage may also require more frequent cleaning to remove salt, pollen, and other environmental debris.
