The answer to 'how often to clean window' is that most experts recommend cleaning windows every 6-12 months. This helps maintain clarity, prevent buildup, and keep your home looking its best. Regular window cleaning removes dirt, dust, and grime that can accumulate over time, especially on exterior windows exposed to the elements.
The exact frequency may vary depending on factors like your location, climate, and how often the windows get dirty. Windows in high-traffic areas or exposed to more outdoor pollutants may need cleaning more often, such as every 3-6 months. Cleaning your windows at least once a year is generally considered a good baseline to keep them looking their best.
