The frequency of window cleaning depends on factors like location, weather, and building type. Generally, for commercial spaces or areas prone to dirt accumulation, a monthly or bi-monthly schedule might suffice. Residential homes may require cleaning every 3 to 6 months, with more frequent cleanings for properties near high-traffic areas or with many trees. Ultimately, it’s best to assess individual needs, considering factors like climate conditions and personal preferences. Regular maintenance not only ensures clear views but also prevents damage caused by dirt buildup, prolonging the life of windows and enhancing the overall appearance of the property.
