The best time to schedule your window cleaning depends on various factors like weather, personal preference, and the condition of the windows. Generally, spring or fall are ideal seasons due to moderate temperatures and less humidity, ensuring quicker drying times and better results. However, if your windows are heavily soiled, scheduling cleaning before or after rainy seasons might be beneficial to prevent streaking caused by dirt residue. Additionally, scheduling during weekdays when there’s less traffic and distractions can ensure thorough attention to detail. Ultimately, consider your specific circumstances and aim for a time when weather conditions and your schedule align for optimal results.
