Keeping your windows streak-free is crucial for both aesthetics and light penetration. Start by using a high-quality microfiber cloth, as it effectively traps dirt without scratching the glass. Avoid cleaning your windows in direct sunlight; this can cause the cleaning solution to dry too quickly, leaving streaks behind. Instead, opt for a cool, overcast day for the best results. Additionally, consider using a vinegar-water solution for an eco-friendly approach that cuts through grime. Regular maintenance will not only enhance your view but also prolong the life of your windows.
