The answer to 'how to clean window yourself' is to follow these steps for a streak-free shine. First, gather your supplies - a squeegee, microfiber cloth, bucket, and cleaning solution made for windows. Wet the window with the cleaning solution, then use the squeegee to wipe the solution from top to bottom in smooth, overlapping strokes. Dry the edges with the microfiber cloth to prevent water spots. For best results, clean windows on an overcast day to avoid streaking from direct sunlight.
Cleaning windows regularly, about once a month, will help maintain their clarity and prevent buildup. However, if your windows have significant grime, mineral deposits, or damage, it's best to hire a professional window cleaning service for a thorough, safe clean.
