To wash house windows, mix water and mild detergent or vinegar in a spray bottle. Use a sponge or cloth to scrub the windows, then remove excess water with a squeegee for a streak-free finish. For stubborn dirt or hard water stains, use a commercial glass cleaner. Clean both the inside and outside of windows regularly to maintain clarity and brightness.
