Streaks on glass almost always come from three things: too much product, dirty tools and drying in direct sun. Here is the method we use on windows and screens. First, remove loose dust with a dry microfibre cloth, because wiping dust with a wet cloth just spreads grime around. Then use a few drops of neutral detergent in lukewarm water, never a strong degreaser, and apply it with a clean microfibre or a wet applicator. On large panes, work from top to bottom and finish with a squeegee, wiping the blade after every pass. For screens, switch the device off, spray the cloth rather than the screen, and avoid alcohol or ammonia-based products that can damage the anti-glare coating. Finally, buff the edges with a dry cloth so that no drips run back over the clean surface. A common mistake is cleaning in full sun, since the liquid dries before it can be removed and leaves marks.
