What do professional window cleaners put in their water?

We mix clean water with a small amount of high-quality dish soap, often Dawn, to break down dirt, oils, and fingerprints. At GoldenHome Window Cleaning, we've found the soap helps our squeegees glide smoothly and reduces streaks across the glass. We also use purified or deionized water, especially for exterior windows, because it dries without spots or mineral marks. In hot Topeka summers, we sometimes add a specialty product like Hislide that helps water evaporate more evenly so fewer spots are left behind. Our goal is a solution that's gentle on glass and frames yet strong enough to deliver a spotless, high-end finish for homes and businesses throughout Topeka.
