Ever wonder why professional window cleaners never seem to get streaks? It's not magic—it's science. Today, we're revealing the professional techniques that make the difference between spotless windows and frustrating smudges.
Understanding the Chemistry
Window streaks occur when minerals and residue from water dry on glass. Professional cleaners use deionized (DI) water, which has had all minerals removed. Without minerals, there's nothing left to form streaks when the water evaporates.
