For stubborn stains, they might apply a paste made from baking soda and vinegar, letting it sit for a few minutes before scrubbing gently with a non-abrasive pad. Commercial window cleaning chemicals specifically formulated to remove hard water stains are also in their arsenal, providing a more potent solution without damaging the glass.
