Dealing with Colorado's Hard Water Stains on Your Exterior

Much of the Denver Metro area has notably hard water, meaning it carries high concentrations of calcium and magnesium minerals.

When hard water evaporates on windows, siding, or concrete, it leaves behind a cloudy, chalky mineral residue that regular rinsing won't remove.

Professional-grade cleaning solutions formulated to dissolve mineral deposits — combined with proper technique — can restore surfaces without scratching or etching glass.

Regular cleaning prevents hard water deposits from building up into permanent etching, especially on windows and glass railings.
