Our pure water cleaning system uses deionized, purified water that removes impurities, minerals, and contaminants. This water is highly effective at cleaning windows without the need for harsh chemicals. The purified water is applied to the windows and frames and left to dry naturally, leaving behind a streak-free, spotless finish. The lack of minerals in the water prevents streaking or water spots on your glass, making it the most effective and eco-friendly cleaning method available.
