Xero Waterfed Extendable Pole RO/DI Systems

We use multi-stage RO/DI purification systems that strip out contaminants through reverse osmosis and deionization, giving us ultra-pure water for exterior cleaning. That 0 TDS water dries spot-free and streak-free, so every window is left with a flawless finish.

Interior Squeegee Detailing

For interior glass, we use professional squeegees for controlled, hand-finished detailing. This method clears moisture and residue cleanly from panes, edges, and corners for a sharp final look.
