Use the sun's UV rays to loosen dirt so water can rinse it away. Your windows will stay cleaner longer and will clean easier. The titanium dioxide layer on Neat glass reacts chemically with the sun’s UV rays causing organic materials on the glass to decompose. When it rains, dirt easily washes away. A thin layer of silicon dioxide makes Neat glass exceptionally smooth and hydrophilic. This allows water to disperse evenly or “sheet off” and evaporate quickly, greatly reducing water spotting.
