Self-cleaning glass is a specific type of glass with a surface which keeps itself free of dirt and grime through photocatalytic decomposition. A nanometer-scale coating of titanium dioxide on the outer surface of the glass introduces two mechanisms which give it the self-cleaning property. Harsh chemicals that are used to clean normal glass are usually washed off into the soil and contaminate it. The use of self cleaning glass eliminates this environmental hazard.
Self Cleaning Glass has a coating of titanium dioxide on its outer surface. Titanium dioxide is an inorganic pigment which is widely used in a several products: everything from sunscreen where it reflects away some of the sun’s UV rays through to toothpaste through to the whitener responsible for the white colour in white paint or even in paper.
Only a small amount of sunlight is required to activate the coating, which ensures that self-cleaning property will function even on cloudy days. A simple rinse with water during dry spells will help keep the surface clean.
