Self-cleaning glass

The latest sheet glass trend is self-cleaning glass. It works according to a very simple principle. Organic dirt is broken down by the ultraviolet light in sunlight, which makes it easier to remove. When it rains, the broken down dirt is simply washed off the windows leaving almost no streaks because instead of forming droplets as it would on conventional glass, the water forms a film which covers the entire surface of the glass and takes the dirt with it as it runs off. This is the reason why self-cleaning glass offers better visibility than conventional glass when it rains.
