Hydrophobic glass

A type of self-cleaning glass, the coating on hydrophobic glass essentially repels water. It also prevents most dirt and contaminants from bonding to the glass. The water drops roll together into larger beads (which take up less surface area) and are able to pick up more dirt (both organic and inorganic) as they roll off the glass. The most commonly recognized hydrophobic glass coating is sold directly to consumers as Rain-X®.
