The self-cleaning convenience of Pilkington Activ™ Blue has been used in Cleveland, Ohio's Puritas RTA station. Fabricated by Trulite New Berlin, the Pilkington Activ™ Blue used in this public transit facility naturally loosens dirt and gradually breaks down organic residue so that it won't adhere to the glass. An additional hydrophilic action that causes rain to sheet on the glass - carrying away dirt with minimal steaking - keeps this facility looking spotless.
