IWCA Developing Glass Cleaning Standard

The International Window Cleaning Association (IWCA) is developing a "Standard Practice for Cleaning Architectural Flat Glass" through ASTM International, an international organization that develops and publishes technical standards.

The standard is designed to assist window cleaners with identifying the most effective methods to clean, restore and preserve architectural glass, says Paul West, IWCA glass chairman.

In addition, the standard will cover removing various glass stains and the challenge of cleaning glass left unprotected during new construction.
