Altgeld Hall at the University of Illinois is getting a glow-up!

As part of the Altgeld and Illini Halls project, masons have been using natural bristle brushes to scrub a gentle, non-abrasive commercial cleaner onto the building's stone to clean it. The goal is to remove the heaviest build up, while not causing damage by using overly aggressive chemicals.

Altgeld’s current dark stone color is partly the result of soot from a coal-fired power plant that operated north of Altgeld Hall.
