Chicago’s dense urban environment leads to significant buildup of soot, carbon staining, and biological growth on masonry façades. PROSOCO’s specialty cleaners break down these layers without damaging the underlying material, restoring the original appearance of stone, brick, and concrete.

Many of Chicago’s most iconic buildings—such as those designed by Frank Lloyd Wright or Daniel Burnham—require sensitive cleaning methods that won’t harm delicate substrates. PROSOCO offers tested and approved restoration cleaners used in high-profile preservation projects across the U.S., ideal for restoring landmarks like the Merchandise Mart or the Rookery Building.

Efflorescence—salt deposits caused by moisture migration—is a persistent issue in Chicago’s fluctuating climate. PROSOCO’s products target and remove these unsightly white stains while also helping prevent future occurrences.
