Seattle’s Gum Wall lost 2,350 pounds of gum in a massive 2015 cleanup

In 2015, Seattle's famous Gum Wall underwent a massive cleanup operation that resulted in the removal of 2,350 pounds of accumulated chewing gum. The extensive scrubbing marked a significant maintenance effort for the popular public attraction, which had accumulated decades of visitor-left confectionery.

The removal process stripped the brick surfaces clean for the first time in years, resetting the canvas for tourists and locals. Despite the thorough sanitation, the tradition quickly resumed as visitors began re-depositing gum onto the walls soon after the cleaning concluded.
