Do you spit your gum onto the ground near Gelman Library?

If the answer is yes, last week your dirty habit put a chunk of change in the pockets of Duane M. Cummins – the owner of Gum Busters D.C. who spent last week scraping chewing gum off the sidewalk near Gelman, who was featured in the The Washington Post.

“When I first did this place years ago, oh my God, it was a mess,” the 49-year-old told The Post. “There was a lot of gum to tackle.”

Next time you want to swap your Trident for coffee before hitting the stacks, remember that the three-part process to remove the sticky substance from sidewalks takes a solution from Georgia, Cummins’ steaming “gum cart” and a power generator.
