BALTIMORE (WMAR) -
Childhood superheroes were caught fighting "grime" Tuesday afternoon at the Johns Hopkins Children Center in Baltimore.
Spider Man, Batman, Captain America, Superman, and the Green Lantern left the crime fighting to the police and beat the grime out of the Children Center's windows.
As the superheroes made their rounds, they waved to kids in hospital beds and playrooms as they rappelled down the center's glass window walls.
All superheroes will make a return visit this May to wash the Children Center's windows again.
