On Friday. Employees from Cleveland-based Central Window Cleaning dressed up as Batman, Black Panther, Captain America, Spider-Man, Superman, Wonder Woman and others while they cleaned windows at Hoops Family Children’s Hospital. Imagine the surprise as the superheroes rappelled down the hospital’s exterior walls, waving at patients from outside their window and providing a little bit of joy in the process. Following the window washing, the superheroes visited with patients in the pediatric and pediatric intensive care units.
