There is only one 3D glasses cleaning machine on property, and it's behind the Imagination Pavilion. Part of the rotation for the Imagination CM's is to clean glasses from every attraction on property. They are sent to the location via a truck every morning and sent out every afternoon. Their sent through a giant car wash basically. They get rinsed with soap and water, then get washed with water, then dried. I forget the temperature the water is, but it's at least 100 degrees.
