    Abstract: A card cleaning apparatus comprises an input bin, an output bin, and a cleaning module disposed between the input and output bins. The input bin receives a stack of playing cards. The cleaning module includes a housing, a UV-C light source, and a card guide. The UV-C light source and the card guide are contained within the housing. A plurality of rollers transport individual cards from the stack along a card transport path. The card transport path extends from the input bin to the output bin via the card guide of the cleaning module.
