The cleanliness indication system and method include a photoluminescent indicator that is configured to be on the surface of the component. The photoluminescent indicator is configured to be exposed to ultraviolet (UV) light during a UV light sanitizing cycle. The photoluminescent indicator emits light due to exposure to the UV light. The photoluminescent indicator indicates that the surface of the component is clean by emitting the light due to exposure to the UV light.
