  • Publication number: 20230077611
    Abstract: Disclosed are methods for quantifying the cleanability of a surface of an article, for instance an aircraft interior component. In embodiments, a solution containing an artificial “dirt” is introduced to a surface under test to simulate a sullied condition. The sullied surface is subjected to at least one cleaning process. Obtained reference and post-cleaning light measurements are compared to determine a measurement difference corresponding to a cleanability of the surface and/or effectiveness of the at least one cleaning process. In embodiments, the measurement difference is assigned a cleanability score for at least one of determining a passing or failing cleanability, modifying the cleaning process, indicating the need for a second or subsequent cleaning, modifying the barrier coating formulation, redesigning the article, etc.
