Abstract

Disclosed are methods (100; 300) for quantifying the cleanability of a surface (202; 402) of an article (204; 404), 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. The disclosed methods provide solutions for objective verification measures of surface cleanability used to facilitate new article designs, materials, barrier coatings, cleaning processes, cleaners, etc.
