ABSTRACT:
A method of testing for sanitization of textiles comprises the steps of cleaning textiles in a water solution and testing the water solution for the presence of contaminants such as adenosine triphosphate (ATP), typically with a luminometer. Typically, the water solution will be drained from a cleaning vessel and tested. Another option is the testing of the water solution extracted after draining such as by a spin cycle. The method provides improved accuracy of test results as to the level of cleanliness. In addition, testing at this early step of the laundering process allows for additional cleaning if needed without having undertaken costly and time-consuming steps such as drying. Moreover, absent re-contamination of the textiles after the cleaning process, drying and finishing procedures may be accomplished without further sanitizing the textiles.
