Laundry-Check to monitor the cleaning efficacy of laundry in washing machines gke Clean-Record® Laundry-Check® ball routine monitoring secures that the previous validation of the washing process remains long-term stable. gke offers six different cleaning indicators for washing machines and washer disinfectants which represent different challenge levels as proof of the cleaning efficacy. It is recommended to test all indicators at the same time together as a preliminary test. The indicator which has just been washed off completely in the validated process should be used for routine monitoring later on. It is advisable to use these indicators in the washing machine in each load to ensure that there are no changes of the process parameters over time.
