The gke Clean-Record Level 0 cleaning indicators are used for validation and routine monitoring of bedpan washers and similar applications. Bedpan washers use tap water at elevated temperatures for cleaning. Regionally tap water can contain different ingredients and influence the cleaning process. In addition detergents, rinsing agents and disinfectants are sometimes used as well and may additionally influence the cleaning process. Within the cleaning chamber the spray conditions vary for the following reasons:

• 1. Less spray impact can be found in different areas.
• 2. Loads create spray shadows.
• 3. The interior of bedpans and urine bottles may be difficult to reach and soils may remain

.

By positioning the indicator at different locations in the chamber or on the instruments to be cleaned the cleaning results of those different locations may be detected. The most difficult location should be selected for routine monitoring. The self-adhesive indicator can be adhered at the most difficult area to be washed-off, e.g. inside a bedpan or urine bottle. gke Clean-Record
