Diluent is sensitive for bacterial growth. The solution should be discarded if it becomes turbid or infected. If the diluent does become turbid, clean the diluent bottle thoroughly with 50 ml bleach (containing approximately 5% Na-hypochlorite) and 950 ml de-ionized water (=5% solution). Make sure that the container has been thoroughly rinsed after cleaning.
