Step-by-step explanation:
When disinfecting pedicure equipment that holds water once a week, it is recommended to empty and clean the water basin. Disinfecting the equipment alone may not remove all the accumulated dirt and debris, which can harbor bacteria and other microorganisms. By emptying and cleaning the water basin, you ensure that any potential contaminants are thoroughly removed before using the equipment again.
