when disinfecting pedicure equipment that holds water, once each week, the basin must be filled with a solution of water contain
svetlana [45]

In disinfecting pedicure equipment that holds water, once each week, the basin must be filled with a solution of water containing four cups of bleach for each gallon of water.

The statement is false.

A pedicure is a thorough foot treatment that is appropriate for both men and women. It entails grooming your cuticles, trimming, cutting, and shaping your toenails, exfoliating, moisturising, and massaging your feet, and, if preferred, painting your toenails.

Disinfecting pedicure is  a process that is frequently carried out once every week, and it is finished just before the necessary end-of-day cleaning procedures are finished.

In this instance, the basin must be filled with a solution of water that, according to reports, contains around one teaspoon of 5.25% bleach for every gallon of water.

Therefore, the assertion that the basin must be filled with a solution of water containing four cups of bleach for every gallon of water in order to disinfect pedicure equipment that contains water once per week is untrue.

The complete question is

In disinfecting pedicure equipment that holds water, once each week, the basin must be filled with a solution of water containing four cups of bleach for each gallon of water.

Select True or False.
