Which item must be cleaned and disinfected after each use in a cosmetology practice?

In a cosmetology practice, it is essential to maintain proper hygiene and sanitation to protect both clients and practitioners. Cleaning and disinfecting tools and equipment after each use is a critical aspect of these hygiene practices. The correct answer focuses on finger bowls, which are specifically used during services involving water, such as manicures or pedicures, and can harbor bacteria if not properly sanitized after each use.

Finger bowls, in particular, come into contact with the client's skin and can collect bacteria or contaminants. Therefore, they must be thoroughly cleaned and disinfected after each client to prevent cross-contamination and ensure a safe environment. While hair brushes and plastic capes also require cleaning and sanitization, the context of the question emphasizes the necessity of cleaning finger bowls after each use to uphold health and safety standards in a cosmetology setting.

In practice, all items mentioned are subject to specific sanitation protocols; however, the focus on finger bowls as a priority demonstrates the importance of attention to detail in maintaining hygiene in a client's personal care experience.
