Which type of tools must be cleaned and disinfected after each use?

In the context of esthetics and hygiene standards, metal tools are typically reusable implements that come into direct contact with clients' skin and bodily fluids. Because of their nature, they require thorough cleaning and disinfection after each use to prevent cross-contamination and infection transmission. Metal tools can include items such as tweezers, scissors, and other instruments, which are essential in providing safe and effective esthetic treatments.

While it's true that plastic tools can also be cleaned, they may not always require the same level of disinfection if they are designed for single use, and disposable tools are intended to be used once and then discarded, eliminating the need for disinfection altogether. Therefore, the focus on metal tools is warranted due to their potential for reuse and the necessity of those tools meeting strict sanitation protocols within the esthetics practice to ensure client safety and compliance with health regulations.
