Disposable items used during a manicure must be disposed of after:

Disposable items used during a manicure are designed for single-use only and must be disposed of after each client to maintain proper hygiene and sanitation standards. This practice helps prevent the spread of infections and ensures the safety and health of both the client and the technician. By using fresh disposable items for every client, you minimize the risk of cross-contamination between clients, which is a critical aspect of maintaining a professional and sanitary manicure environment. It's essential for all salon professionals to adhere to these guidelines to uphold industry standards and protect their clientele.

In contrast, the options that suggest disposals at intervals, such as every week, whenever visibly dirty, or at the end of the day, do not align with the primary goal of ensuring client safety between sessions. These alternatives could lead to increased risks of infection and unsanitary conditions, which is why the practice of disposing of items after each client is the most appropriate and correct approach.
