Which type of nail tool should be disinfected after each use?

The appropriate answer emphasizes the necessity of disinfecting metal implements such as cuticle nippers and files after each use. This is crucial because metal tools can harbor bacteria, fungi, and viruses that could potentially lead to infections or other health issues if not properly sanitized. Disinfecting these tools between clients prevents cross-contamination, adhering to stringent health and safety standards in the salon environment.

In contrast, disposable files do not require disinfection since they are intended for single-use only and are discarded after use. Plastic nail buffers and rubber cuticle pushers may have lower risks of transmitting pathogens, but they are not as commonly disinfected as metal tools due to the materials they are made from. It's essential to maintain proper hygiene practices with tools that have prolonged contact with skin and nails, reinforcing the correct choice in prioritizing metal implements for regular disinfection.
