What is the best practice for maintaining nail hygiene during the manicure process?

Switching tools between clients is critical for maintaining nail hygiene during the manicure process. This practice helps prevent the transmission of bacteria, fungi, and other pathogens that can lead to infections. Each client has unique microorganisms on their skin and nails, and by using freshly sanitized tools for every individual, the risk of cross-contamination is significantly reduced.

Additionally, many of the other choices may not effectively ensure proper hygiene. For example, using a standard file alone does not address the need for sanitation between clients, as files can harbor pathogens over multiple uses unless properly sanitized. Similarly, while alcohol wipes can be useful for disinfecting surfaces and tools, relying solely on them without switching tools does not eliminate the risk of contamination. Soaking nails in water may assist in softening the cuticles or nails but does not contribute to hygienic practices during the manicure process. Thus, switching tools is the most effective method for ensuring nail hygiene and protecting clients' health.
