What is a potential risk of not properly cleaning nail tools?

Not properly cleaning nail tools can lead to the risk of fungal infections, as unclean tools can harbor bacteria, fungi, and other pathogens. When tools are shared between clients or not sanitized appropriately after use, these infectious agents can be transferred to the skin or nails, potentially leading to infections. Fungal infections can thrive in warm, damp environments, often exacerbated by improper hygiene practices.

The other options presented do not relate to the consequences of inadequate tool cleaning. Increased nail growth and improved nail strength are unaffected by tool sanitation, as these are biological processes determined by factors such as genetics and health. Similarly, the drying time of nail polish is influenced by formulation and environmental conditions rather than the cleanliness of the tools used to apply it. Thus, the proper sanitation of nail tools is essential not only for client safety but also for maintaining the integrity and effectiveness of manicuring services.
