How can you tell if a nail brush is properly cleaned?

A nail brush is considered properly cleaned when it is free of product residue and has no odors. This cleanliness is essential for maintaining hygiene standards in manicure practices. Product residue can harbor bacteria and pathogens, which not only compromise the health of the client but also affect the quality of the manicure. Additionally, odors may indicate the presence of old products or improper cleaning, which can lead to not just discomfort for the client but also potential infections.

By ensuring that the brush is clean and free of any residue or bad smells, you can guarantee a sanitary work environment that adheres to professional standards. Vibrant colors, the stiffness of the brush, or the brand do not serve as reliable indicators of cleanliness and do not impact the brush's effectiveness in performing its intended function.
