Step-by-step explanation:
To remove stains on fingernails, you can use nail bleach or a stain remover designed for nails. Another natural method involves soaking your nails in lemon juice, which has bleaching properties to help lighten stains. Scrubbing your nails with a nail brush while washing your hands can also help remove stains and maintain nail hygiene, especially after activities that may soil your hands. It is important to ensure that the whole hand is cleaned thoroughly, including the area under the fingernails.
Good hand hygiene includes lathering your hands with soap, cleaning the backs of your hands, in between your fingers, and under the nails. For a deeper clean, apply about 5 mL (1 teaspoon) of liquid soap and use a nail brush to remove any debris or microorganisms.
Whether you're preparing food, coming from the restroom, or your hands are visibly dirty, always wash hands thoroughly to ensure good health and reduce the risk of spreading germs. As a part of this routine, also focus on cleaning your fingernails well.
