Final answer:
Nail cleaning before polishing involves using a nail brush and liquid soap for at least 20 seconds, focusing on the skin under the fingernails and commonly missed areas.
Step-by-step explanation:
Before polishing nails, it is essential to clean them to remove debris. Cleaning your nails can be done effectively by using a nail brush, which should be used in conjunction with liquid soap to ensure all dirt and microorganisms are removed, especially under the fingernails.
For at least 20 seconds, about 5 mL (1 teaspoon) of liquid soap should be applied all over the hands and arms, paying special attention to the most commonly missed areas during cleaning, such as the thumb, wrist, areas between the fingers, and skin under the fingernails.
In addition, removing debris before a manicure is crucial to prevent health risks associated with bacteria or fungi being sealed beneath nail polish.
Nail products often contain toxic chemicals like dibutyl phthalate (DBP), toluene, and formaldehyde, making this cleaning step all the more important to maintain nail health. In professional settings, nail technicians are required to have specific training and certification to ensure safety and hygiene practices are upheld during nail treatments.
