After handling clients with any skin disorders, attendants must immediately disinfect their hands using what method?

The correct answer is washing with soap and water. This method is essential for ensuring proper disinfection of hands after handling clients with skin disorders. Hand washing with soap and water effectively removes contaminants, including bacteria, viruses, and any pathogens that may be present after contact with clients.

While alcohol-based sanitizer is widely recognized for its antiseptic properties, it is less effective when hands are visibly soiled or contaminated. Wet wipes can provide a quick clean but do not effectively disinfect in the same way thorough hand washing does. Rinsing with warm water alone does not achieve the necessary level of cleanliness required after potential exposure to skin disorders. Thus, the most effective and recommended method for ensuring hygiene and preventing cross-contamination in a cosmetology setting is washing hands with soap and water immediately after client interactions involving skin disorders.
