What must items be before placing in disinfectant?

• A. Thoroughly cleansed
• B. Pre-packed
• C. Categorized by size
• D. Heat treated

Answer: (A)

Items must be thoroughly cleansed before being placed in disinfectant because the effectiveness of disinfectants relies on contact with the surface of the items being disinfected. If items are not cleaned first, organic material such as dirt, blood, or other contaminants can inhibit the disinfectant's ability to work effectively. Cleaning removes these potential barriers, allowing the disinfectant to reach the surfaces that need to be disinfected, ensuring that harmful microorganisms are properly eliminated. This step is crucial in maintaining sanitation standards in nail technology and preventing the spread of infections.
