What is necessary to effectively kill germs on surfaces?

• A. Clean with soap and water only
• B. Disinfect and then clean with soap and water
• C. Clean with soap and water and then disinfect
• D. Just spray disinfectant

Answer: (C)

To effectively kill germs on surfaces, it is crucial to first clean the surface with soap and water before applying a disinfectant. Cleaning removes dirt, grease, and debris, which can shield germs from the disinfectant, making it less effective. Once the surface is clean, applying a disinfectant can reduce the number of germs significantly. The process of cleaning followed by disinfecting is essential because many disinfectants require a clean surface to work correctly. The soap and water remove organic matter that would otherwise impede the disinfectant's ability to kill the pathogens. After cleaning, using a disinfectant ensures that any remaining germs, including bacteria and viruses, are effectively eliminated. This two-step process is fundamental in infection control and maintaining a hygienic environment.
