- ARinse the surface with water.
- BClean the surface with soap and water.

Show answer & explanationAnswer & explanation
Correct answer: B. Clean the surface with soap and water.
Before disinfection can be effective, visible debris, dirt, and organic matter must be removed. Cleaning with soap and water physically removes these contaminants, allowing the disinfectant to work properly.
Why the other options are wrong
- A. Rinsing with water alone will not effectively remove all organic debris and may spread contaminants.
- C. Covering the surface is not a cleaning step and would trap contaminants underneath, preventing proper disinfection.
- D. Applying disinfectant to a dirty surface reduces its efficacy as organic matter can inactivate disinfectants.
