Explanation:

To properly clean and disinfect home surfaces, cleaning (removing dirt, debris) should be done first as disinfectants work best on clean surfaces. Disinfecting first is ineffective if there's dirt, and only disinfecting dirty - looking surfaces misses areas with invisible germs.

Answer:

C. Clean surfaces first, then disinfect them.
