Diluted bleach is a good disinfectant.

• A. False
• B. True
• C. Not sure
• D. Only for certain surfaces

Answer: (B)

Disinfectants destroy disease-causing organisms on surfaces, reducing the risk of spreading infection. Diluted household bleach is an effective option when prepared correctly and given enough contact time. Use the appropriate dilution and follow the label, then keep the surface wet for the recommended duration to inactivate pathogens. It works well on hard, nonporous surfaces and for areas that may have been contaminated with blood or body fluids, but it isn’t ideal for porous materials and can be inactivated by organic matter. Never mix bleach with ammonia or other cleaners, ensure good ventilation, and use a fresh solution each time for proper disinfection.
