Disinfectants kill all microorganisms, including spores: true or false?

• A. False
• B. True
• C. Not specified
• D. Depends on product

Answer: (A)

Disinfectants reduce or eliminate many microorganisms on surfaces, but they don’t necessarily kill all organisms, especially bacterial spores. Spores are highly resistant and often require a sporicidal product or a sterilization process to be destroyed. In salon sanitation, products are typically labeled to kill bacteria, viruses, and fungi, but not all are sporicidal, so simply using a disinfectant does not guarantee destruction of spores. Therefore the statement is false. Always check product labels for sporicidal or sterilant capabilities and follow the prescribed contact times and usage instructions.
