Which disinfectant, used before the EPA, is commonly used for surface disinfection and does not require an EPA registration number?

• A. Alcohol
• B. Hydrogen Peroxide
• C. Bleach
• D. Quats

Answer: (C)

Bleach stands out because it has long been a simple, effective option for surface disinfection and was widely used long before the EPA began registering disinfectant products. When diluted correctly, sodium hypochlorite provides rapid, broad-spectrum kill against bacteria, viruses, and fungi on non-porous surfaces, which is why it has been a go-to in many salon sanitation routines. The key is to follow proper dilution, ensure the surface is cleaned first, and observe the required contact time. Always mix fresh, avoid mixing with ammonia or acids, and use in a well-ventilated area. Alcohol, hydrogen peroxide, and quats are also used as disinfectants today, but they are typically sold and labeled as EPA-registered products. The historical note about pre-EPA use is what makes bleach the best match for this question.
