Name another disinfectant that was used before the EPA and does not require an EPA registration number.

• A. Alcohol
• B. Iodine
• C. Bleach
• D. Quats

Answer: (C)

Bleach fits this scenario because it’s a simple, widely available disinfectant that was in use long before the EPA existed and is commonly sold to consumers without an EPA registration number on the label. When used properly, a diluted bleach solution can disinfect many common microbes on nonporous salon surfaces, following the product’s dilution and contact-time instructions. It’s inexpensive and easy to obtain, which is why it’s often remembered as a pre-EPA option.

Keep in mind its cautions: it can damage fabrics and metals, and it can release harmful fumes if mixed with ammonia or acidic cleaners. Always use it according to the label and in well-ventilated areas.
