What is the recommended process for laundering towels in a non-commercial setting?

1. Wash in hot water only

2. Immerse in 100 P.P.M. chlorine solution for 1 minute

3. Use laundry detergent only

4. Rinse with cold water

The correct answer is: Immerse in 100 P.P.M. chlorine solution for 1 minute

The recommended process for laundering towels in a non-commercial setting emphasizes sanitization, especially if the towels are used frequently and may harbor bacteria or other contaminants. Immersing towels in a 100 parts per million (P.P.M.) chlorine solution for 1 minute effectively disinfects them, ensuring that harmful microorganisms are eliminated. This method is particularly valuable in settings where hygiene is crucial, such as in kitchens or bathrooms. While hot water can effectively clean and sanitize fabric (which is an important consideration), simply washing towels in hot water alone may not guarantee that all pathogens are removed unless the water is at a specific high temperature and time. Using laundry detergent is essential for removing dirt and stains but might not provide the level of disinfection needed on its own without a bleaching or sanitizing agent. Rinsing with cold water is important for fabric care as it prevents excess wear, but it does not contribute significantly to sanitation. Thus, immersing towels in a chlorine solution is highlighted as a superior method for maintaining hygiene while laundering.
