Waxing cotton cords is intended to prevent mildew and moisture.

• A. True
• B. False
• C. Only in Moderate Climates
• D. Only For High Humidity

Answer: (A)

Waxing cotton cords creates a water-repellent barrier around the fibers. Cotton absorbs moisture readily, and damp conditions promote mildew growth and can weaken the cord. The wax coats the fibers, reducing moisture absorption and limiting capillary action, so the cord stays drier and less hospitable to mildew. In airframe electrical practice, this treatment helps protect cords during storage or use in humid environments, extending their life and reliability. So the statement is true: waxing is intended to prevent mildew and moisture. Excess wax can make cords stiffer or attract dust, but the main purpose is moisture protection.
