Which method is NOT approved for drying rope?

When considering the various methods for drying rope, drying on pavement in the sun is not an approved method primarily due to the potential for damage to the rope caused by high temperatures. Sunlight can lead to the degradation of synthetic fibers, reducing the rope's strength and lifespan. Conversely, drying in the shade, using a washing machine (when specifically recommended and under appropriate conditions), and hanging in a well-ventilated area are considered safer options that help preserve the rope's integrity. These methods avoid excessive heat and direct sunlight, allowing for effective drying while minimizing the risk of compromising the material's structural properties.
