1. First, prepare the wool to be ironed and a large enough container, and put the wool into the container. Boil a pot of boiling water and slowly pour it into the container.

2. Secondly, gently stir the wool with chopsticks or other tools to make it heated evenly until the wool is completely soaked in hot water. Let the wool soak in hot water for 10 to 15 minutes.

3. Finally, take the wool out of the hot water and rinse it with clean water to remove the residual hot air and impurities. Squeeze the wool, dry it or dry it with a towel. Scalded wool can be used directly or rolled into wool balls, which is convenient for use and storage.
