4. Wrap the hat in paper, try to keep it in this shape for a long time, and dry it in the shade.

Clean wool baseball cap

Then soak the hat in cold water for about an hour. At this time, if the hat is particularly dirty, we can soak it first, and then gently wipe off some obvious stains on the sweater with our hands or a soft toothbrush. Be careful not to rub it, it will damage the wool.

Finally, after soaking the hat, pour out the dirty water in the bucket, and then rinse off the foam and dirt left on the hat with cold water. Then put the hat on a round object with a similar shape to the hat and let it dry naturally, so that it is not easy to deform the wool hat.
