It is recommended to use mild detergent for washing. Put the pillow core in a large washing machine. If the washing machine capacity allows, you can wash two pillow cores at the same time. If you can only accommodate one, it is recommended to add a towel to wash together to keep the water flow balanced. After machine washing, if you dry it, the pillow core will be easier to restore its original elasticity and become softer and fluffier.
