Plush dolls can be cleaned using a washing machine, but the following points should be noted before cleaning:

1. Check the doll's washing label to make sure it is machine washable.

2. For plush dolls with electronic accessories or plastic parts, these parts must be removed first to avoid damage.

3. When cleaning in the washing machine, it is best to use a laundry bag or pillow case to protect the doll's surface from being damaged.

4. Choose the soft washing mode of the washing machine to avoid strong rotation and vibration.

5. After cleaning, the doll should be dried in a cool place and patted regularly to maintain its shape and shapiness.

6. For plush toys, using a special cashmere detergent may work better.

Also, if the doll is smaller, consider washing it by hand, using warm water and a neutral laundry detergent. When cleaning and storing plush dolls, the following points should also be noted:

1. Clean the doll regularly to maintain hygiene.

2. Avoid excessive use of laundry detergent and softener, which may remain in the doll, especially for those dolls suitable for children.

3. When storing dolls, overstock should be avoided to avoid deformation, and consider using desiccant to moisture-proof.
