2. Use warm water at 30-35℃, then add professional wool detergent, gently stir by hand until foaming, then turn over the inner felt and soak for 5- 10 minute.
3. During the cleaning process, press back and forth with your hands, including gently rubbing, until the foam is clean during the cleaning process. Never rub hard, which will lead to deformation or even damage of the felt.
4. After cleaning, put the felt flat on the table, fold it in half with a soft dry towel, and then squeeze it back and forth by hand to squeeze out excess water.
You can change the towel later. Roll wool and towel into sushi rolls, and let the towel absorb excess water again.
6. After drainage, put the felt in a ventilated place and lay it flat to dry. Don't expose yourself to the sun.
