What should I do with the old pillow?

Cut off the old pillow towel, take out the pillow core, put it in a new pillow for use, and then discard the old pillow at noon.

According to the records of traditional culture, at noon, the sun is full of yang, the soul returns to the standard, the evil spirits disappear, and it is unwilling to stay outside for a long time, so it is the most appropriate time to choose to abandon the old and choose the new.
