The new regulations are going to just directly lead to classrooms getting more plain and sterile, a trend that already has been hastened by numerous other policies. 

"When used by children, the center shall wash stuffed animals, cloth dolls, dress-up clothes, and pillows or removable covers, at least once a week or when soiled"

. Removing all covers, along with washing all the other soft materials, is going to make maintaining soft items in the classroom exponentially harder. Students will have less to play with. Even if those items were substituted for other items that aren't soft, it's still going to end up depriving them of new sensory experiences, comfort from a soft toy, and lots of imaginative play. Not to mention that even if centers are able to keep up with those cleaning requirements their materials would wear out FAR faster than the otherwise would. The cost in time and replacements would directly impact every classroom and lead to a worse overall experience for the kids.
