How do marsupials clean their pouches? Do they smell terrible?

I was thinking about how disgusting a human pouch would be. Can someone elaborate?

Much like grooming other parts of the body, they lick them clean. The frequency of pouch grooming has been observed to increase when the joeys are in the pouch.
