Bedding for Chinchilla Cage

Hi, I was planning on getting a Chinchilla soon and I was wondering what type of bedding you should use if a cage has wire bottoms. I’m not sure how well you could put aspen shavings on top of the wire (and if that would help at all).

A lot of people I’ve seen have recommended fleece bedding, but I’m not really sure about the cleaning of it and how much it would cost to upkeep it. Is someone able to explain that for me? Thanks!
