Some people are not keen at their stuff going in with ours..but to be honest if your washing at a 60c and using a wash bag which saves the hay washing machine from bits of hay or using a antibacterial pet bed wash like me and my OH then it kills all germs anyway but it is personal opinionI would use fleece, but the problem would be whether or not my mum would be too happy with it going in her washing machine. This is why I was looking for disposable stuff hehe
I used eco pet bed for the rats after binning carefresh and it worked well. good value for money too and lasted at least 6 months with a 20kg sack the bits were quite big though and I personally wouldnt use it for my piggies as it can be rough but i think it depends where you but it from. Smaller finer bits would be fine.Have a look at fitch or finacard (also ecopetbed, green mile etc.). I'd agree that carefresh is very expensive and not very good, some people think it's dusty/irritating.
