I wouldn't but crypto isn't really something you need to worry about unless you are getting a used cage or a new animal that needs to be quarantined. Then just watch for really smelly runny poop in a quarantined animal. In the case of a used cage that you have no idea about the previous occupant, then I would strip the cage down if it can be done and take it outside and clean it thoroughly with ammonia and water, rinse it very well and them let it air dry for a few days.
