Purge deleted Stacks

We have a workload that uses a CloudFormation Stack to create Amazon Connect Quick Connects. The Stack has a fixed name: "AddressBook". When the workload starts (about once per week), any existing AddressBook stack is deleted and a new AddressBook Stack created from a fresh template. That all works good but we now have many instances of the AddressBook Stack with a DELETE_COMPLETE Status. It seems a waste of resources to leave these deleted Stacks lying around. How do you get rid of them, or am I worrying unnecessarily?
