# Clean
## Partial Clean
Even though it is possible to clean up the server without uninstalling the application, it is recommended that the `CleanOpSpec` is implemented for every item.
Imagine one has a goal to test fresh installations of different versions of an application. One approach is to deploy each version in a separate environment, and clean up the whole environment, . have a command that only uninstalls the application from the server, .
Least-work approach, but needs additional engineering.
