You may try [Features Cleanup sandbox module][1] as add-on to Features which can do cleanup of fields, vocabularies, panel nodes, mini panels, and image styles that are in the database, but not in any enabled features module.

This is potentially dangerous module, since it can irrevertibly delete database components once they got removed from the Features, so you should test it first if that meets your expectations and it has been tested with your deployment plan and scripts.

This module is separated into two different tasks:

- Resolve Overrides

  You will have new option *Resolve All Overrides* at the bottom of Feature's overview screen which will attempt to cleanup all overrides by deleting existing database components (mainly fields). After that, it will revert this feature.

- Delete existing components that are not in any Features modules

  This includes: content types, mini panels, node panels, taxonomy vocabularies, image styles, etc.

  Before doing it, you need to enable all features that you want to compare against. Then click on *Features Cleanup* in the Features listing screen.

This module also has drush integration:

- `features-cleanup`

  Run the cleanup task and run features-revert-all afterwards.

- `drush features-resolve-override [feature name] [component list]`

  Resolves overrides for features modules. This will run features-revert on the given feature.
