#Garbage Collector
* everything auto draft
* items from deleted collections
There is a first, experimental version of a WP CLI command for that:
```
wp tainacan garbage-collector
```
For more info:
```
wp help tainacan garbage-collector
```
It will clean:
* items from deleted collections (and its comments and metadata)
* documents and attachments from deleted items
* deleted metadata (currently there is interface to untrash them)
* post_meta of deleted metadata
* post_meta of deleted instaces of a multiple compound Metadatum. post_meta of a metadatum that is child of a compound metadatum, but which the ID does not appear in any array of a compound metadatum meta_value
* orphan terms (with taxonomy that does not exist)
* tnc_bulk postmeta
* tnc_bulk postmeta (temporary metadata used to group items for bulk edit operations)
