Contact cleaner
Contact cleaner deletes the Contact fields stored in your Medallia Experience Cloud instance. Use Contact cleaner to deselect Used for contact identity property in a Contact field to redefine which Contact field(s) you want to use as contact identity to a build a Profile. For more information, see Profile field settings.
Click Start to run a Contact cleaner. When completed, Experience Cloud grants 48 hours to deselect Used for contact identity in the Contact field(s) that have it and to select it in the Contact field(s) that do not have it selected. After 48 hours, you must run the Contact cleaner again to deselect Used for contact identity.

When to use Contact cleaner
Contact cleaner was implemented to resolve erroneously merged contact profiles.
When configuring Profiles, fields which can contain non-unique values are occasionally marked as identity fields. For example, if the age field has the Used for contact identity property selected, all contacts with the same value for age are merged to the same contact profile, which is clearly incorrect.
Once merged, contacts cannot be un-merged without using Contact cleaner, which includes the removal and reprocessing of all contacts. Contact cleaner resolves the erroneous merge by enabling the user to redefine which fields have the Used for contact identity property, removing all contacts, and running a backfill to re-extract all contacts with the revised field properties.
