Want the remove IPTC fields by export

Question

I have a lot of pictures that i will export with a preset.
Because of privacy matters i must remove the IPTC-fields such as sublocation, city, state / province.
Can get that done. To much pictures to remove these fields in Photoshop after the export one by one.....
Naturally i want to keep this info in the field in my originals !

Hi John, I have installed the metadata wrangler but no luck....
Maybe it has something to do with the fact that some of the pictures were originally imported with PhotoMechanic.
Thanks for your answer !
Piet Van de Eynde (the writer of excellent LR-books) came up with a answer that looks interesting, i will try that one ! but it is not for daily use on a speedy workflow...
Save locations
For photos captured within a defined proximity, you can create a saved location. For example, if you travel to Greece for a photo shoot for a client, you can create a saved location that encompasses the islands you visited.
In the Map module, navigate to a location on the map and click the + button in the Saved Locations panel. The Saved Location panel is on the left side of the Lightroom window. 
In the New Location dialog box, enter a name for the location and select a folder to save it in. 
Radius
Defines a radius, in feet, miles, meters, or kilometers, from the center of the visible map area.
Private
Removes all IPTC location metadata, including GPS coordinates, Sublocation, City, State/Province, Country, and ISO Country Code, when photos in the saved location are exported from Lightroom.
Click Create.The location appears on the map marked by a white circle, with one pin in the center and another pin on the perimeter. 
When working with saved locations, do any of the following: 
Select or deselect a location in the Saved Locations panel to view it on the map.

To add photos to the location, do one of the following:
Drag one or more photos from the Filmstrip into the white circle in the map.
Select one or more photos in the Filmstrip and select the check box next to the location name in the Saved Locations panel.
To go to a location on the map, click the right-arrow button by the location name in Saved Locations panel.
To edit a location, right-click (Windows) or Control-click (Mac OS) it in the Saved Locations panel and choose Location Options.Tip: You can also drag the pin at the top of the location circle in the map to adjust the radius. Drag the pin in the center of the circle to move the location on the map.
To remove a location, select it in the Saved Locations panel and click the minus ( - ) button. Or, right-click (Windows) or Control-click (Mac OS) it in the Saved Locations panel or on the map and choose Delete.
