Deleting Orphaned Moc Files With Make Clean

Is there a way to delete orphaned files during a Make Clean using a .pro file and qtCreator?

I am finding orphaned moc_ and ui_ files after code merges and refactoring. Is there a way to delete these files with qtCreator rather than manually doing it on the command line?

I'm using RHEL 6.x with Qt 4.8.4 and qtCreator 2.7.2.

Thanks

If file names changed in the process of refactoring then deleteing the old object files manually is the only way out.
