deleted objects still in scene I have a couple of objects in scene that were deleted and they still show up in blender file and data blocks view and their materials aswell and I cannot select them and I cannot unlink them and make local does nothing...

How I remove these unused objects and their materials?
The question is a bit sparse on information so this is a bit of a shot in the dark. 

In your outliner panel where it says All Scenes, select Orphan Data, if the data which should be gone is visible there you can press Purge All to remove the data from the scene. 

Best Regards
