Marcin,
Under the File menu, turn off "Save Unused Materials". Then when you save the file unused materials will be removed. Be sure to turn it back on so that you do not loose materials in files where you want to keep them all.
Another option would be to select all the objects in your scene and do File > Save Selected.
