Instead of using an old cleaning tape to try and clean the head and track change sensor of your 8 track player.  I recommend these.  The length makes it fairly easy to get to both with these.  Dip them in some rubbing alcohol (I recomment at least 70%).  And you are ready to clean.  Always unplug your 8 track player before inserting these into it!
