Have you tried placing the affected supers above the inner cover.  The bees
will clean out the granulated honey, carrying it down to brood chamber for
winter stores.  This gets the "set" honey out of your supers, gives the bees
winter stores, and eliminates all stickiness from those supers as the bees
do such a good job of removing every last drop of honey.  It only takes them
a very short time - 2 or 3 days is sufficient with reasonably warm days.
 
Good Luck!
