Probably other hives robbed most of the assets, if you have any good comb for restarting a hive, brush off, put in a plastic or paper sack (to reduce mess) and put in freezer for a few days to kill any unwanted occupants. A stiff brush will cleanup woodware, and you'll want to repair or repaint.
If there was a lot of wax moth damage, you can still save the wooden ware. Just clean it up good like mentioned above. Wax moths don't survive freezing temps, so you don't have to worry about them reinfesting your hive if you put new foundation and bees in. Normally a strong hive can limit wax moth infestation during the year. I just chuck the old foundation and start fresh.
