I actually don't recall any point in time in the anime that they have. 

They all just seem to leave it there.

I could be wrong though. Lots of episodes. Been awhile. XD

I don't even think they get left there in most cases. I know for sure after Grey bests the hat wearing dude, his ice is still there, but not the actual items made during the battle.
