How are you steeping the juice? If it's just in a closed bottle somewhere, the perfumey smell will take forever to go away.
I would recommend you "air out" the bottles every couple of days. For plastic bottles, I just take the cap off, squeeze the bottle to expel the "stale" air and let in fresh a couple of times, then put the cap back on and give it a good shake. The perfume smell won't go away if it has nowhere to go!
Do you have some airspace at the top of the bottle? If it's completely full, try splitting it into 2.
