Can't remove unwanted quest items from inventory [FIXED, IGNORE]

Hi, is there any way I can remove quest items from my inventory? Accidentally went and picked up a Decanter in normal and now I've picked up Chitus' plum in cruel.

I don't want to do the quests and I can't even put them in my inventory.

Wouldn't be an issue except the quest rewards are crap and I want my inventory space back.

Thanks.

Just drop them in a zone (not in town).

OMG. How did I not try that? Thanks for the help bud.
