I am wanting to empty out some old canned goods (homemade) like peas, salsa, dill pickles and make room for this years crop, plus I can reuse the jars. Can they be put into the compost bin? I'm still somewhat new to composting and don't want to mess up my compost I've got going. If so on the vinegar base items should I drain the vinegar out first? TIA, trudyjean
