I wipe them off and toss them in the storage. Before using them I will sterilize them by putting the ends in the fire, then wipe them down with a wet cloth and go to cooking. Not sure if you will find a tupperware container that big but I guess you could use a fish pole tube or a plastic/PVC shipping tube with end caps if you have to keep them contained.
