I always thaw and rinse my frozen food with ro water, but doing it everytime I feed is a pita! I thought i seen on one of the foods to only thaw as much as you can use in one day? I guess you shouldn't let it thaw then refreeze, but I'm not sure. I'd like to thaw all my food, rinse it good, mix it up, then put in a icecube tray and refreeze it. Can you do this or once you thaw it you can't refreeze it?
