I live in a smaller home, and finding room for food storage is difficult. I need a place to store my dry goods like pastas, beans, rice, and oats. I have a detached garage that is NOT air conditioned, and a couple of old refrigerators that no longer work. I know that fridges are somewhat air tight but, would I be ok to use these old refrigerators in my garage to store these shorter term food items, that I'll be rotating out periodically, and replenishing them as they are used. Thanks a bunch.
