Don't eat at KFC so I don't have any of their containers. I do save Classico spaghetti sauce jars. First thing I do is soak off the label and put jar into dishwasher, after cleaning the cap I pour a little bleach into it and let it set about 15 minutes, rinse it thoroughly and put it into dishwasher. I use these jars to hold small amounts of macaroni, sugar, flour, home made salad dressing, etc. I also use them to put up come apple butter.
