Real Simple magazine has their monthly feature entitled "time saving new uses for old things". One of this months features was a very surprising tip with lemonade Kool-Aid. According to Real Simple, the lemonade's citric acid [the only flavor BTW] cleans lime deposits and iron stain inside the dishwasher. We once heard KCRW's Good Food host Evan Kleiman report back on the recommend of putting a dirty sponge in with the dishwasher cycle to get rid of bacteria, and when one homeowner tried it in her brand new high-tech, fancy dishwasher... things went horribly wrong. Has anyone tried this Kool-Aid trick? Did you notice a difference? Or do your dishes have a lemon essense these days?
