I use in the fridge for freshener, sprinkle on carpets and vacuum for an easy deodorizer, mix with water for a scrubbing paste for cleaning the kitchen and bath sinks/tub. I've also sprinkled some in the dishwasher to deodorize it.
Growing up, we used it for teeth brushing. I remember having a jar in the bathroom and sprinkling a bit in my hand and dipping my toothbrush into it.
I should try it for cleaning silver jewelry! Great idea!
Have you seen these uses for baking soda?
