Natural Scouring Powder

This is a 2 part recipe:

First, purchase two boxes of Baking Soda. Put one into various containers in the fridge and freezer to eliminate odors. After about 30 days, find an empty container to dump OLD baking soda into. Using second box, refill various containers for fridge.

Now, you can use the old baking soda as scouring powder! You can add Tea Tree or Lemon Essential oil to the soda to add scent and germ killing power.
My personal fave is Tea Tree!
