What you need:
1. Pour baking soda into container, about 1/4 full. Pour in 8ish drops of essential oils.
Well, add a lid if you want. You could nail holes into a mason jar lid but I didn’t want to ruin one. I just covered it with foil and poked some holes. No one will see mine (it’s high up on a shelf) so it didn’t need to have a pretty lid. But make yours as pretty as you want.
Seriously the easiest thing I’ve ever done. Every once in awhile, go shake it so everything mixes and freshens the stinky smells.
