Start with adding 1 tablespoon of baking soda to a clean spray bottle. You can buy these for $1 at The Dollar Tree or clean out an old spray bottle thoroughly and recycle it. Later add two cups of warm water and put the lid on and shake until the baking soda has dissolved.
Take the lid off and add 10 drops of lavendar essential oil. The smell of lavendar is great and use a different scent, like maybe lemon if you want to. The next step is to put the lid back on and shake well.
There you go, you made yourself a fabric refresher spray in few minutes.
