Unclog drain mix :) 1/2 c. baking soda, 1/2 c. vinegar. Put down sink cover the drain, wait 15 minutes and pour about 5 C. boiling water down. You might need to use a something long to poke it down inside the drain to help it. Used this today and it worked!!
Mason jar air freshener - fill a small mason jar about 1/4 full with baking soda, and add 6-8 drops of your favorite essential oil. Punch holes in the lid, and place in any spot that could use some freshening. Every once in a while, give the jar a gentle shake to boost it's air freshening power.
