Here’s how to make your own detergent pods:
Grate a bar of pure soap (such as Ivory) until you have 1/2 cup grated soap. In a glass mixing bowl, combine the grated soap, 1 1/2 cups washing soda, and 2 tablespoons Epsom salts. Mix in 3 tablespoons 3 percent hydrogen peroxide and 1/4 cup vinegar. Scoop the mixture by heaping tablespoons onto a baking sheet lined with wax or parchment paper.
You should have enough for 24.
Give the piles-to-become-pods a little spritz of water to set, and allow to dry (about 12 hours). Once dry, store the pods in an airtight container. Like your laundry to smell fresh? You can add 10 to 20 drops of your favorite essential oil when you add the peroxide and vinegar.
