I was browsing Pinterest and Facebook a while back, and saw a couple ideas for some dishwasher cubes. They looked easy enough to make, and when I did a search online, there were a few different recipes for homemade dishwasher soap, but I modified a couple and this is what I came up with.
Tools you’ll need:
A mixing bowl
3 Ice Cube Trays
A sunny day or warm windowsill
2 cups Borax Laundry Booster (found in the laundry aisle)
2 cups Arm & Hammer Super Washing Soda (I got mine at my Kroger- in the laundry aisle- Alternately, I learned that you can make your own by heating regular baking soda at 400 degrees in the oven for about an hour)
1/2 cup Epsom Salt
1/2 cup Lemon Juice
5 drops either Lavender or Tea Tree Essential Oil (Optional- but to make it easier, add it to the lemon juice)
Mix all the dry ingredients together well, then add your lemon juice/EO mixture. Because of the reaction with the Epsom salts, it may fizz a bit, but just start mixing and keep mixing till all your dry ingredients are dampened with the lemon juice mixture. You’ll have a “wet sand” type consistency.
Pull out your trays and spoon/spatula the mixture into the ice cube trays, pressing each compartment down with the back of the spoon to compact the “sand” mixture into the ice cube tray. This mixture should fill 3 ice cube trays (I bought a set of 3 at Walmart for 1.13).
Set the trays in a sunny windowsill or outside to dry in the sun for a couple of hours. You could leave them on the sill overnight. When they’re dry, gently un-mold the cubes and store in a plastic storage container or plastic bag.
Pop them into the compartment for your dishwasher and VOILA! I’ve added vinegar where the “jet dry”/rinse aid section is for my dishwasher as well. These work just as well, if not better than most of the store bought dishwashing detergents and because of the essential oils, there’s the added benefit of a pleasant naturally antibacterial fragrance.
