1 tbsp. borax (go to the website to see their research on the safety of using borax)
1 tbsp. grated bar soap (I have been using a natural bar that contains rosemary and lavender)
15-20 drops essential oils (I use around 10 drops of lemon essential oil as my soap already has rosemary and lavender in it. The lemon smells so nice and helps clean the dishes!)
Heat water to boiling.
Combine borax and grated bar soap in a medium bowl. Pour hot water over the mixture. Whisk until the grated soap is completely melted.
Allow mixture to cool on the countertop for 6-8 hours, stirring occasionally. Dish soap will gel upon standing. (Although mine doesn't really gel)
Transfer to a squirt bottle, and add essential oils (if using). Shake well to combine.
Now you’re ready to use your liquid dish soap just as you would use any commercial brand!
