Update, March 2018: When I first started making these, I used ice cube trays and filled them about halfway. While that worked okay, I’ve since found some awesome silicone molds that are much easier! They are the perfect size, and the finished tabs pop out easily. No more fighting with the ice cube tray! Using the below recipe, you’ll yield approximately 50 of the tabs in the silicone mold.

Original Post: Wow! These were easy to make, and they work! Scrap those expensive dishwasher detergent tabs, and make your own!
- 3/4 cups washing soda (find it by the laundry stain & odor removers)
- 3/4 cups Borax (find it by the laundry stain & odor removers)
- 1/2 cup coarse kosher salt
- 1/4 cup citric acid (find it in the canning aisle)
- 1/4 cup white distilled vinegar
- 30 drops lemon essential oil
- Mix dry ingredients and essential oils in a large plastic bowl, using a wooden or silicone spoon. Do NOT use a metal bowl or a metal spoon.
- Slowly stir in vinegar in small amounts. If you add the vinegar too quickly, the citric acid will bubble like crazy, and you’ll never get it to settle down. Trust me–learned that the hard way!
- Press into molds. I found it was easiest to do this with my fingers. Pack down slightly; some expansion is normal.
- Allow to dry at room temperature. In a dry environment, they’ll be ready to pop out in 6-8 hours. In more humid environments, you may need to wait 24 or more hours.
- Pop out of molds and transfer to an airtight container to store. Store in a cool, dark place.
- Yield: approx. 50 tabs (in the mold referenced above)
- Tabs don’t have to be placed in the detergent compartment. If your dishwasher has a special location for tabs, use that. Otherwise, you can just toss one on the bottom of the tub.
- For rinse agent, I use distilled white vinegar with lemon essential oil–20 drops oil per quart of vinegar. Shake before filling compartment.
- These tabs are also multi-purpose!
- Drop one in your garbage disposal, run hot water, and let the disposal run for 30 seconds to a minute.
- Toss one on the bottom of your dishwasher tub, and run an empty hot cycle with sanitize (if your dishwasher has that option) to clean your dishwasher tub and lines.
- Have an extra-greasy load? Hard water? If you answered yes to either (or both!) of those things, add just a couple (no more than three) drops of regular dish soap to your dishwasher when you run a load.
- This recipe = 5 cents per load
- Finish tabs at Walmart = 17 cents per load
