I have tried many different “eco-friendly” dishwasher detergents over the years. From 7th Generation to Ecos, Method to Ecover, I just couldn’t find one that worked very well. And with a price as high as those, I certainly wanted something that worked.
Eventually I came across a recipe to make my own dishwasher detergent. It contained washing soda, borax, salt and citric acid. It worked… somewhat. I wasn’t satisfied with the results and neither was I satisfied with the ingredient Borax. I am not convinced Borax is safe, especially when used on eating utensils etc. After discussing the homemade recipe with some others, the thought came up “what if we just removed the Borax?” So when I ran out of my detergent I did just that. I removed the Borax. I also added white distilled vinegar as a rinse aid. The combination provides great results!!
So here is my borax-free dishwasher detergent recipe:
- 1 cup washing soda (old recipe used baking soda)
- 1/4 c. citric acid
- 1/4 c. coarse salt
- 10-15 drops of citrus essential oil (Optional. Orange, grapefruit, or lemon essential oils have great cleaning as well as antibacterial properties.)
- Distilled white vinegar (in the rinse aid compartment)
Mix first 3 ingredients well in an air tight container. Add essential oil. Mix again. Fill your rinse aid compartment with undiluted white distilled vinegar.
Use 1 tsp. detergent for average loads.
Use 1 tbsp. detergent for extra greasy, dirty loads.
UPDATE: More is not better! If you are having any build up issues use less!
Ingredients used to prepare Borax-Free Dishwasher Detergent:
Citric acid is easily purchased in bulk at U-Brew stores. You may find it at grocery stores near the canning supplies, or in the bulk section. You can also buy it at Mountain Rose Herbs Co. Some people use plain, uncolored koolaid and get the same effects. (Make sure you use the colorless koolaid or you will dye your dishwasher!) This is because koolaid is very high in citric acid. I don’t like the other ingredients in koolaid though so I choose not to use it. Lemi Shine is also sometimes used to replace citric acid. I feel the same way about lemi shine as I do about koolaid.
Coarse salt: same as pickling salt. Found in most grocery stores or purchase coarse sea salt online at Mountain Rose Herbs. Don’t use regular table salt because of the iodine content.
Baking Soda: We all know where to find it!
Essential Oil: Found in most natural food stores or online at Mountain Rose Herbs.
- I rinse off my dishes reasonably well ever since I switched to chemical-free dishwasher detergents. Rinsing off grease and baked-on food will help any cleaner, not just a homemade one.
- Hard water: I don’t know if this would work in hard water or not because my water is soft. However, my own research indicates that citric acid is often used in addition to regular dishwasher detergents to help prevent mineral deposits on the dishes. Try it out and let me know!
- I placed one glass in the dishwasher and left it in for many loads as my tester. I have done over 30 loads with this recipe to date.
Cost: (based on Mountain Rose Herbs prices)
5 lb. of citric acid is $20.
5 lb. of baking soda is $11.75.
5 lb. of coarse sea salt is $15.
Essential oil (optional) varies in price..
Is it worth it to make your own?
Based on the prices above (not including essential oils), and the fact that there are 36 tbsp. of sugar in a lb. (similar texture and weight to this detergent), I worked this detergent out to cost $0.08 a load.
7th Generation dishwashing tabs (about 1 tbsp. each) are $6.99 for 20. (based on online price from London Drugs) So 7th Generation dishwashing tabs cost $0.35 cents a load.
You’ll be saving a lot of money (not to mention your health and the environment) by making your own eco-friendly detergent.
