3 Homemade Dishwasher Detergent Recipes To DIY Your Dirty Dishes
By using simple, natural ingredients, you can create a homemade dishwasher detergent that cleans just as well as store-bought options without harsh chemicals or unnecessary waste.
Especially since many conventional dishwasher detergents contain ingredients like phosphates, chlorine, and polyvinyl alcohol (PVA), which can harm aquatic ecosystems and contribute to plastic pollution. We know they’re convenient, but is that worth their hidden environmental costs?
Unless you’re buying a non-toxic dishwasher detergent from selected brands, we don’t think so!
So to help you navigate the world of DIY dish detergents, we’re sharing 3 of our favorite go-to recipes we’ve been using for years. Specifically dishwashing detergent powder, liquid and pods (or tablets). These all strike a balance between performance (they’re super effective and you can tweak the ratios depending on your preference), sustainability and cost saving.
Whether you’re looking to reduce your household’s reliance on single-use plastics or avoid harmful additives, these recipes are a step toward greener cleaning—and you don’t even need to sink (pun intended) a lot of time into making them.
1. Homemade Dishwasher Detergent Powder
This simple DIY dish detergent powder is a cost-effective (but not as much as the tablets), low-waste option that’s perfect for everyday dishwashing. I use this recipe the most just because it’s the easiest out of the three to make.
This recipe makes enough for approximately 12 loads (or 6 very large, heavy soiled loads) but is also extremely easy to double or even quadruple if you want to make more at a time, as it’s shelf-stable.
Ingredients:
- 1/4 cup washing soda: Breaks down grease and grime. Note this is not the same thing as baking soda; it actually has more grease-fighting power. We suggest buying it in a cardboard box, like from Arm & Hammer.
- 1/4 cup baking soda: Adds a gentle abrasive for spotless cleaning.
- 2 tbsp. citric acid: Boosts cleaning power and helps prevent water spots.
- 2 tbsp. kosher salt: Softens water and aids in scrubbing. Note that Kosher or dishwasher salt is recommended as the grains of both are coarser, which will prevent any clogging of your dishwasher.
Recipe:
- Combine all ingredients in a bowl (can it get any more simple than that!?). Mix thoroughly to break up any clumps.
- Store the powder in an airtight container.
- Use 1-2 tablespoons per dishwasher load.
2.Homemade Dishwasher Detergent Liquid
If you prefer a liquid detergent, this recipe is both effective and easy to mix. Though it costs the most to make out of all three options it does tend to have the best scent if you add the essential oil.
Ingredients:
- 1/2 cup castile soap: Cleans dishes gently but effectively.
- 1/4 cup white vinegar: Cuts through grease and removes water spots.
- 2 tbsp. lemon juice: Adds natural antibacterial properties and a fresh scent.
- 2 tbsp. cup water: Dilutes the mixture for easier use.
- 5 drops of essential oil (optional): If you’re interested in adding fragrance to this DIY dishwasher detergent liquid, we find lemon is a great addition for grease-cutting and complements the natural lemon juice in the recipe.
- Recipe:
- Combine all ingredients in a jar or bottle. Stir or shake well to combine. It should result in a thick, paste-like consistency.
- Store in a sealed container; a wide mouth jar works best as the thick consistency means you’ll need to scoop rather than pour the liquid.
- Shake before each use and use 1-2 tablespoons per dishwasher load.
3.Homemade Dishwasher Detergent Tablets
DIY Dishwasher pods are the most convenient to use for busy households. They’re not the easiest to make in this list but because you don’t need to measure out detergent every time you need to wash the dishes, they may end up saving you more time in the long run.
These are also much more environmentally friendly compared to most commercial pods which contain harmful ingredients, most notably polyvinyl alcohol (PVA), which is a plastic-like substance used to bind the pod together and dissolve in the wash. While PVA is designed to break down in water, it often doesn’t fully degrade in wastewater treatment facilities, contributing to microplastic pollution that can end up in our oceans and harm marine life.
By opting for truly plastic-free homemade dishwasher detergent cubes, you eliminate the need for PVA altogether, opting instead for ingredients that are biodegradable and environmentally friendly.
Ingredients:
- 1/3 cup lemon juice or white vinegar: Acts as a natural rinse aid and binds the mixture.
- ⅓ cup kosher salt: Softens water for better cleaning and helps reduce hard water stains and residue.
- ⅓ cup of baking soda: Aids in scrubbing and deodorizing.
- ⅓ cup of washing soda: Provides powerful grease-fighting action.
- 5-10 drops of essential oil (optional): If you’re interested in adding fragrance to these DIY dishwasher detergent tablets, we recommend lemon or tea tree oils for their grease-cutting and antibacterial properties.
- Silicone ice cube tray: We like using the mini ice cube trays because especially for our half-size dishwasher, a large cube is just too excessive.
Recipe:
- In a mixing bowl, combine the washing soda, baking soda, and salt. Stir to break up clumps.
- Slowly add the lemon juice or vinegar, noting that some fizzing is normal. Mix until the liquid is fully absorbed by the dry ingredients.
- Add essential oil if desired and stir again.
- Press the mixture firmly into a silicone ice cube tray, tamping down to eliminate air pockets.
- Leave the tray on the counter to dry for at least 12 hours or until the pods are completely hardened.
- Pop the pods out of the mold and store them in an airtight container. Use one pod per dishwasher load.
