But this DIY combo actually works. The natural detergent and rinse aid work together beautifully, leaving your dishes clean, clear, and chemical-free. You won’t miss what you used to use.

Ingredients for Natural Dishwasher Detergent

Washing Soda

Washing soda, also known as sodium carbonate or soda ash, is a powerful, natural cleaning agent and a key ingredient in homemade dishwasher detergent. You can easily make it at home by baking baking soda at 400°F for about 30 minutes, which transforms it into a more alkaline form.

Its high alkalinity helps break down stubborn grease, dried-on food, and tough stains on dishes. It also neutralizes odours and softens hard water, allowing your detergent to clean more effectively. In the dishwasher, washing soda boosts the cleaning power of other ingredients and helps prevent cloudy glassware caused by mineral buildup—leaving your dishes sparkling clean, naturally.

Borax

Borax, also known as sodium borate, is a naturally occurring mineral that’s incredibly effective in homemade cleaning products—including dishwasher detergent. In the dishwasher, borax works as a cleaning booster, helping to cut through grease, break down stuck-on food, and lift tough stains from dishes.

Its mild antibacterial and antifungal properties also help reduce germs and odours, leaving dishes smelling fresh without synthetic fragrances. As an alkaline compound and water softener, borax improves the performance of other cleaning ingredients by allowing them to work more efficiently—especially in hard water. It also helps prevent mineral buildup on glassware and dishes, so you’re left with a clear, sparkling finish every time.

Salt

In homemade dishwasher detergent, salt acts as a gentle abrasive to help scrub off food particles and residue. More importantly, it works as a water softener—binding to minerals in hard water so they don’t leave spots or film on your dishes.

By softening the water, salt boosts the effectiveness of your detergent, allowing other ingredients to clean more thoroughly. It also helps prevent limescale and mineral deposits from building up in your dishwasher over time, extending the life of your machine and keeping your glassware crystal clear.

Citric Acid

Citric acid is a natural, plant-derived acid commonly found in citrus fruits. In homemade dishwasher detergent, it’s a powerful multipurpose ingredient that tackles several common dishwashing issues at once. It helps to break down hard water deposits, eliminate soap scum, and prevent the white film or cloudy appearance often left behind on glassware.

Thanks to its mild acidic nature, citric acid also works as a natural preservative and deodorizer, leaving your dishwasher and dishes smelling fresh without synthetic fragrances. It enhances the overall effectiveness of your detergent by balancing the pH and dissolving mineral buildup, helping your dishes come out sparkling clean.

Homemade Natural Rinse Aid

You’ve probably heard that straight up white vinegar is a great natural rinse aid. Take that to a next level and reduce waste by infusing white vinegar with leftover citrus rinds.

White Vinegar

White vinegar is a simple, affordable, and effective natural rinse aid for your dishwasher. Its mild acidity helps break down hard water minerals and prevent spots or streaks from forming on glassware, cutlery, and dishes.

White vinegar also acts as a natural deodorizer and rinse booster, keeping both your dishes and dishwasher fresh without synthetic fragrances or unnecessary additives. It’s especially helpful if you live in a hard water area and want to improve your dishwasher’s performance without spending extra on specialty products.

Citrus Juice

Citrus-infused white vinegar takes natural rinse aid to the next level. While white vinegar alone helps prevent water spots and mineral buildup, infusing it with citrus peels—like lemon, orange, or grapefruit—adds extra cleaning power and a subtle, fresh scent.

The natural oils in citrus peels act as a powerful degreaser and antibacterial compound that helps cut through any lingering film or residue on dishes. The citrus also adds a bright, pleasant aroma that softens the sharp vinegar smell without synthetic fragrance.
