If you’ve already upgraded your sponge and swapped out harsh cleaners, your dish soap is the next step in building a healthier kitchen. Conventional dish soaps—even the “green” ones—often contain synthetic fragrances, artificial colors, preservatives, and surfactants that can strip your skin and leave chemical residues on your plates.
This week’s DIY is a simple but powerful non-toxic dish soap made from just a few plant-based ingredients. It cuts through grease, rinses clean, and won’t damage your natural scrubber or dry out your hands. Plus, you can customize it with essential oils you love (or keep it scent-free if your skin is sensitive).
Ingredients (for a 16 oz bottle):
- 1/2 cup liquid castile soap (unscented or mild-scented like citrus or tea tree)
- 1 tablespoon baking soda (mild abrasive + helps degrease)
- 1 tablespoon vegetable glycerin (adds moisture + softens hands)
- 1 tablespoon white vinegar (cuts grease + balances pH)
- 10–15 drops essential oil (optional: lemon, eucalyptus, orange, tea tree, or lavender)
- 1.5 cups warm filtered water
- A glass bottle
Why these ingredients work:
Castile soap is a plant-based soap concentrate that’s gentle, biodegradable, and effective.
Baking soda helps lift grease and food residue.
Vegetable glycerin keeps your hands from drying out—especially important if you’re hand-washing a lot.
Vinegar improves grease-cutting power but is used in small enough amounts to avoid clashing with the soap.
Essential oils add natural antibacterial benefits and a refreshing, non-toxic scent.
Instructions:
- Combine the baking soda, vinegar, and water in a mixing bowl or large measuring cup. Stir gently (it may fizz slightly).
- Add the castile soap and glycerin, and stir slowly to combine.
- Add your essential oils, if using.
- Pour the mixture carefully into your clean soap dispenser or pump bottle. Shake gently before each use.
How to use it:
- A little goes a long way! Squirt a small amount directly onto your dish brush or loofah sponge.
- For extra tough pans, sprinkle some baking soda on the surface before scrubbing.
- For soaking dishes, add a squirt of hot water in the sink or basin.
Storage + shelf life:
Store your DIY dish soap in a cool, dry place away from direct sunlight. It should stay fresh for 1–2 months. If you notice any separation, shake the bottle—this is normal for handmade products without synthetic stabilizers.
What it doesn’t contain:
- No sulfates
- No triclosan
- No synthetic fragrances or dyes
- No preservatives or alcohols
- No mystery “fragrance” blend
This simple swap is a game-changer. You’ll be able to know exactly what’s going onto your dishes (and into your hands), and you’ll be keeping toxic residues out of your home—and your ecosystem. Paired with your new non-toxic sponge and cleaner, you’ll build a kitchen routine aligned with your values: low-waste, low-tox, and suitable for everyone who eats off those plates.
