Choosing a non-toxic dishwashing liquid is a simple yet impactful way to create a healthier home and support the planet. Many conventional dishwasher detergents contain chemicals that can irritate skin, harm aquatic ecosystems, or leave harmful residues on your dishes. Thankfully, non-toxic dishwasher detergents offer a safer and more eco-friendly alternative. In this guide, we’ll explore what non-toxic means, common toxic ingredients to avoid, and the best non-toxic dishwashing liquids available, detailing their effectiveness, ingredients, and environmental impact.
What Makes a Dishwashing Liquid Non-Toxic?
Non-toxic dishwashing liquids stand out from their conventional counterparts due to their commitment to using plant-based and biodegradable ingredients. These innovative formulas are designed to minimize adverse effects on aquatic environments, setting them apart as environmentally responsible choices. Harnessing the power of biodegradable ingredients, these dishwashing liquids not only efficiently clean dishes but also contribute to reducing overall environmental footprints. Furthermore, these eco-friendly options provide the added benefit of promoting a safer cleaning experience for users, as they are free from harsh synthetic chemicals commonly found in traditional dish soaps.
Key Features of Non-Toxic Dishwashing Liquids
- Plant-Based Surfactants: Derived from natural sources such as coconut, corn, and soy, these surfactants offer numerous benefits: Gentle on Skin: Unlike their synthetic counterparts, plant-based surfactants are typically milder and less likely to cause skin irritation, making them ideal for people with sensitive skin or allergies.
- Environmentally Friendly: These surfactants break down more quickly and completely in the environment, reducing the risk of pollution in waterways and promoting a healthier ecosystem.
- Effective Cleaning Power: Despite being gentle, plant-based surfactants are highly effective at cutting through grease and removing food residues, proving that you don’t need harsh chemicals to get your dishes clean.
- Biodegradable Packaging: Many non-toxic brands use recycled, recyclable, or compostable packaging to minimize waste.
- No Harmful Chemicals: Free from phosphates, synthetic fragrances, dyes, and triclosan, ensuring a safer clean for your dishes.
Top 10 Non-Toxic Dishwashing Liquids
After extensive research and testing, we’ve compiled a list of the top 10 non-toxic dishwashing liquids that deliver sparkling clean dishes while being safe for your family and the environment. Below, we detail each product’s performance, ingredients, benefits, and drawbacks, based on real-world testing and user feedback.
1. Seventh Generation Dish Liquid, Free & Clear
After 65 hours of research, testing 28 detergents and 7 years of long-term testing, we found Seventh Generation Dish Liquid to be the best for most people. Seventh Generation’s Dish Soap is still the best soap for hand-washing dishes. Out of the 28 dishwashing detergents we tested, it has the best combination of cleaning power, safety, price, and social responsibility. You can’t beat the cleaning power of Seventh Generation. Bonus: It’s cheap, it skips the synthetic fragrances, and it isn’t tested on animals. Seventh Generation’s Dish Soap rinses clean from the sponge and cuts through grease better than most soaps we’ve tested. We stick to the unscented version in Wirecutter’s test kitchen, but you can also get it in a variety of plant-derived scents. We’ve tried the clementine zest and lemongrass scent, which was lovely and not overpowering.
- Pros: Plant-based, cruelty-free, affordable, widely available, gentle on skin, no synthetic fragrances or dyes.
- Cons: Runny consistency requires careful dispensing.
- Test Scenario: Tested on greasy silicone baking pans; a small amount created gentle suds that cut through oily residue easily, leaving no scent or food odor.
2. Ecover Zero Dish Soap
Ecover Zero comes recommended to us by Saudia Davis, founder and CEO of GreenHouse Eco-Cleaning, a New York–based cleaning service using all-natural products. Although Davis typically makes a lot of her own household cleaners, she says she gets this biodegradable, fragrance-free dish soap when she buys from a brand. Jen Brady, chief green mama at Green Baby Deals, also says it has an A-rating from the EWG. Brady says it’s gentle on hands but tough on dishes, so she says she feels confident letting her kids use it while dishwashing.
- Pros: Biodegradable, fragrance-free, EWG A-rated, gentle on hands, effective on grease.
- Cons: Slightly pricier than conventional brands.
- Test Scenario: Used on pots and pans with baked-on food; cut through grease with minimal scrubbing, leaving dishes spotless.
3. Mrs. Meyer’s Clean Day Dish Soap, Lemon Verbena
While there’s a lot of great-smelling dish soap out there, Mrs. Meyer’s Clean Day Lemon Verbena Dish Soap is hands-down the best. It smells like real herbs and, well, like clean. It had the unexpected bonus of making my house smell pretty great, too. And my dishes didn’t have any weird, off-putting lingering smells either. (It’s not fun to eat eggs off a plate that smells like flowers!)
- Pros: Pleasant herbal scent, effective on grease, biodegradable ingredients.
- Cons: Scent may be too strong for some users.
- Test Scenario: Tested on glassware and utensils; lush suds lasted through a full sink of dishes, leaving no residue.
4. Etee Liquid Dish Soap Concentrate
I’ve been using this detergent for several months and have been blown away by the results. It cleans just as well as conventional detergents but without leaving any unnecessary chemicals or other unwanted additives behind. Etee makes it onto the list twice…and with good reason…they’re awesome! If you’re looking for a non-toxic liquid dishwashing detergent that works, look no further than Etee. The formula is free from harsh chemicals, toxic additives, and plastic, so it’s completely safe for septic systems and waterways.
- Pros: Plastic-free packaging, biodegradable, septic-safe, powerful cleaning.
- Cons: Requires mixing with water, which may be inconvenient.
- Test Scenario: Applied to greasy cookware; minimal product produced strong suds, cleaning effectively with no residue.
5. Attitude Living Dishwashing Liquid
For cleaning baby bottles, Strategist writer Katherine Gillespie says this vegan and cruelty-free dish cleaner from Attitude Living was specifically developed to remove breast milk and formula (the brand says it will also work well on regular dishes). The soap has the EWG’s highest possible verified rating, which means it’s safe and environmentally friendly, with low-concern ingredients regarding developmental and reproductive toxicity.
- Pros: EWG-verified, vegan, cruelty-free, effective on milk residue, safe for baby bottles.
- Cons: Higher price point.
- Test Scenario: Used on baby bottles with milk film; dissolved residue completely with minimal effort.
6. Dapple Dish Soap
If I had to pick one eco-friendly winner, Dapple was the best. It’s specially formulated to dissolve milk film in baby bottles, and it also works great on grease. Its suds are lush and thick, almost velvety, and they seem to really last. I know that lots of people (Kitchn’s Editor-in-Chief included!) prefer the unscented version, but I have to say: The lavender scent is lovely.
- Pros: Excellent for baby bottles, long-lasting suds, pleasant lavender scent, eco-friendly.
- Cons: Limited scent options.
- Test Scenario: Tested on greasy pots; thick suds maintained cleaning power through multiple items.
7. Rebel Green Dish Soap
When New York features editor Katy Schneider set out to find the next Mrs. Meyer’s a few years ago, she landed on this entirely sulfate-free, biodegradable dish soap from woman-owned company Rebel Green. Schneider says the packaging is charming, the price is low, and the ingredients are even cleaner than Mrs. Meyer’s (the company uses a plant-based formula with natural essential oils).
- Pros: Sulfate-free, biodegradable, affordable, attractive packaging.
- Cons: Less widely available.
- Test Scenario: Used on dinnerware; cleaned grease and food residue effectively with a pleasant scent.
8. 9 Elements Lemon Dishwashing Liquid Soap
If you want an eco-friendly-ish dish soap that cleans as well as the conventional brands, we recommend the lemon-scented 9 Elements Liquid Dish Soap. It should be noted, too, that like conventional dish soaps, the best “eco-friendly” dish soaps contain sodium lauryl sulfate (SLS), a plant-derived surfactant that helps to release messes from surfaces. Consumers often get worked up about the inclusion of SLS in cleaning products, and while it can sometimes irritate sensitive skin, according to a 2015 study, SLS is “readily biodegradable,” and its use in cleaning products “does not introduce unnecessary risk to consumers or the environment.”
- Pros: Comparable to conventional brands, biodegradable SLS, pleasant lemon scent.
- Cons: May irritate sensitive skin.
- Test Scenario: Tested on plastic containers; cut through oily residues with no lingering scent.
9. ECOS Dishmate Dish Liquid
The ECOS brand prides itself on biodegradable ingredients and sustainable manufacturing processes, so it’s no surprise this dishwashing detergent is U.S. EPA Safer Choice Certified. Using coconut-based surfactants, this gentle dish soap created fine suds that cut through grease easily — even on harder-to-wash surfaces like silicone bakeware and plastic food storage containers.
- Pros: EPA Safer Choice Certified, biodegradable, effective on silicone and plastic.
- Cons: Gloppy consistency, underwhelming scent.
- Test Scenario: Applied to silicone bakeware; fine suds cleaned grease without residue.
10. Palmolive Eco Dishwashing Liquid
Two ‘eco’ dishwashing liquids are recommended by our experts, although plenty more only just missed out on being recommended, so are still worth considering. Interestingly, one of these products is from a mainstream brand – Palmolive – yet it spruiks eco claims such as biodegradable cleaning ingredients, recycled bottle, and no parabens, phosphates or phthalates. However, compared to other eco products, this one only has minimal claims. These two eco dishwashing liquids cleaned up in our tests, performing as well as (and often better than) regular products, and earning them a recommendation from our experts.
- Pros: Biodegradable ingredients, recycled bottle, no parabens or phosphates, affordable.
- Cons: Minimal eco claims compared to other brands.
- Test Scenario: Tested on greasy pans; performed comparably to traditional detergents with less scrubbing.
