The Most-Eco Friendly Dish Soaps, Dish Washing Soaps and Washing Up Liquids That Actually Work
The last thing you want to do when washing the dishes is to hurt your skin. Yet many dish soaps do exactly this. They’re made up of harsh detergents and irritating add-ins like fragrance which firstly – are eating away at your skin barrier and secondly – are allowing in potentially harmful allergens.
How do you do better?
How do you choose a dish soap which is kind to you plus kind to the environment?
Fact; dish soaps work because they mix together oil and water. It sounds simple – but in nature, there aren’t many ingredients that can do this.
Strong detergents eat away a lot of oil i.e. grease build-up. However, your skin’s top layers are also oil-based – and so good for the dishes can mean harmful for your body health.
Instead of relying on harsh detergent actives, there are clever workarounds. The chemistry of combining mild detergents to create a dish soap which has – in science terms – synergistic power. Meaning 1 + 1, no longer equals 2, instead, it equals the power of 4 (!)
If you’re looking for a bottle of carefully formulated dish soap, one which is kind to your body, safe as can be, while also packing a punch to your burnt-on food stains, you’re in the right place. After reviewing hundreds of cleaning products, and putting our favorite dish soaps to the test, you’re about to discover 5 best dish soaps which fit this brief perfectly.
They’ll be no turning back once you discover our winning 5;
What’s in this article:
The Winner – Aspen Dish Soap
Smells great, looks great, cleans great. Aspen Natural Dish Soap goes above and beyond. Made by a Canadian based company that are EcoCert approved, EWG ranked and certified by the leaping bunny. There are accreditations galore.
The first ingredient on Aspen’s list is… salt (!) or sodium chloride to be specific. Salt is used in detergent products to impact the thinness/thickness of a formula, to increase/boost foaming and to improve what scientists call ‘wetting properties’.
Here comes that extra important, synergistic science.
Wetting properties refer to how well a liquid can dissolve in water and how well it can lower the surface tension between liquid and solid.
These are both especially important properties as when both are maximized – cleaning performance is excellent.
The actual detergents used in this formula – lauryl glucoside and coco glucoside are both known as mild and sensitive skin-friendly. In fact, a common aka cheap but not so skin-friendly detergent called Sodium Laureth Sulfate (SLES) may be improved in mildness by addition of lauryl glucoside.
Overall an excellent formula, with excellent cleaning performance – dishes look and smell fantastic.

|A combination of salt and gentle surfactants makes Aspen Dish Soap a gentle yet extremely effective dish soap that is kind to you, your environment and your wallet.|
2nd Place – Biokleen Free & Clear Dish Liquid
Biodegradable, extremely affordable, cruelty-free, plant-based and exceptionally effective at cleaning. Biokleen Free & Clear Dish Liquid is a clear stand out in washing performance – it can even tackle burnt on tray cheese plus microwaved, made in a mug brownie cake.
Biokleen Free & Clear Dish Liquid uses a combination of 5 detergents. To put that into context our 1st place winner uses 2. A combination of detergents can mean;
- More effective cleaning power – due to detergents having different cleaning capabilities
- Use of strong detergents can be made less irritating to skin
And that #2 is what’s happening here. Biokleen Free & Clear Dish Liquid in fact uses one of those strong, yet usually irritating detergents we just spoke about – Sodium Lauryl Sulfate (SLS).
Take a read of this quote from a paper published in the Journal of Surfactants and Detergents in 2015, this quote refers to the combination of a mild/low skin irritation detergent i.e. cocobetaine/ cocamidopropyl betaine being paired with a stronger/high skin irritation detergent i.e. SLS;
“This combination is designed to change the surface properties. An example of such a combination is a mixture of cocobetaine and sodium lauryl sulfate (SLS) as the primary surfactant, which reduces the irritation of the skin and mucous membranes, strengthens the feeling on the skin, and increases the organoleptic sensations” 
Bottom line; Biokleen make clever use of this science. They use SLS for ultimate cleaning performance, and yet they also use a higher amount of cocamidopropyl betaine to reduce skin irritation.
This is science in action.
For cleaning power as good as you’ve ever seen – choose Biokleen Free & Clear Dish Liquid.

How We Chose The Winners
Here at Safe Household Cleaning – we do things differently.
We’ve spent literally hundreds of hours reviewing and assessing cleaning products. Every single one of the dish soaps reviewed on this site has been expertly tested and thoroughly researched.
In addition, we have certain criteria that must be met before we’ll put do these reviews. For example, we won’t review a dish soap if the manufacturer won’t disclose the ingredients. And there are still far too many who don’t. With these ingredients in mind, we use pharmacists, product formulators and dermatologists to assess the overall formulation of the product. While in use performance is paramount – many dish soaps can have fantastic cleaning performance with the sizeable compromise of poor skin safety plus poor environmental impact.
Our findings are based on science – you can’t argue with that.
At Safe Household Cleaning, we are cutting through this fog. As you’re here reading this with us now, we’re sure you already understand ingredients are just as important as how well a dish soap works.
We open the science lid on ingredient safety.
The Best Dish Soaps and Washing Up Liquids
While we love every one of our winners, there’s far more choice available should you wish to look for an alternative.
Here are the best non-toxic, gentlest, All-Purpose Cleaners on the market today
AspenClean Natural Dish Soap Eucalyptus & Rosemary
Quite outstanding. This dish soap smells great, washes great and has a low irritation potential for all but the most sensitive of skin. The ingredients are plant based, cruelty free and the bottle is 100% recycled and recyclable. There's so much to like with this company and this dish soap, and we can't recommend it highly enough.
Biokleen Free and Clear Dish Liquid
This product does not disappoint.
As well as being a very affordable product, it's biodegradable, cruelty-free, plant-based and extremely good at cleaning.
It does contain SLS and Cocamidopropyl Betaine, but so does your shampoo! And the trade-off for having two harsh ingredients in there is a cleaning power as good as I've seen.
The Honest Company Baby Dish Soap
Excellent for doing what it was designed to do: clean baby items. It's not a suitable replacement for your regular dish soap - it's simply too gentle.<.p>
If you want to use all baby products in a gentle no-fuss formula, then this is an excellent option.
Just don't try it on your pots and pans and expect good results.
The Honest Co. Dish Soap
Almost perfect. It washes well, relatively safe to use in the home and safe to use in the home, and minimal impact on the environment compared to its non-eco friendly competitors. If it was slightly more concentrated we'd be looking at a 5 star review.
Attitude Natural Dishwashing Liquid
It's plant-derived. Biodegradable. The ingredients are gentle. It washes well.
All things considered, I'd definitely recommend it. Especially for those with sensitive skin!
Puracy Natural Dish Soap
It looks great, smells amazing and washes as well as any dish soap I've used in my life. 99% of this formula is plant-based, gentle and biodegradable. So why Puracy have added a harsh synthetic preservative like Benzisothiazolinone is almost bizarre.
If you're sensitive to fragrances, wear gloves. If you're sensitive to any of the Thiazoles, I would stay well clear.
With a tweak here and there to the formulation, this could have been a 5 star review. As it is, they must try harder!
Seventh Generation Natural Dish Liquid
I can't question the ability of this product to wash your dishes. I also can't question the credentials of the company that make it. 95% of this product is outstanding, but the other 5%, the preservatives, can cause such extreme reactions in sufferers, I can't wholeheartedly recommend this product.
Which is such a shame. A couple of minor tweaks ie replace the preservatives, and this would be world class.
Mrs Meyers Clean Day Dish Soap
Overall, Mrs. Meyer's Clean Day Dish Soap smells absolutely amazing and cleans very well too.
Unfortunately, there are one or two ingredients in there you should be aware of before buying.
If you are prone to contact dermatitis, anything from the cleansing agents to the essential oils to the preservatives could be a trigger for you. Meyers may be an alright option for the Average Joe, but if you have skin sensitivities, you might want to keep looking.
If you are dying for some good aromatherapy, use at your own risk and be sure to glove up.
GrabGreen Fragrance Free Dish Soap
We have used products that clean better. And we have reviewed products with ingredients that are gentler on you and the environment. While the company must be applauded or being this transparent with the contents of the dish soap, we really hope their next formulation shows a little more imagination with the cleaning agents and preservatives.
It's a decent dish soap, a step up from the usual supermarket bought brands, but we have tried better.
Method Dish Soap Lime and Sea Salt
This product cleans well and it smells great. It's made with cruelty free ingredients, and does use naturally derived ingredients, but there are a number of issues, particularly for sensitive skin sufferers. The fragrances and preservatives are known allergens and if you are of a sensitive disposition, you may want to look elsewhere.
J.R. Watkins Dish Soap
J.R. Watkins dish soap is manufactured by a reputable transparent company. It does a good job of cleaning dishes. And we know what ingredients are in the bottle. In addition, Watkins bottles are partially recycled from used consumer products, and they don't test on animals. Not to mention, their branding is pretty cool.
Unfortunately, there's too many fairly harsh ingredients for our liking. I hoped manufacturers would have ceased using methylisothiazolinone altogether by now. It also contains sulfates, phenoxyethanol and a number of other ingredients that could induce contact dermatitis.
If you do decide to use it - be sure to wear gloves!
What To Look For In Dish Soap
How do you know if a dish soap is kind to the skin? How do you know if a dish soap is safe to use? How do you know if a dish soap will work?
While there are an infinite amount of dish soap ingredients to choose from, the #1 ingredient which makes most difference to all 3 of these questions is the detergent selection aka the surfactants.
Take a look at this list below. It’s a summary of all detergents used in the 5 best dish soaps we’ve reviewed here;
- Lauryl Glucoside – non-ionic, mild detergent
- Coco Glucoside – non-ionic, mild detergent
- Cocamidopropyl Betaine – zwitterionic, mild detergent, foam booster
- Sodium Lauryl Sulfate – anionic detergent, skin irritant
- Lauramine Oxide – non-ionic, considered to be skin safe i.e. doesn’t denature/change the shape of skin proteins
- C10-16 Alkyl Glucoside – non-ionic
- Caprylyl Capryl Glucoside- non-ionic
- Cocamidopropyl Hydroxysultaine – amphoteric, mild detergent
- Sodium Methyl Cocoyl Taurate – anionic detergent, considered mild
- Sodium Lauroyl Sarcosinate – anionic detergent
There are only a few different families or classes of surfactants and as you can see many of the types used in the best dish soaps we’ve selected are non-ionic. This is because non-ionic surfactants are in general especially mild to skin, non-sensitizing and safe to use for almost all skin types.
Tip #1 in finding the best dish soap that’s friendly to your skin – look for non-ionic surfactants. If you find one that’s not on the list, Google its name to check.
Extras matter. Many of the best dish soaps on our list also use partnering extras. These add back skin conditioners to help compensate for detergent takeaways. Ingredients like;
- Aloe vera
- Oat flour
All have soothing and hydrating properties which help care for your skin while washing.
Final tip; if you see a formula using only an anionic detergent like Sodium Lauryl Sulfate – avoid it. Anionic detergents are some of the harshest to skin. If they’re not mixed with other detergents, the formula will likely have excellent cleaning power, but for great risk of skin health.
How To Use A Dish Soap?
While it’s pretty self-explanatory there are some extra considerations to bear in mind when using your best dish soap;
You need only a very small amount. In fact, most of the dish soaps on our list call for just 1 tablespoon/3 teaspoons of dishwashing liquid into a standard skin of hot water. An extra way to care for the environment – be sure you’re using just enough.
Hot water is best – hot water makes everything work more quickly (science in action), this means burnt on grilled cheese/in a mug brownie cake and more can wash off cleanly, with just 1 quick soak.
Add your dishwashing liquid to running water – do you remember how we talked about wetting properties of a detergent? For any detergent to work well it needs to be mixed evenly with water. A great way to ensure this is to add your detergent as your sink of water fills. Then wash away.
