Types of Zero Waste Dish Soaps

Solid bar soaps

The most popular and widely available are traditional solid bar soaps. 

These bars are typically unscented (some come with essential oils or natural scents) and last a few months with regular use. 

No Tox sells a 22.5 oz block of soap that could last you years (plus smaller sizes).

To use them you rub your sponge or brush against the soap until you have created sufficient lather, then use this to wash your dishes.

Soap bars should be kept dry between uses to help them last as long as possible. 

Consider getting a zero waste soap dish to ensure proper drainage (or DIY one yourself with a bowl and some stones).


Liquids are arguably the most natural transition into a zero waste dish wash routine, but also the hardest to find zero waste alternatives for because they need to be packaged in a bottle.

Your best option if you want a liquid soap is to buy in bulk from a local shop, this way you can reuse containers you already have.

If you don’t have any zero waste stores near you, then you can try out Frillaree’s online refill subscription. Another option is to order large quantities from Amazon.

Dishwasher tablets / Detergent

People often think of dishwashers as environmental no-nos. 

However, several studies now show that newer dishwashers can be more economical than washing by hand

Just make sure you:

  • use eco mode
  • have a full load
  • use a zero waste dishwasher soap

Zero waste dishwasher detergent options will typically come in a cardboard box. 

These dishwasher tablets from ECO Store have been independently tested to ensure an effective clean.

DIY Dish Soap

There’s always a sense of achievement in creating your own eco-products.

We had great success with our DIY eco-friendly toothpastes and sustainable mouthwash makeshift recipe, so we thought why not try out washing up soap as well. 

Creating most homemade dish soaps doesn’t require a degree in Chemistry either, often just 3 or 4 ingredients are needed. 

More on this and some tried and tested recipes later in the article.

When using any natural soap, you will get better results if you apply the soap straight on your dishes rather than make a sink full of soapy water. Rinse your dishes, scrub them clean with soap and rinse again.

Zero Waste Dish Soap Commercial Options:

The makers of these dish soap’s make every effort to be sustainable and create natural products.

We love this soap as a small amount goes a really long way. The soap suds up well and doesn’t leave any residue or aftertaste.

It’s worth noting that due to the lack of preservatives in the bar, you should keep it dry when not in use. Use a zero waste soap dish to drain any excess liquid from the soap after use.

Bestowed Essentials recommend cutting off a small piece and dissolving in hot water if you prefer the feeling of using a liquid dish washing soap.

Bulk Castile Soap

Castille soap is what most zero waste dish wash soap options are based on, but you can also just buy pure castile soap.

The traditionally olive-oil based soap is biodegradable and non-toxic, making it the perfect natural ingredient. 

If diluted correctly, the soap is even suitable for use on the body. 

These days you’ll find different variations made from a variety of different vegetable oils like coconut or hemp oil.

You can find it in both solid soap form and liquid form. 

For the liquid form, to keep packaging down, we suggest bulk buying a concentrated version, which you can then dilute with water based on your needs.

For dishwashing, we suggest a dilution ratio of 1 part of castile soap to 10 parts of water.

Castile soap has an alkaline pH so will react with anything acidic such as vinegar and lemon. This reaction will cancel out the cleaning properties of the soap and leave a white coating on your dishes.

Very hard water can produce the same effect so if you notice this happening, installing a water softener should fix the problem.

Top Tip

Castile soap is so great because you can use it for a lot more than just washing your dishes, it has almost unlimited use around the house. 

It’s cleansing properties make it useful for everything from cleaning your toilet to a bug spray for plants.

If you want to use your soap for other things, check out this super handy dilution cheat sheet.

Another benefit of Castile soap is the price tag, especially if buying in bulk. If you’re looking for a cheap zero waste dish soap, then castile soap is the way to go.

If you’re not able to find any bulk castile soap in your local stores, sustainable options online include:


Check the ingredients of any castile soap you find and make sure it doesn’t contain products derived from animal fat, and that if it contains palm oil, it is from a sustainable source.

The Good Fill

zero waste castile soap

This one is our favourite place to buy castile soap in bulk because it uses the least plastic. 

The liquids are sent in a  BPA-free pouch made with 93% less plastic than a plastic bottle. 

Good Fill asks that you send these pouches back so they can be cleaned and reused, creating a zero-waste process.

They also sell all natural, zero waste dishwasher detergent and liquid dish soap refills.

Homemade Dish Soap Recipe

Homemade zero waste dish soap is easy to make and takes less than 5 minutes. 

Our recipe uses natural ingredients that will clean effectively while also being good for the environment. 

No harsh chemicals are used, so the dish soap will be gentle on your skin too.


  • 1/3 cup of liquid castile soap (add more of this if you find the soap too weak)
  • 1 – 2 tablespoons of baking soda (for really tough stains scrub with some baking soda first)
  • 1 1/2 cups of hot water
  • A few drops of essential oil of your choice (optional)

If you don’t have any liquid castile soap, you can substitute solid soap. 

Any bar soaps you have at home should work, but we suggest using one of the options above or looking for a traditional olive oil soap bar.

You will have to grate the soap (or mix it in a food blender), so you’ll need to use a bit of elbow grease.


  1. mix the hot water and castile soap together / melt the grated soap into the hot water
  2. leave to cool and mix in the baking soda while the mixture is still warm (add any essential oils here)
  3. store in any container you have handy
  4. shake well before use (if you have used a soap block with additives you might need to shake pretty vigorously as the soap can harden)

Homemade Dishwasher Detergent Recipe

homemade dish soap

If you have a dishwasher, you can also make your own zero waste dishwasher detergent. 

Our homemade detergent is much cheaper than the extortionately priced supermarket options. 

Not to mention better for you and the environment.

The amounts given here are just for guidance. You will need to experiment with the recipe as the exact quantities you’ll need will vary on the type of water in your area, plus how dirty your dishes get.

In general, the harder your water, the stronger you should make your detergent. 

Adding more citric acid and using white vinegar as a rinse aid will help get rid of any cloudy residues. You can also try using hotter water or using less detergent.


  • 1 cup washing soda (for cleaning)
  • 1 cup baking soda (helps cut grease)
  • 1 cup citric acid, or lemonade Kool-aid (antibacterial)
  • 3/4 cup of salt (helps soften hard water and adds scrubbing power)


  1. mix all the ingredients together
  2. store in an airtight container, in a cool, dry place
  3. use 1 tbsp per load, for a rinse aid fill the compartment with white vinegar

If you find the mixture hardens after storage, try adding some rice to the mixture, an old pair of tights filled with rice will work and is reusable. 

This will suck moisture out of the mixture and prevent clumping.

To make dishwasher tablets, spoon the mixture into a silicone ice tray and leave out to harden.

Final Thoughts

There are LOTS of zero waste dish soap options out there. It might take you a few tries to find the perfect one for you, but one you have you wont be looking back.

Now you are washing your dishes with zero waste dish soap, why not try de-fluffing your clothes with a zero waste lint brush?
