4 Natural and Zero Waste Dishwashing Soaps
Zero waste dishwashing soaps was a change I made pretty easily for just myself. However, it took my significant a little bit of convincing. But after presenting him with these 4 options, he found one that he liked and we have never looked back!
The reason I wanted to switch from our Dawn dish soap to a zero waste dishwashing soap option was twofold.
1. I’m a huge fan of easy, simple DIY’s that replace chemical laden traditional products, and dish soap is no different. For example, Dawn’s dish soap contains Sodium laureth sulfate (causes water toxicity, damage to vision, cancer, and issues with the endocrine system), methylisothiazolinone (causes acute water toxicity), among others. Plus, the fragrances in Dawn soap are also known to cause biodegradation.
2. Dawn dishsoap comes in plastic. As I am living low/zero waste, this was a no-go for me of course.
So, I make my own! But there are a couple of different options out there for a non-toxic, more sustainable, DIY dish soap (and most are super cheap)!
Option 1: Bar soap
Super simple, just use a bar soap. I personally don’t care what kind of bar soap I use to wash dishes as long as the ingredients are simple and smell nice.
However, some care for a certified streak-free shine to their dishes, which is also achievable with bar soap too! And a bigger plus, you might have an easier time finding these made without palm oil. ( Read why certain palm oils are bad for the environment here.)
This Handmade Castile Dish Soap is very popular for both hand and dish washing.
Pair with a Walnut Dish Sponge or a brush for a more sustainable cleaning set up.
Quick tip: if your dish soap doesn’t have groves to help with drainage, place some rocks on the bottom. This helps prevent it from getting a goopy bottom.
Option 2: Liquid Soap from a Grated Bar
In all honesty, I haven’t tried this option yet. But I’ve heard amazing things and it is a recipe from Zero Waste Chef, who I really admire.
Option 3: Liquid Soap from Sal's Suds
While I can only find this in a plastic bottle, Sal's Suds is super concentrated and a large bottle should last you a long time. They do use palm oil, but they seem to have processes in place that support a sustainable agriculture and trade practice.
I urge you to do your own research though (and not just for this, but everything you buy) and see if it aligns with your values.
Ok but before we dive into the recipe, what’s the difference between their Castile Soap and Sal’s’ Suds?
Castile Soap reacts with the minerals contained in hard water, leaving behind an insoluble film that’s commonly called “soap scum”. While this doesn’t affect the cleanliness of your dishes, some prefer that squeaky clean shine to their dishes. Which is where Sal’s Suds comes into play.
Sal’s Suds is a formulated biodegradable household cleaner that doesn’t react with hard water. It rinses cleanly and leave surfaces sparkling.
For a more in depth explanation of the difference between the two, see this article.
¾ cup of water
¼ cup of Sals Suds
15ish drops of essential oil (for smell, but I personally love the pine scent of Sals’)
1 ½ tablespoons of a liquid oil (like olive, jojoba, avocado etc - this will help provide some moisturize if you use your bare hands when washing up)
Combine all ingredients into a soap-dispensing bottle. Yep, that’s it. It’s that easy. You’re welcome.
Option 4: Common Goods Bulk Liquid Dish Soap
I feel like I’ve been stumbling upon Common Goods Refillable Dish Soap around so many Boston stores lately and I’m loving it! Their ingredients aren’t scary at and the bulk options show their committed passion for sustainability.
This is also an option I haven’t tried personally yet, but they seem to have rave reviews (although it can seem a little pricey).
Wrapping it up!
I hope this inspired you to find a more sustainable dish soap! Whether you make it or buy it, chances are you'll also be saving a bit of money too, which is always a win in my book :)
