Reducing plastic at home, especially the kitchen, is a great step to producing less waste overall. But it’s not just about the waste right? Zero waste dish soaps usually come without plastic packaging – making them zero waste of course – and they are generally more natural than their traditional equivalent. To us, it’s a win-win if you are working to reduce waste and toxic chemicals in the home, but the block version does take a bit of time to get used to.
Zero waste style dishwashing blocks were the go-to in every kitchen before liquid detergent became popular in the mid 20th century. Little did we know that we’ll be drowning in plastic just short of 100 years later and should’ve stuck with the trusty dish soap bar. Life has moved on from the original dish soap bars and you do get lots of options to choose from. Don’t worry they don’t all resemble sunlight soap, which was a laundry soap more than anything, but my parents and grandparents were so fond of it that they used it for almost anything.
I find dishwashing blocks to be less wasteful than their liquid counterparts. With a block, you can rub just the right amount of soap on your dishcloth or brush where you always seem to dispense too much of the liquid soap, especially when doing quick small washing up jobs.
As you may remember from my post about choosing Zero Waste Shampoo Bars, you get two types of soaps; a surfactant or syndet based soap and a soap-based version. For dishwashing, the surfactant soaps are likely to be a bit more effective, but it’s worth giving the soap versions a try to see what works for you.
We tend to lean towards surfactant-based as we live in a hard water area, which can help prevent soap residue and buildup on surfaces, especially in the sink plughole – which can be a pain to remove.
Finding the Best Zero Waste Eco-Friendly Dish Soap
In the spirit of a zero-waste philosophy, aim to look for products that are biodegradable and have reusable or recyclable packaging. Choosing zero waste products one by one is done in small and incremental steps, not all in one go. Use what you have first and then replace the products gradually.

DIY Dish Zero Waste Soap
You can, of course, make your own dish soap at home using a base of Castile soap. For the Castile, you can either buy one such as the Dr Bronner Castile Soap or make your own using a recipe such as this one from the Soap Queen.
Once you have your Castile Soap you can follow this handy tutorial by elsaannukka to making your own dish soap. It basically uses grated Castile Soap, mixed with bicarbonate soda, essential oils and water. Just be mindful that water can encourage bacterial growth within liquid soaps and should ideally contain a form of preservative so if you are set on making your own it’s best to make this soap in small quantities using distilled water. Once made, place it in a soap dispenser that does not encourage bacterial growth such as this one.
Eco-friendly Washing-Up Sponges
So you’ve chosen the zero waste dish soap you’d like to try, the next step would be to replace your plastic-based scrubbers with something more eco friendly. There is no need to just chuck your current scrubby in the bin if it still has life left, you can replace it once it’s dead in the water.
Personally, I like a dish brush like this one and Swedish Dish Cloths like these as they last a really long time. You can also get a scouring pad made of coconut husk or walnut shells. For a full list of eco-friendly washing up gadgets, see our previous post linked below:
