Low and Zero Waste Dish Soap Options:

Ingredients to Avoid in Zero Waste Dish Soap

Castile Soap

Castile soap is a fantastic option for washing your hands or your body in the shower. The problem with using it for dishes is that Castile soap reacts with minerals in hard water, leaving a film behind on shiny objects (like dishes). That film is also referred to as “soap scum.” It isn’t harmful, but if you’re looking for that shiny, clean finish on your dishes, it will be difficult to achieve when using Castile soap. 

Palm Oil

The overproduction and overuse of palm oil is heavily contributing to deforestation. This means multiple endangered species are going extinct, among other environmental concerns. If you are interested in a high-level overview, check out this article from One Green Planet. With that said, palm oil is a popular ingredient in a lot of soap recipes, including “low waste” options. 

Unless otherwise noted, all of the dish soap options below are made without palm oil.


If you’re open to dish soap bars, then there are plenty of great options available. If you can find them locally, that’s your most sustainable option. Alternatively, dish soap bars can be delivered plastic-free to your door. Keep reading for some great options below.

If you’re committed to liquid dish soap, purchasing in bulk at a local refillery is your best zero-waste option. If there isn’t a refillery available near you then your next best bet is purchasing your soap in bulk.
