DIY recipe: Laundry Detergent

Because of allergies and sensitive skin of pretty much everyone in our household, I am always very careful with the products I use for cleaning, bathing and washing. For years I used a specific laundry detergent for sensitive skin, but this product was not only extremely expensive, it wasn’t very eco-friendly too. I tried different alternatives after that, from soap nuts to eco-friendly detergents. Although they did the job, I found them very expensive considering the amount of laundry I weekly have to do. I decided to experiment with making my own laundry detergent and stumbled upon many recipes using Castille or Marseille soap. Since I always use Marseille soap to make my own hand soap, I decided to give it a try. It turned out to be a big success. Today I will share my recipe for this easy to make liquid laundry detergent with just two ingredients!


To make 2 liter of liquid laundry detergent, you will need:

  • 2 liter of water
  • 40 grams of Castille or Marseille soap
  • optional: 30 grams of soda (for washing white clothes)


Bring the 2 liter of water to the boil in a big pan. Grate the soap (or use flakes) untill you have about 40 grams of it. When the water is boiling, you add the grated soap to the mix. Stir it around untill it dissolves completely. Then turn off the heat and let this mix cool off. If you would like to add soda to the mix, then now is the time to add it. It is best to let is sit for at least a few hours. After cooling down, you can pour the mix in bottles or an old laundry detergent bottle. Be careful while pouring: the soap can start to foam and make a big mess if you do it too quickly. You can use this liquid detergent like you would use any other detergent. Just add some to the laundry in a dosing ball; half a dosing ball would be enough for clean clothes. If you have very persistent stains in some items, then rub them in with a soapbar or rub some liquid detergent in directly for better cleaning.

We have been happily using this liquid laundry detergent for years now and I can recommend it to anyone. It is great and save to use when you have sensitive skin and it’s all natural. Next to that, you are saving not only saving money on this recipe, but you are also saving the environment. Good on you!

    I also never would have thought about making my own laundry detergent. We have some natural options that are not much more expensive than traditional detergents but I am going to share this anyway. It is always nice to have options to fall back on.

      The more natural alternatives are getting less expensive luckily, but this is still the cheapest option by far. And indeed it is always nice to know that you can make this when you’re out of detergent.
