15-Minute DIY Laundry Detergent

It’s Thursday and I’m having my first cup of coffee this week whilst Maya is asleep. A little Valentine’s Day treat for myself 🙂 Here in Finland the 14th of February is actually called “Friendship Day” and is a day when you give your friends cards or small gifts or just wish them a happy friendship day. So Happy Friendship Day to all my lovely friends out there!

There’s been some sunshine and it’s been warmer, which means the snow is melting and you can park your car again. I’m probably the only one, but I just hope there will be more snow still as I’m not done with winter yet! I want to go skiing much more, and sledging and skating too.

Anyway, I came here to share a recipe for making your own laundry detergent. The one I’ve used I got from this blog – but since it’s in Finnish I’ll translate it for you. It is so simple and only takes around 15 minutes!

What you need (makes 1,5 litres):

  • 1,5 litres of water
  • 50 grams of Marseille soap
  • 1,5 tbsp baking soda
  • 3-4 drops essential oil if you want to add a scent


  1. Grate the soap.
  2. Boil 1 litre of water and add the grated soap. Stir with a wooden spoon until the soap melts.
  3. Add the baking soda and stir.
  4. Add the rest of the water, stir and turn hob off.
  5. Add the essential oil if you’re using one.
  6. Pour the mixture into a bucket and leave overnight.
  7. In the morning the mixture will probably have settled. Stir with a spoon or by hand.
  8. Pour the liquid into a bottle. I used an old 1,5 litre laundry detergent bottle.
  9. Remember to shake the bottle before using it. You need the same amount of your DIY liquid as you would of a normal liquid detergent when washing clothes.

I have to admit I was a bit skeptic as to wether it would work, but after the first wash I was convinced. I even think it makes the whites a bit whiter, which might be the baking soda? And now after 10 washes or so I’m still happy and will definitely keep making my own detergent from now on.

It is so much better for the planet and my wallet that I don’t see any reason to why I wouldn’t. Plus Lana and Maya have a bit of eczema/dry skin – so I have actually been using the most sensitive, no fragrance stuff already. I’ve sometimes bought the eco detergents too, but they’re just so ridiculously expensive. A batch like this cost me around 1,25€ – slightly cheaper than what you buy in the shop!

Let me know if you try this!

PS. You can buy the Marseille soap from health food stores, I got mine from Ruohonjuuri if anyone’s wondering.
