Home-made laundry soap

The magic formula, coming directly from our grandmothers, is here for you!  For those who want to make their own laundry soap or a stain remover, we have prepared the best recipe of all time.


  • 1.5 kg of fat (animal origin or vegetable butter such as shea or mango butter)
  • 460 g of vegetable oil (olive oil, palm oil)
  • 700 ml of water (preferably rainwater)
  • 270 g of caustic soda (base)

In a large bowl of resilient plastic or stainless steel, slowly add caustic soda into water (never reverse). It is best to add it slowly, spoon by spoon.

Don’t put all the caustic soda immediately into the water because a strong reaction will occur and the compound could get out of the pot.

As soon as you add the first spoon, the reaction will come immediately – the water will begin to boil and fizz.

After slowly adding all the base, use a wooden shaker (not metallic) to stir it and slowly add dissolved solids and oils, which should not be hot but warm.

Stir the compound until you get homogeneous molasses, like dense honey.

You can mix it with a mixer, but don’t mix for too long (up to ten minutes) because the mixture will start to harden very soon. If you like, you can also add some essential fragrance oils (about a dozen drops), such as lavender oil, melissa or cinnamon oils.

Lay your mold with aluminum foil or some other foil, and then slowly and carefully put a warm soap in it. After 24 hours, cut the soap into desired shapes (cubes, etc.) or remove it from the mold (if the mold is smaller) and allow it to dry in the period of 6 to 8-weeks.

Any container of milk or juice can be used as a mold.

A warm procedure

The first part of the soap creation is exactly the same as preparing the soap in a cold process, but the difference is that the water and the fat are poured into a stainless steel bowl into which an active (caustic) soda is slowly added, and after the initial connection (when the mixture is slightly calmed down and no longer shows any signs of boiling) you need to put all the compound on light fire and occasionally mash until it becomes dense like sugar molasses.

This could take hours. You need to be careful because the mixture will become denser.

After three to four hours of simmering, the soap will become very thick and it needs to be quickly poured into molds.

Soap will quickly harden and after a few hours, it can be cut to desired shapes. It should also be left in an airy room, to complete the process and completely drain the caustic soda.

It is precisely the cooking part which accelerates the process of vaporizing the caustic soda, so this soap is ready for use much more earlier. After two weeks of drying, when the caustic soda completely evaporates and the whole process will be finished, the soap can already be used.
