Recipe for making solid dishwasher soap

Before starting the recipe, it is essential to talk about caustic soda and its precautions for use. The scientific name is sodium hydroxide or sodium hydroxide and it is a chemical product used in the manufacture of soaps.

It has alkaline properties, which means that it has a corrosive effect that can be harmful to the skin. For these reasons it must be used with great care.

When handling this item, wear a mask to avoid breathing in the caustic soda. Apart, latex or garden gloves should be worn along with safety glasses.

Once you make sure to comply with all the precautionary measures, it is time to get down to work. The recipe below is for a 230 gram solid dish soap.


  • 224 grams of recycled olive oil.
  • 56 grams of coconut oil.
  • 78.5 grams of water.
  • 40.5 grams of caustic soda.


  1. Filter the oil as much as you can. The cleaner the better, so using a very small strainer is an excellent idea.
  2. In the container that you will make the mixture, place the soda in the water and stir until it dissolves completely.
  3. When the mixture cools, add the recycled olive oil, stirring continuously. Followed by that, put the coconut oil. Make sure the oils and soda are the same temperature at the time of joining.
  4. Keep stirring for about 1 hour.
  5. Little by little you will appreciate that the mixture is modified in color and thickness, until it looks like a cream.
  6. If you want to add aroma, add a few drops of an essential oil of your choice.
  7. After the mix is ​​ready, you have to put it in a mold. Leave it outdoors for 3 days.
  8. As that time passes, wrap the soap in paper for an additional 25-30 days to saponify.
  9. Store it in chunks or in one piece.
  10. Once that is done, you can now enjoy your soap to wash dishes or clean surfaces that are not delicate.

Caustic soda must be handled with caution, as it is capable of irritating the skin and causing poisoning.

How to dissolve caustic soda correctly?

As we mentioned before, to make soap it must be taken into account that caustic soda reaches high temperatures when it comes into contact with water. Because of that, we will explain the steps to follow to dissolve it safely.

Make sure you comply with the safety measures, that is, wear a mask, gloves and glasses. Then do the following:

  1. Add the necessary water, based on the calculations, in a jug of type pyrex. Ideally, the water should be very cold.
  2. Weigh the caustic soda in the presentation you have and add it to the water, neither too slow nor too fast. You should sprinkle it, because it goes to the bottom quickly. Keep in mind that the soda is always applied to the water and never the other way around.
  3. Use a teflon-type spoon and stir slowly. You will be able to see that a hard layer forms on the bottom and the entire solution will begin to cloud. That's normal.
  4. Hold for a few minutes and keep stirring. Little by little everything will dissolve until it clears up. One piece of information is that the final solution is always crystal clear.

This element must be prepared before use, as soon as it reaches the recommended temperature. Do not let it get colder because it will absorb carbon dioxide from the environment and a layer of sodium carbonate will form.
