How To Make Washing Soda From Baking Soda

How To Make Washing Soda From Baking Soda

Washing soda is readily available in the nearby retail store. But if you cannot find it close to your area, you can make it using baking soda.

Baking soda is easy to find and very affordable. The process of making washing soda from baking soda is also straightforward.

Washing soda can be made from ashes of burned plants or heating baking soda in an oven. The heat changes the chemical property of baking soda, turning it into washing soda.

However, handling chemicals at home is highly dangerous, so you need to be cautious.

Ingredients To Make Washing Soda

Ingredients To Make Washing Soda

Your success in making washing soda from baking soda depends on the ingredients you have. Without them and all tools and equipment, you should not try them. Gather the following:

  • 2 cups of baking soda
  • Baking dish
  • An oven
  • Rubber gloves and goggles

Step-By-Steps Instructions To Make Washing Soda

Wear your gloves and goggles to protect you from any chemical spillage. Let us go through the process if you are ready!

Place 2 cups of baking soda in a baking dish. You can use more depending on the quantity of washing soda you want. However, we recommend making small amounts of washing soda for easier monitoring.

Place the baking dish and its content over an oven set to 400 degrees Fahrenheit and heat the baking soda for one hour.

Stir the hot baking soda on the oven and smooth the surface out to form a smooth layer. Continue heating for another one hour at the same temperature as before.

Remove the washing dish with baking soda, now washing soda, from the oven and let it cool. The formed washing soda appears to be more yellowish and coarse texture than baking soda.

Warning: Once the baking soda has turned into a washing soda, you cannot convert it back to baking soda at home with simple methods.

Also, do not heat baking soda over the stove because the heating process results in bubble eruptions, which can be dangerous.

Tips To Store Washing Soda

  • Store the formed baking soda in an airtight container. Label it and keep it out of reach of children and pets.
  • Moisture can ruin your washing soda So, consider putting something like rice or dry crust of bread in the same container as washing powder to absorb moisture. This approach is essential if you cannot find a sealed container to keep water vapor out.
  • Keep washing soda at a stable temperature. Low temperatures will harden it over time, and high temperatures will make it lose oxygen. Oxygen loss leads to degradation, making washing soda less effective. Keep it at a temperature of between 50 to 77 degrees Fahrenheit.
  • Washing soda has an indefinite shelf life but should be stored in an airtight container and kept in a dry place at an appropriate temperature. Otherwise, washing soda can turn lumpy and difficult to dissolve in water. Spoiled washing powder is ineffective in removing stains or softening hard water.
