How to Turn Baking Soda Into Washing Soda with One Ingredient and One Hour - Clean Mama

Have you heard of washing soda or super washing soda? It’s a common ingredient in DIY cleaners and sold under the Arm & Hammer brand name. It’s a laundry and detergent booster, odor and stain remover. Washing soda is great ingredient to have in your repertoire.


Super Washing Soda

All it is composed of is sodium bicarbonate (baking soda) and water – that’s it! PLEASE NOTE:  You DO NOT need water for this recipe, the baking soda already has the ‘ingredients’ necessary for the recipe – it just needs to be heated to change into washing soda. If you can’t find washing soda (it’s readily available in the US but not worldwide) or just want to try a little science experiment in your home, keep reading!

  • 2-3 cups of baking soda

Place the baking soda on your baking sheet or dish and then in a 425 degree oven. Stir 3-4 times in the hour. At the one hour mark, check the consistency of the baking/washing soda. If the consistency hasn’t changed, continue baking and check every 5 minutes until it shows a change in the consistency.
