It looks and feels for all the world like laundry detergent. White. Coarse. Powdery.
A mineral mined from vegetation in dry lake bottoms in the Middle East, kelp from Scotland and seaweed from Spain, it’s used to make glass, bricks, paper, rayon, and toothpaste. It cleans silver and softens water.
Its real name is sodium carbonate, but this stuff also goes by soda ash, Na2CO3, and good old Arm and Hammer Super Washing Soda.
Washing soda and I go way back. For years, I have added washing soda to the washer for cleaner, whiter, brighter laundry. More recently, it has become one of the ingredients in our homemade laundry detergent.
Best of all, washing soda (aka sodium carbonate) is cheap. Depending on the source, expect to pay around $.10 per ounce.
More recently, I am discovering that washing soda is much more than a laundry detergent booster. With a powerful pH of 11, washing soda acts as a solvent all around the house, garage. Sodium carbonate removes dirt, grime, greasy build-up and a range of stains.
