Washing Soda
Sodium carbonate
Washing soda, also known as soda ash, is a common ingredient to use in DIY laundry detergent. It is closely related to baking soda, sharing almost the same chemical structure, but they are not used interchangeably. Washing soda is an abrasive cleaning agent that shines in its ability to remove stains, soften water, and help clean heavy-duty messes. Washing soda is alkaline, making it effective at removing grease and oil. It can be found in most grocery stores near the laundry detergent.

How Washing Soda is Made
Washing soda can occur naturally from deposits in the ground. The most prominent location in the United States with deposits is near the Green River in Wyoming. It can also be produced synthetically, made from sodium chloride, ammonia, and lime (which is called the Solvay process). Generally, it is more cost-efficient to mine the substance rather than produce it synthetically. It can also be made at home by placing baking soda in the oven for one hour at 400°F.
Safety Concerns
Washing soda can be dangerous in large quantities. May cause skin irritation. Use gloves when handling and avoid direct skin contact. Not to be used internally. Keep out of reach of children and pets. It is listed as Generally Regarded as Safe (GRAS) by the FDA, with general precautions on handling alkaline-based substances.
Other Concerns: Do not use on aluminum, fiberglass, or waxed/polished surfaces, as it can cause damage to the finish.
