Baking soda can be used in laundry; a half-cup added to the washer is one way to boost laundry detergent and bleach. Baking soda also softens clothing. It is safe in both high-efficiency and standard washing machines.
Adding half a cup of baking soda to the laundry regulates the pH level in the water by keeping it from becoming alkaline or acidic. Half a cup of baking soda also balances detergent so that clothes feel less stiff. A paste of baking soda and water is also useful for cleaning irons. It acts as an abrasive and removes starch and scorch deposits.
