How to Use Baking Soda

Last Updated: September 15, 2021 References Approved

Baking soda, which is also known as sodium bicarbonate, is a type of salt that often comes in the form of a white powder. Because baking soda is edible and environmentally friendly, many people like to use it around the house in place of commercial cleaners. But baking soda also has many other uses, including eliminating odors and helping foods rise.

Cleaning with Baking Soda

1
Make an all-purpose spray cleaner for the house. In a spray bottle, combine 1 teaspoon (5 g) of baking soda, ½ teaspoon (2.5 ml) of liquid dish soap, and 2 tablespoons (30 ml) of vinegar. Shake the mixture and allow it to bubble and settle. Then, fill the bottle the rest of the way with warm water. Always shake the bottle before using.^{[1]

- This spray can be used in the kitchen and bathroom, on floors and walls, to clean the sink and refrigerator, and to wipe down appliances and other surfaces.
- Baking soda is slightly alkaline and mildly abrasive, so it can be used effectively as a cleaner around the house.
2
Make a tougher scrubbing paste for multipurpose cleaning. For stains, tough jobs, and baked-on foods, make a baking soda paste by combining equal parts baking soda and coarse salt. Then, add a few drops of liquid dish soap and just enough water to stir the mixture into a paste.^{[2]

Fill a large bucket, footbath, or baby bath with warm water and add 2 tablespoons (30 g) of baking soda. Soak your feet or hands in the bath for about 10 minutes to soften skin. For diaper rash treatment, dip the baby’s bottom in the water.^{[16]

Method 4 of 4:

Using Baking Soda in Cooking and Baking

1
Add 1 teaspoon (5 g) to baked goods to help them rise and spread. When the baking soda combines with liquid and acid, it creates carbon dioxide bubbles that will help breads, cookies, and other baked goods to expand. You can add baking soda to any recipe that contains a liquid (such as water or milk) and an acid, such as:^{[18]
X
Research source}
- Lemon juice
- Cream of tartar
- Sour cream
- Buttermilk
- Vinegar
2
Neutralize the acidity in foods. The alkaline nature of baking soda will cut the acidity in foods that have too much. For instance, if you're making tomato soup or sauce and find that it’s too acidic, stir in 1 teaspoon (5 g) of baking soda to neutralize the flavor.^{[19]

Question

Is it safe to use baking soda for my face and as a toothpaste?

Community Answer

Yes. Baking soda can be abrasive, however, so be gentle.
Question

How does baking soda react on hands?

Community Answer

Unless there is something fairly acidic on your hands, you won't see much of a reaction. It's safe to use and acts as an antiseptic.

Warnings

Using baking soda to exfoliate skin or as an ingredient in deodorants, skin care, and hair care products isn't recommended. The pH of skin and your scalp is typically between 4.5 and 6.5 (slightly acidic), whereas the pH of baking soda is around 9 (alkaline). Using something with that high a pH on your skin or scalp can cause rashes, dry skin, and damage.

Baking soda can be used as an effective antacid, but it’s not recommended because of the high sodium content. Each teaspoon (5 g) of baking soda contains over 1,200 mg of sodium, whereas the recommended daily intake is between 1,500 and 2,300 mg.^{[23]
