How to Use Baking Soda

Co-authored by Jonathan Tavarez

Last Updated: February 22, 2024 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.

Method 1 of 4:

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.
- 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.^{[1]

- Dishes with baked on foods
- Storage containers with sauce stains^{[2]

Expert Interview. 13 September 2019.} You can use baking soda to absorb grease and oil in the kitchen, on dishes and appliances, and even in the garage floor or on the driveway. For oil and grease spills outside, sprinkle baking soda over the spill and leave it to absorb for about 10 minutes. Scrub the area with a brush and rinse it with a hose. Inside, sprinkle baking soda over the spill and wipe it with a clean cloth after 10 minutes.
- To remove grease from dishes, add a scoop of baking soda to the soapy dishwater and soak the dishes for 10 minutes before scrubbing clean.^{[5]

Our Expert Agrees: For stovetop cleaning, you can just pour baking soda right over any grease and grime. Let it sit for a few minutes, then wipe it away with a scrub and a damp wipe. You can also sprinkle baking soda over an oil stain in your driveaway. Scrub the stain with a bristle brush, then rinse it away with water.

Boost your laundry detergent. Baking soda can get your laundry cleaner by cutting grease, whitening, and eliminating odors. Just add 1 cup (240 mL) of baking soda to the washing machine drum and wash your clothes using your regular detergent and washing settings.^{[6]

Our Expert Agrees: Place some baking soda in a small open container inside of your refrigerator to help reduce bad odors and keep your produce fresh longer. You can also remove foul odors from your household drains by pouring half a cup of baking soda down the drain, followed by half a cup of vinegar. When you're finished, pour 4 to 6 cups of hot water down the drain.

Clean brushes and combs. In a small bowl, combine 1 cup (240 mL) of warm water and 1 teaspoon (5 g) of baking soda.^{[13]

Research source} Place your combs and brushes into the bowl and let them soak for about 30 minutes to remove oils and residue. Remove the combs and brushes from the solution and rinse them with fresh water. Pat them dry, and leave them to air dry completely.
- You can also use this same method to clean and deodorize toothbrushes, retainers, dentures, and other oral appliances. Use 2 teaspoons (10 g) of baking soda per 1 cup (240 mL) of water to clean these items.^{[14]

Add it to the bath to soothe and soften skin. Small amounts of baking soda can be dissolved in water to help soften skin and even alleviate diaper rash. 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.^{[15]

- In very small amounts, baking soda can be safe to use for diaper rash because it will help to neutralize the acid (found in urine and feces) that’s causing the rash.
- Only use baking soda sparingly and in small quantities on your skin, as the high pH can irritate and damage the skin.

Method 4

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:
- 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.^{[16]

Research source}
- You can also add baking soda to lemonades, store-bought soups and sauces, canned tomatoes, and even tea to cut the acidity and bitterness.^{[17]

3
Make your own baking powder in a pinch. You can make your own baking powder by combining 2 teaspoons (7 g) of cream of tartar with 1 teaspoon (5 g) of baking soda. Whisk the powders together thoroughly to produce 1 tablespoon (14 g) of baking powder.
- Use equal parts homemade baking powder as a substitute for the store-bought version.^{[18]

Wet your produce with a small amount of water and sprinkle baking soda over the skin. Scrub the fruit or vegetable with a damp cloth to remove dirt and residue. Rinse the fruit or vegetable with fresh water before eating or preparing.^{[19]

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.^{[20]
