The Many and Varied Uses of Baking Soda

Baking soda, may be a weak pH base, but it is not weak in its uses!

Sodium bicarbonate (NaHCO3), the scientific term for baking soda, is a weak base. It is most commonly used for baking and helps to regulate pH. Its pH value is 8.31, while most tap water has a neutral pH value of 7.

When baking soda mixes with either an acid (i.e., stomach fluid (hydrochloric acid), most fruit juices, cooked beans, etc.) or an alkaline substance (i.e., spinach, broccoli, onion, etc.), it has a neutralizing effect on it. Baking soda is perfect for neutralizing acidic odors and maintaining a neutral pH which is perfect for doing things like settling an upset stomach or enhancing your laundry detergent’s cleaning power. It also has a gentle abrasive ability to help scrub without causing harm.

Baking soda deodorizes, neutralizes, and cleans all without the cost or toxicity of most commercial products.

The Many Uses for Baking Soda

Personal Care

  • Freshen Your Breath - Mix 1 teaspoon of baking soda in a glass of water. Swish, spit, and rinse. The baking soda will neutralize mouth odors and leave your mouth feeling fresh.

  • Polish Your Teeth – Baking soda is used in many commercial brands to whiten and freshen your teeth. Brushing with baking soda can help 1) prevent gum disease, 2) fights bad breath, 3) whitens teeth, and 4) relieves mouth ulcer discomfort all while polishing your teeth. And, baking powder is antibacterial.

  • Make Your Own Deodorant – In a pinch, you can sprinkle it on as a natural deodorant. It may be a little much for sensitive skin, so be careful, but it can work if there are no other options.

  • Gently Exfoliate – I say GENTLY exfoliate your skin. Mix a paste (about 3 parts baking soda to I part water) and gently rub in a circular motion, or use a damp cloth to clean the area.

  • Relieve Skin Irritation - Add a cup of baking soda to bathwater to soften your skin and relieve skin irritations. It will leave your skin feeling soft.

  • Relieve Insect Bites – Make a past of baking soda and water and apply to skin. This will relieve most bug bite discomfort.

  • Stripping Dye from Your Hair – Using baking soda on your scalp can change its pH and cause damage. Using it too often on your hair can cause it to become brittle, but if you need to strip a little dye from your hair, you can create a paste with water, apply and leave on for a short time, and then rinse. Before doing this, however, I would do more research or ask your hairdresser for help.

  • Keep Your Brushes and Combs Clean – Soak combs and brushes in a solution of water  (1 cup) and baking soda (1 teaspoon). Rinse and dry thoroughly. The baking soda will help remove the oil and product buildup.
