Here are a few from a company that I order "stuff" from.
1. Make toothpaste
You can combine baking soda with 3 percent hydrogen peroxide solution to create a non-fluoride toothpaste.
2. Facial scrub
Instead of going to an expensive spa, make your own facial scrub! Make a paste of 3 parts baking soda to 1 part water. Rub in a gentle circular motion to exfoliate the skin. Rinse clean. This is gentle enough for daily use.
Pat baking soda under your arms to neutralize body odor. Itâ€™s a great alternative to harsher deodorants.
4. Use as an Antacid
Baking soda is a safe and effective antacid to relieve heartburn, sour stomach and/or acid indigestion. Refer to baking soda package for instructions.
5. Treat Insect Bites & Itchy Skin
For insect bites, make a paste out of baking soda and water, and apply as a salve onto affected skin. To ease the itch, shake some baking soda into your hand and rub it into damp skin after bath or shower.
6. Make a Bath Soak
Add 1/2 cup of baking soda to your bath to neutralize acids on the skin and help wash away oil and perspiration, it also makes your skin feel very soft. Epsom salts are pretty miraculous for the bath too.
7. Soothe Your Feet
Dissolve 3 tablespoons of baking soda in a tub of warm water and soak feet. Gently scrub.
8. Make a Hand Cleanser and Softener
Skip harsh soaps and gently scrub away ground-in dirt and neutralize odors on hands with a paste of 3 parts baking soda to 1 part water, or 3 parts baking soda to gentle liquid hand soap. Then rinse clean.
9. Freshen Sponges
Soak stale-smelling sponges in a strong baking soda solution to get rid of the mess (4 tablespoons of baking soda dissolved in 1 quart of warm water).
10. Polish Silver Flatware
Use a baking soda paste made with 3 parts baking soda to 1 part water. Rub onto the silver with a clean cloth or sponge. Rinse thoroughly and dry for shining sterling and silver-plated serving pieces.
11. Clean Shower Curtains
Clean and deodorize your vinyl shower curtain by sprinkling baking soda directly on a clean damp sponge or brush. Scrub the shower curtain and rinse clean. Hang it up to dry.
12. Boost Your Liquid Laundry Detergent
Give your laundry a boost by adding 1/2 cup of baking soda to your laundry to make liquid detergent work harder. A better balance of pH in the wash gets clothes cleaner, fresher and brighter.
13. Gently Clean Baby Clothes
Baby skin requires the most gentle of cleansers, which are increasingly available, but odor and stain fighters are often harsh. For tough stains add 1/2 cup of baking soda to your liquid laundry detergent, or a 1/2 cup in the rinse cycle for deodorization.
14. Remove Oil and Grease Stains
Use baking soda to clean up light-duty oil and grease spills on your garage floor or in your driveway. Sprinkle baking soda on the spot and scrub with a wet brush.
15. Clean Batteries
Baking soda can be used to neutralize battery acid corrosion on cars, mowers, etc. because its a mild alkali. Be sure to disconnect the battery terminals before cleaning. Make a paste of 3 parts baking soda to 1 part water, apply with a damp cloth to scrub corrosion from the battery terminal. After cleaning and re-connecting the terminals, wipe them with petroleum jelly to prevent future corrosion. Please be careful when working around a batteryâ€“they contain a strong acid.
16. Deodorize Your Refrigerator
Place an open box in the back of the fridge to neutralize odors.
17. Deodorize the Cutting Board
Sprinkle the cutting board with baking soda, scrub, rinse.
18. Remove Odor From Carpets
Liberally sprinkle baking soda on the carpet. Let set overnight, or as long as possible (the longer it sets the better it works). Sweep up the larger amounts of baking soda, and vacuum up the rest. (Note that your vacuum cleaner bag will get full and heavy.)
19. Remove Odor From Vacuum Cleaners
By using the method above for carpets, you will also deodorize your vacuum cleaner.
20. Camping Cure-all
Baking soda is a must-have for your next camping trip. Itâ€™s a dish washer, pot scrubber, hand cleanser, deodorant, toothpaste, fire extinguisher and many other uses.
21. Extinguish Fires
Baking soda can help in the initial handling of minor grease or electrical kitchen fires, because when baking soda is heated, it gives off carbon dioxide, which helps to smother the flames. For small cooking fires (frying pans, broilers, ovens, grills), turn off the gas or electricity if you can safely do so. Stand back and throw handfuls of baking soda at the base of the flame to help put out the fireâ€“and call the Fire Department just to be safe.
22. Septic Care
Regular use of baking soda in your drains can help keep your septic system flowing freely. One cup of baking soda per week will help maintain a favorable pH in your septic tank.
23. Fruit and Vegetable Scrub
Baking soda is the food safe way to clean dirt and residue off fresh fruit and vegetables. Just sprinkle a little on a clean damp sponge, scrub and rinse.
24. Clean the Microwave
Baking soda on a clean damp sponge cleans gently inside and outside the microwave and never leaves a harsh chemical smell. Rinse well with water.
25. Relieve Diaper Rash
Put two tablespoons in your babyâ€™s bathwater to help relieve diaper rash.
26. Fresh Flowers
Keep cut flowers fresh longer by adding a teaspoon to the water in the vase.
27. Repel Rain
Wipe your windshield with it to repel rain.
28. Music Fruit Relief
Soak dried beans to a baking soda solution to make them more digestible.
29. Spot-Treat Acne
You can make a paste with baking soda and water. Apply the paste to surface zits. It probably wonâ€™t work as well for deep blemishes.
