How to make homemade soap with vinegar and baking soda

Making homemade soap without the use of caustic soda is a safe and natural option for those who want to avoid harsh chemicals.
By using simple ingredients such as vinegar and baking soda, you can create effective cleaning bars for cleaning your home or laundry. This detailed guide will show you how.
Ingredients needed:
- 2 cups baking soda: Natural cleaning agent and deodorant.
- 1/2 cup white vinegar: Powerful natural disinfectant and polisher.
- 1/4 cup cornstarch (optional): Helps improve the texture of the bars.
- 10-15 drops of essential oil: To add fragrance and antibacterial properties. Lavender, tea tree, or lemon essential oils are great choices.
- 1/4 cup grated Marseille soap (optional): Adds extra cleaning power.
Tools Needed:
- Large bowl
- Spatula or wooden spoon
- Silicone Molds for Soap
Method:
- Preparation of the dry ingredients: In a large bowl, mix the baking soda and cornstarch (if using). Add grated Marseille soap as well, if you want to further improve the cleaning power of your bars.
- Adding vinegar: Slowly, add white vinegar to the dry mixture. You will notice that a slight effervescence occurs due to the chemical reaction between vinegar and baking soda. Stir constantly until the effervescence subsides and the mixture becomes homogeneous.
- Essential oils: Add the essential oil drops to the mixture and continue stirring until all the ingredients are well combined. Essential oils not only provide a pleasant fragrance, but also add antibacterial or relaxing properties, depending on the type of oil used.
- Forming: Pour the mixture into the silicone molds. Press the mixture firmly into the molds to make sure it is compact and free of air bubbles. Level the surface with the spatula or wooden spoon to obtain even bars.
- Drying: Leave the molds in a dry, well-ventilated place for at least 24 hours, or until the bars are completely dry and solid. If necessary, let them dry further for a few days.
- Removing from the Molds: Once the bars are dry and solid, remove them from the molds. If they are still moist or soft, let them dry in the open air for a few more days until they reach the desired consistency.
Using Soap Bars:
These soap bars are perfect for various household uses:
- Surface cleaning: Use the bars to clean sinks, countertops, and other washable surfaces. Simply rub the bar directly onto the damp surface and then rinse with water.
- Laundry detergent: For natural laundry, grate a small amount of the soap bar into the drum of your washing machine or dissolve it in hot water before adding it to your laundry.
- Hand Cleaning: You can also use these bars to wash your hands, although they don’t produce as much lather as traditional soaps.
Creating soap bars with vinegar and baking soda is an eco-friendly and safe way to have a multifunctional cleaner for your home and laundry. Not only does this method avoid the use of caustic soda, but it also employs readily available and environmentally friendly ingredients. Try this recipe for a natural and effective alternative to commercial cleaners.
