Fill a clean plastic spray bottle with 4 cups of warm or hot water. The heat enables the baking soda to dissolve.
Add 1/4 cup of baking soda and 2 teaspoons of ammonia to the bottle. Shake the bottle to dissolve the powder.
Add 10 drops of the essential oil to the container. Many people use a citrus oil to give their home a fresh, clean scent. Lemon or orange essential oils provide this type of fragrance. Other pleasing fragrances are cinnamon, vanilla and lavender. Use whatever scent you prefer.
Screw the lid onto the plastic bottle. Shake it to mix the solution.
Spray the deodorizer in the air in rooms with an offensive odor. The baking soda and ammonia neutralize the odors and the essential oil adds an attractive scent.
