Use the measuring cup to measure out 1 cup of magnesium chloride flakes and 1 cup of distilled water.
Pour the distilled water into the top part of your double boiler or a heat-resistant bowl set over a pot of simmering water. Warm the water until it’s hot but not boiling.
Gradually add the magnesium chloride flakes to the hot water, stirring continuously with your whisk or spoon until the flakes are completely dissolved.
Allow the solution to cool to room temperature. This step is crucial for safety and to ensure the solution is comfortable to apply to your skin.
Once cooled add approximately 25 drops of your preferred essential oils. (Optional)
Once cooled, use a funnel to transfer the magnesium oil solution into your glass spray bottle. If you don’t have a funnel, you can carefully pour the solution directly from the bowl.
Labeling your spray bottle with the contents and the date made is a good practice. This helps you keep track of freshness and identify the bottle among other DIY products you might have.
