How to make your own Magnesium Spray
You will need:
- ½ cup Magnesium Chloride powder or flakes
- ½ cup distilled water
- a bowl or measuring cup
- a spray bottle
Boil the distilled water. Put the magnesium chloride flakes (or powder as on the photo) in the bowl or measuring cup and pour the boiling water over it. Stir well until completely dissolved. Let cool and store in the spray bottle. It can be stored at room temperature for at least six months. I use it daily, also often as a deodorant.
