Alkaline Drinking Water, Natural Laundry Detergent and Agricultural use are amongst the many things Pure Magnesium is used for.   

This product is typically use as a very effective natural laundry detergent. Magnesium when mixed with water, creates hydrogen gas and magnesium hydroxide. This reaction results in an alkaline solution of around pH 10.5 in your washing machine. Negative hydroxide ions reduce the surface tension of the water, making it easier for dirt and oil to breakdown and be washed away. Magnesium cleans your clothes as well as any detergent without using any harmful or allergenic chemicals.
