DMSO has antioxidant properties and has an alkaline PH. The antioxidant properties use up some of the chlorine dioxide produced in the chlorous acid, and adding an alkaline substance to an acid neutralizes the acid to some degree.
When you neutralize chlorous acid, it becomes less effective.
So, adding DMSO to Miracle-Mineral-Supplement uses up some of the chlorine dioxide and to some extent neutralizes the chlorous acid. I am not sure this is an enhancement.
On the other hand, you may be able to enhance chlorite delivery by adding DMSO to sodium chlorite.
