I'd be really interested to know how you keep that from spoiling. I used VCO and Lugol's too. A really good quality VCO. About 3 days later, it smelled very spoiled. It is hard for me to believe that 2 substances, which are both antibacterial, would spoil when added together. I use VCO as an exclusive deodorant too; but without Lugol's. I needed the VCO + Lugol's to help me apply Iodine to hemorrhoids. It would be better to apply Iodine alone; but that is too difficult to get it there.
Now, I'm using sesame oil instead. That combination is not spoiling.
