JH says 10 drops of each to approx 30mL of water. My spray bottle is only 60mL, so I use 20 drops of each. I am noticing that my new dropper bottles seem to be making smaller drops than the old ones (25 drops per mL), so I'm beginning to think my next batch will be 1mL of each for 60mL of water. Just thinking -
There's some question re: DMSO and its affect on MMS when added to the solution. Bruce believes that it does not affect the MMS, JH says it will inactivate the MMS in 6 hrs. I can't tell you what the answer is. I've emailed JH, but have received no response, so far. JH has also stated that if you use the skin spray on - say - your arm, and rub in the DMSO, that after about 20 minutes it will have "inactivated" (he uses the word "killed") the MMS.
So, I don't know the answer on this - since I tend to err on the side of caution, I would keep them separate and then use the DMSO on top of the spray. But that's me, and I'm not telling you I have the only answer here
