Looking in Jim's newest
book
MMS Health Recovery Guidebook I find a Teeth Brushing Procedure starting on page 73, but no Mouth Wash Protocol. Is that where you found the Mouth Wash Protocol?
The basic procedure is to make up a 5 drop dose of MMS1 and add it to 2 fluid ounces of water. From that solution, you brush your teeth for 2 minutes, 2 or 3 times a day. The protocol you are using is 4 times as strong and that may be the reason for your problems; you seem to be overdosing.
And, if your MMS1 is not properly 'activated', you may end up with too much highly alkaline Sodium Chlorite Solution (SCS = MMS). MMS will burn skin tissue which is what your symptoms seem to indicate. It would helpful to know exactly how you make MMS1 and what color is has after the 30 second activation period before adding it to purified water.
The only Jim Humble approved MMS protocols are contained in his latest book. No approved protocols are available online, although some online MMS protocols may happen to be the same as the books'.
I presume you have his latest book?
