I wrote in my previous post that there are 9 rules, but I actually posted a list of 10 "rules" in the above mentioned thread. However, #10 is not so much a "rule", but it is something that has to be dealt with (regarding the taste of MMS).
As for Jim Humble's book, here is a link to a free PDF of the book:

Be aware of Jim's suggestion about brushing your teeth with MMS. Jim says it is safe for your teeth to do so, but some other people have said that it is bad for your teeth. It might be best to play it safe and avoid his suggestion to brush your teeth with MMS.
Charlotte Lackney's data speaks for itself.
MMS1 (made with 50% CA).. = 2.7 pH (CA = citric acid)
MMS1 (made with 4% HCL).. = 2.5 pH (HCL = hydrochloric acid)
This recipe made with CDS = 4.8 pH (2 tests average 4.8 pH with 2 different CDS batchs; 1 old, 1 new)
This recipe made with CDH = 3.5 pH (tested with freshly made CDH)

CDS seems to be the best of the bunch. Some people add baking soda to increase alkalinity. Test for yourself. Neutral is 7.
