Pros and cons about using a mix of Borax/S.hydroxide vs. S.bicarbonate/S.hydroxide together with stock solution of PC-glycol. What effect on grain will they have? If it is made as stock "part B" solution in water, which of them can be expected to have longest shelf life? Can borax or those salts be mixed in glycol too? Would there be a point of that?
