The scale seems okay. I agree that you can dissolve the baking soda by heating. That will convert it to sodium carbonate (effectively), which is why it works. Technically, some of the sodium bicarbonate will dissolve and heating will drive off carbon dioxide, allowing more sodium bicarbonate to dissolve. Do you actually want recipe 2, the low-pH version? That is about half as concentrated, for reasons we've discussed.
