chocodog for this particular recipe you should not use any metal because of the Bentonite clay.
I made it last night, I can tolerate the taste but not my kids, it tastes salty (and I didn’t even put salt and half the baking soda) and the clay doesn’t taste too good either!!
I am thinking to add Xylotol and I don’t know what else??
I am a little desapointed, used a lot of cinnamon and you can’t even taste it.
As far as the container I have not figure out what to use since using a container and have everyone dip their toothbrush in doesn’t sound like a good plan to me, especially when someone is sick.
