2 grams in 12 oz seems to do pretty well, note to self, try 3 next time just to see…
I recently broke down and ordered the citric acid to clean my zojirushi. I had cleaned it 4 times before hand with lemon juice; all the scale was gone but I could still taste funky mineralness. Having now cleaned it with the citric acid, I can still barely taste and smell mineral. I think I’m going to have to buy spring water just for my zojirushi, using water filtered from my britta isn’t cutting it. It’s fine in the tea kettle, so maybe the zojirushi just really picks up the city water taste?
Thankfully, the funky taste is so faint I can still enjoy this tea.
