I use ACV and baking soda practicly everyday for all sorts of reasons. But when I have Bronchitis or sinus issues or just feel a cold moving in, I steam with baking soda. In a small pot of boiling water with a teaspoon of olive oil that is steaming real good sprinkle some baking soda, about a 1/4 tsp at a time and sniff and inhale while the baking soda is fizzling. It is so soothing, it will move the mucus out and kill molds virus and bacteria. Do it as much as you want its harmless unless you stick your nose in the hot water.
