I use approximately 1.5 pints of body temperature R/O or distilled water, 6 tablespoons of sole and one to three drops of lugol's.
Start with one drop of Lugol's... more than 2 drops and it can begin to sting a bit. It does not always... would like to know why sometimes it is more sensitive than others at the same dose.
See if that does not help keep your sinuses in top shape... I do this nearly every morning and occasionally, on "high" pollution days before bed at night.
