Lorel (WA) on 04/10/2022: 
Take 35% food-grade H2o2 and dilute it to 3% (one oz of food-grade 35% H2o2 + 11 oz of distilled water = 3% of Food Grade H2o2). Then put the 3% in a spray bottle. Spray into your nose and mouth every 2 hours and when spraying into the mouth breathe in deeply.
My sinus infection and all related symptoms were gone in 48 hours.
