A custom Chlorine Dioxide solution can be created and used with care. You want to "test" on yourself to ensure that you or your nasal passages are not overly sensitive, otherwise you can reduce the percentage (strength) of the rinse/spray or cease using it.
A general way to create your nasal-rinse:
Add 3 drops from each bottle (3 drops from bottle A, 3 drops from bottle B) together in a plastic or glass nasal spray bottle.
Add your activated solution to 50mL-60mL of water (~1.75-2.1 US fluid ounces).
Spray once or twice into each nostril.
Gently blow your nose, if necessary or desired.
Please keep in-mind that if you have any open cuts or sores, or are recovering from a sinus-cold, you will likely feel a stinging or burning.
Do not over-use the rinse. Your nasal membrane is thin and sensitive. Overuse is not advised.
