Can spray cleaners lead to sinus Problems?
Yes. Cleaners can definitely motivation you to have issues beside your sinuses. You are obviously sensitive to the chemicals surrounded by 409 so try switching to a different cleaner other than 409. I recommend something approaching Clorox Multi-Surface. It comes in a bluish bottle and at hand is not really a strong odor. If you do not like the Clorox later I recommend when you clean to own excellent ventilation.
