Cleansing is important. But just as important is soothing dry irritated nasal membranes. I found some stuff that is a saline and aloe vera based spray that contains calendula and yarrow. It's really great for keeping the sinuses happy, moist and soothed. They also have this stuff for getting rid of congestion that works pretty darn well. It has herbs and such in an aloe and saline base. You should check it out if you have problem sinuses like I do. I found them at www.naturesriteremedies.com and they're not too expensive either.
