I drink purified water and saline through my nose to cleanse my sinuses. It requires mind concentration, and suppression of subconscious gag reflexes. When I spray paint in haste without a mask or I am exposed to lots of dust particles, then its time to cleanse my poor sinuses. I do not recommend tap water. It can burn the very sensitive sinus linings with the minutiae amounts of chlorine and fluoride found in most tap water.
