I've heard that the neti pots work well, but if you don't have a neti pot, try a can of "Simple Saline." It squirts way up in in your nostrals continuously to clean out your sinuses. Also, my doc has me take a large syringe and clean out my sinuses daily with 0.9% sterile saline solution (which I buy in bulk). I use to be on all the nasal sprays, but now with just keeping my sinuses irrigated, I find I really don't need all that other stuff.
