You might be thinking of a different kind of, uh, home medical project with the turkey baster

. I never heard of anyone using that for saline wash! Try a real neti pot, the volume is good, and you just want it to wash with gravity, not with the extra force a bulb syringe would impart.
Amazon carries them, and I've even found
this one at CVS. I've had several different models, and like that simple plastic one best. It is a bad call for me to use something ceramic, if I know it's going to be wet and slippery everytime I handle it LOL!
I used to be into mixing my own saline (sea salt + baking soda to buffer it) but I really prefer the little premixed packets for ease. I would sometimes get too much/too little salt and neither feels very good. Exactly the right amount of salt does NOT feel like getting water up your nose at the pool - more like when your eyes are very watery, and your nose is sort of full from that. (Sorry if this thread is derailing into The Ick for anyone . . . )
Daily hygiene is exactly how I think of it (with extra when I need curative help, like to ward off a sinus infection. You can put a drop or two of
something like this (GSE is a natural, powerful antimicrobial) in the rinse to really kick an infection.
This is purely anecdotal, but I feel like I get fewer airborne viruses (and probably bacterial infections, in my case) since I started doing this daily. Salt is death to most microbes - at least, the sort that can threaten us - and it seems to me that one can stay ahead of the invasion timeline for microbes if you rinse out the first battlefield lines once or twice a day (ie, the nose and pharynx.) I am way, way more susceptible to infection (viral, bacterial, fungal) than most people thanks to immunosuppresive drug therapies, and yet I get sick less often than most normal-immunity people. I really think it's the neti pot!
They are also a benefit for people who are prone to middle ear infections, due to Eustachian tube issues; the neti pot can keep inflammation down at the exit of the tube in the throat (which otherwise can close off the exit with swollen tissues.)
It really isn't bad - it doesn't feel like getting water up your nose at all, and it only takes a second. Proper dental hygiene is way, way more involved and (at times).
