Things that will cause burning sensation:
- Too much salt
- Too little salt
- Salt not mixed fully
- Iodized or mineralized salt? I’ve never tried these, so I don’t know.
- Water too hot
- Water too cold
- Really, really chemically tap water? I can’t drink our tap water, but it works fine for neti.
I’d also recommend the little packs of mix to start with. I think you actually start with 1/2 package, then move up to a full pack. Once you’ve gotten going and have a feel for it, switch to mixing your own if you’d like. I use pickling salt and bicarb in mine.
An odd “burning” sensation is IME usually salt related. 1/4 tsp per pot seems low to me, but I know some people recommend low-level solutions. I use about 1 tsp per pot, plus a bit of baking soda. I think I worked up to that, though.
Do be sure that it’s mixed really well. I’ve burned my nose on the bottom half of a mix when I didn’t. (I mix enough for two pots plus a bit in a separate container.)
If the water is too hot, I think it feels like “OW HOT HOT HOT”. It doesn’t feel the same to me as a chemical burn feeling. I run mine rather warm, but when I started I tried to get a temp that I could run over my hand & wrist and it felt “body temperature”.
I tried using distilled water, but don’t have any way handy to heat it. Trust me, warm tap water is MUCH MUCH better than cold distilled!
My roomie loves the squeeze bottle. I like the pot better. I use my squeeze occasionally in the shower when I’m in a hurry, but it doesn’t do as good a job.
