I didn't claim it leaves a totally clean area behind. Getting rid of most of the material is the whole point.

The material I'm wanting to remove is the very material responsible for causing me to be sick. That material floating around, carrying viral packets to non-infected cells, is precisely what I hope to happen.

Also, I'm under the impression that the Alkalol has some ingredients that could play a part in being soap like to the sinuses. Been using it for years, and it hasn't made things worse yet.
