A chemist I know, who did some tests, told me that that was what he found. If
others have found that the sodium salt gives better results then we all have
reason to change. In my current catalogues the sodium salt costs twice as much
as the ammonium.

I have never found that there is a practical difference. In my experience I
have never had any difficulty with staining.

I have never used the sodium salt but I am not sure that it follows that it will
stain more.
