Can CS be mixed with a small amount of 
DMSO and then used as a nasal wash?  

We are probably nearly all doing this now - and adding other stuff, to boot, 
such as xylitol.  And sea salt so the mucous membranes are not so uncomfortable 
with the distilled water. Or sniffing it or inhaling it. 
DMSO has been likened to an injection without needles.  Thus there are those 
who add Vit B to it, and get their Vit B shot without a needle.
