IIRC vinegar dissolves water deposits. Is that right?
And is wine vinegar as good as white vinegar? Apparently I used the
bottle of white stuff.**

My humidifier that goes into the heating duct wasn't working, and all
that seems wrong is that the inlet screen is clogged. I couldn't get
the whole thing apart, so I have a little bigger part soaking in wine
vinegar! Is that as good as white vinegar?

**(I don't know how since I barely cook. Must have been to dissolve
something else.)
