mm spake thus:

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?

Yes, vinegar, being a mild acid (acetic acid) dissolves all kinds of
mineral deposits. Most people prefer white vinegar, as it's cheaper and
doesn't leave any stains.

Since it's relatively weak acid, time is your ally: if the stuff isn't
coming off right away, just let it soak some more.
