It wouldn't be varnish, it would be lacquer.
A bit of lacquer thinner will remove it.

Ooops. I don't know the difference between varnish & lacquer.

Looking it up by a variety of sources, Wikipedia included, the difference
is interesting ... but after looking that up, I'm still not sure how you
know it's lacquer.

Here's how Wikipedia lists differences:
http://en.wikipedia.org/wiki/Varnish
http://en.wikipedia.org/wiki/Lacquer

Here's a synopsis from multiple web sites:

Varnish:
oil + resin + solvent
always clear
usually brushed on
slow drying
relatively high percentage of solids
usually less durable

Lacquer:
nitrocellulose + solvent
can be tinted
usually sprayed on
fast drying
relatively low percentage of solids
usually more durable
