Removing varnish

From: Sabrina Meloni <meloni.s>

Currently I'm working on a 17th century Dutch painting with a
difficult synthetic varnish. The varnish is not yet analysed, but it
looks like an alkydvarnish. It's hard to dissolve but mechanically
it can be removed under the microscope with a scalpel and a little
pressure. To fasten this labour intensive process I'm looking for
other options. I tried with tape to peel it of, but it's not
controllable enough. Has anybody ever tried to use a kind of mini
sandblasting tool, without sand but maybe with something less sharp
like rubber microballoons. Other advice for mechanically removing
this varnish also welcome.
