RE: solvents?

Acetone may work.  You will need lots of patience.  When I used
dichloromethane (methylene chloride, used in paint stripper in GB) it took a
few weeks of soaking and removing the lumps that had spalled off.  I did not
immerse the nst totally, just an inch at the bottom of a GLASS trough with a
glass plate as a lid to stop evaporation and vapour problems.  It was used
as an anaesthetic for minor ops many years ago.  You need nitrile rubber
gloves and eye protection not nitrile rubber) to handle it.  I seem to
remember that there is a hazard if you soak aluminium in it, I cannot
remember what.

I used to use it for removing epoxy from steel parts that had to be re-used.
I used a polypropylene beaker and added water to the dichloromethane.  It
floats on the top and stops evaporation.  The water level has to be well
above the steel or it will rust.  Don't use the water method for a nst.  As
I said in my last post it did not SEEM to damage the insulation on the
windings.

As with most solvents, be careful when you use it.
