Of course, WD40 is not a water thin Solvent... it is a water displacer.
When I referred to the solvent I had in mind products made specifically to
be compatible with plastic, and to dissolve grease. I have such materials
down in the shop, although right at this moment I can't remember the exact
name... "something 2000" as I recall. I would not suggest that WD40 be used
for this purpose at all.
