	Dear Carla,

	Sounds like a good way to clean the knives & save some $.  Traditionally
pith from various reeds has been used, but more recently various companies
have been supplying polystyrene sticks.  Appropriately trimmed packing
peanuts should be fine, (although I wonder if they might be a little firm),
provided you use all the usual care & attention.  However I have always
used 100% ethanol when wiping the edge of the blade.  Distilled water is
for those rare occassions when you need to soak the whole knife to remove
some particularly nasty adherent section.  I section onto 20% ethanol to
remove wrinkles.  This eliminates the need for those various noxious
substances usually waved over the top of the waterbath.  I use Epon resin
&/or its substitutes, Spurrs may have a very low viscosity but I find it
too toxic for all but exceptional circumstances.

	Hope this helps
