Not a comment to Paul, but the group as a whole.
Be cautious of these chemicals - absorbing into the body and lungs and
in addition,
some might be solvents to pigments found in shells.  e.g. might bleach
them out in a way.

I'm not a chemist but am cautious with what I use in the shop and home
and yard.
Chemicals can be good and also cause the body damage.

I have worked in FAB lines that are laced in chemicals that would melt a
body or
pass through an arm and dissolve dissolve parts of the bones on the
way.  I fear that many of
the various cancers homeowners get are from various garden/yard chemicals.

Many of these solvents are sold in the paint section of Lowe's or Home
Depot as well.
I like goop off, I believe it is a Toluene based complex of chemicals
product.
(It takes off gum! )

Those of you in large complexes might have access to some of this
through facilities.
