Vigon is a totally different kettle of fish. The Zestron you are talking about is an
HCS solvent (so-called "semi-aqueous"). Vigon is a saponifier and is used in an aqueous
solution. It is not "semi-aqueous" in that the residues are not dissolved and then the
dirty solvent is cleaned off in a fully aqueous cycle. Does "semi-aqueous" mean that
the cleaning product has the chemical formula HO0,5 ? :-)
