It is not the citric acid in the orange that dissolves the toner but the
essential oils. Millions of pounds of orange peels are steam distilled for
this solvent. It is "eco" friendly. but not as agressive as the chlorinated
solvents.
Blending pens, (with toluene) hasve been suggested for pcb transfers for a
long time. Toluene will soften and make the toner sticky. It will transfer
onto porous substrate like texlile and paper. But it is very difficult to
get a continuous film on copper, which is needed for a good reasist.
