i see it isn't save to assume "spiritus" to leave alone plastics.
it is quite the same as denatured alcohol, also the ingredients vary.
i tried to ask the manufacturer of the bottle i have.
has bad webpage, no mailcontact.
so i simply will buy the next bottle of a manufacturer who has web support and ask for the ingredients.
i think the safest would be to try it on a small hidden spot / sample of the material.
or buying very expensive pure ethanol.

that's true.
in US i think it is more common to say Ethyl Alcohol but here definitely ethanol is standard.
i read some good texts about alcohol and plastics, which refreshed my knoweledge about it from school.
there are also some good explanations why different alcohols attack different plastics but the texts are
german and my knoweledge is too bad to translate them, i think you may find similar descriptions in
english on the web.
i hope you get your cartridges unclogged!
(i hope i get mine unclogged too)
we will see tomorrow i think.
the conversion of the printer did work well, it can now be used as a flatbed printer.
i have the transport rollers moving a big pcb (a4). like a hp7475a plotter does.
this is simple enogh for me to make.
on this plate the to be printed pcb is fixed.
