The active ingredient in Brake fluid is a glycol, as per the MSDS
(Material Safety Data Sheet):
http://www.warcopro.com/spanish/pages/brakefluid-pdf.htmlGlycols are used in may commercial products and even foods. Look for
Propylene or ethylene glycol in the ingredient list.
Antifreeze is another good source, but has other chemicals in it.
Glyceerine is a close cousin and should aslo work.
Congrats to Volcan for finding a way to reduce the surface tension
in the ink by chemical priming the copper.
Theoretically, you could add the glycol to the ink itself.
