Most of the common organic solvents are regarded as noncorrosive, but stainless steel can be attacked by formic, acetic, and propanoic acids.

Corrosion of stainless steel by organic solvent mixtures, Alice Y. Ku , David H. Freeman, Anal. Chem., 1977, 49 (11), pp 1637–1638 DOI: 10.1021/ac50019a044

Are there some aromatic hydrocarbon that attack stainless steel? Which organic solvents can corrode copper and aluminium?

Picric acid (2,4,6-trinitrophenol) is an aromatic compound has been used as an etchant in the past. Picral is an ethanol solution of picric acid and could etch steel. Look up www.metallographic.com/etchants/etchants.htm

  • $\begingroup$ In fact, I think this can stand well as an answer to that question. It would however, be really nice of you to be more elaborate on it. When was it used as a solution? What references do you have? etc etc. $\endgroup$ – M.A.R. Aug 1 '15 at 19:30

  • $\begingroup$ A lot of the strong organic acids like formic corrode aluminium. books.google.co.jp/… $\endgroup$ – user2617804 Aug 5 '15 at 12:57
