I have an aluminium surface covered with some plastic, which I intend to dissolve in order to clean the surface. On the note for the plastic I have applied, it says that it contains the following:

  • 2-butanone Naphtha
  • Hexane
  • Toluene
  • Resins

What solvent would you recommend to dissolve this plastic, without damaging the aluminium underneath? Could I simply reapply the solvents that were used initially (naphta, hexane, toluene and the ketone)? Regular petrol should contain up to 15% of the toluene, would it be safe to clean it with petrol?

    $\begingroup$ This isn't what plastic is made of, more like a composition for casting, well, a resin. All other components are solvents and stabilizers, so first I'd try literally one the components you've listed. And VM&P and Naphtha should be together: it's one of the trade names for petroleum ether. $\endgroup$ – andselisk Nov 13 '19 at 8:11
