   For glass near anything what dissolves the oil,   
   like acetone, gasoline, synthetic paints dilution solvent.   
      
   For plastic it is very tricky, depending on WHAT plastic.   
   If it is transparent, it is very probably from polystyrene,   
   that dissolves in many organic solvents.   
   Plexiglass and polycarbonate are less probable,   
   but at least the former is very sensitive as well.   
      
   Safe way is warm concentrated detergent   
   and soft mechanical rubbing.   
      
   If I knew the plastic type, some plastic withstand more..   
      
   Ethanol could be partially used too,   
   but not if the clear transparency is priority,   
   as they can dim the surface.   
      
   Concerning solvents,   
   I would not use anything stronger/more polar   
   than technical gasoline   
   ( not engine gasoline as there can be aromatics ).   
   and even this with caution.
