Unknown liquid in a max/min thermometer

[apollonicon]

I dropped an old, cheap max/min thermometer, which shattered; the organic-smelling liquid splashed into my open fridge. The smell is gut-wrenchingly awful, and the drops of liquid have attacked and melted in spots the hard plastic of my fridge shelves.

 

I have Googled unsuccessfully to find what the liquid might be. It is clear, not tinted. It is certainly not ethyl alcohol. The smell is reminiscent of bonfires and tarry smoke, with overtones of TCP (disinfectant containing halides). The smell is proving almost impossible to remove from the fridge.

 

Can anyone suggest what liquid we might have been exposed to, please?

 

TIA. Apollonicon.
