Given the some what "heated" response to my question.... "Can you use steam to clean a lens"?
There's a huge difference between temperature and heat Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. ... Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).3 Sept 2018
Compressed air is describing heat (delta) or the thermal shock is very different to what I'm postulating Using a forensic application of steam is temperature. There's a difference between the two.
It is but a question! I guess I'll need to buy a small steamer and experiment on some cheap eyepieces. Methinks I'll try the scientific method before leaping to conclusions.

I am not sure how steam cleaning goes getting rid of oily residues which would be eyelash oil on the top eyepiece lens.
Bintel cleaning fluid is easy as and I don't think a tremor would affect it.
