I believe he was referring to the H2SO4, sulfuric acid. Liquid nitrogen
would probably be too cold and crack the outer concrete/tiles. I used to
love taking stuff into liquid nitrogen in school and then tossing it
against the wall - what a mess a green grape made. This was until someone
got the neat idea to use a mouse...yuk
Don't they still sell a cooling spray for tracing heat related faults? I
have a case of it (maybe less) that I bought at Tandy on sale some time
back and it lasts a while if you use it carefully. I bought it with the
oncoming of all the BS with restrictions on certain compounds putting holes
in our outer atmosphere and because it was about 1/3 of normal cost. I
don't have a TRS catalog handy but even if the stuff I have is off market,
they should have suitable substitute available. I'm sure MCM, Mouser,
Digikey and others must have something.
