Each temperature comes up with a way of dispatching the surface
tension of water. In the low temperature method, the alcohol already
has neutralized the water's surface tension by the time it squeezes
the local moisture from the air. In the hot steaming, the water vapor
has no surface tension, and settles right into the wool. In 1992
Wally Brooks described acetone as a voicing tool. I could never
confirm this for myself, but it could be that I was trying this
during wood stove season. ayuh.

Not on this matter at least.

Don't knock it until you've tried it, crushed, not stirred and with a
twist of fig fur.
