I microwave mine. If it starts to cool off too much I just pop it back
in for a few more seconds.
No, I don't do this in the kitchen microwave, I have a spare that I use
in the workshop for various non-food heating tasks.
I'm sure this is less safe than using hot water, but it sure is easy and
fast. I typically only do small boards using less than 50cc of etchant
at a time, so the potential for damage is limited. I wouldn't try it
this way for large quantities of etchant.
