Or find an etchant that works at low temperatures (and only attacks the
copper, of course). It would make a change to toss something in the fridge
rather than into a tub of warm water.
This would be something a Peltier module can help with. It can keep the PCB
cool, and be cheap and not take up much space while doing it.
