Yeah, that's true, I thought you meant just direct application of the dry ice  . Plenty of CO2 gas would escape, though. To make the weak acid a little bit stronger and thus more effective for the reaction.. one could increase the solubility of CO2 in H2O by altering the temperature/pressure of the room, I believe
Whoa. Yeah. On the topic of dissolving broken taps, couldn't one find an ion solution in which the ions had a greater (or lesser?  ) standard potential than the ions of the metal used for the tap, but a lesser (or greater?) standard potential than whatever material is being used for the robot? And then just pour that solution over the tap for a redox reaction?
