actually yes. i remember reading something about dry ice being one thing that helps kill off the mold.
this write-up is referring to mold removal from a house, but it explains how the process works:
"Dry ice blasting accomplishes mold remediation faster and more completely than mechanical abrasion. Dry ice blasting does not require toxic chemicals and does not create a toxic dust hazard from remediation operations."
and a little bit more about what the dry ice does:
"Dry ice blasting for mold remediation uses four physical properties of air-propelled dry ice pellets: velocity, abrasion, thermal shock, and evaporation. Dry ice is solid (frozen) carbon dioxide. For blasting uses, dry ice is manufactured in pellets of various sizes appropriate to the substrate to be cleaned. The pellets are hurled from a blasting gun by air pressure, which provides the velocity. When the pellets strike the surface to be cleaned, three things happen. First the velocity of the pellet strikes the substance to be removed. Because dry ice is at a temperature of -109 degrees F., the thermal shock helps loosen and lift the substance to be removed. Finally, the dry ice pellet flashes into carbon dioxide gas, providing more lift to the substance to be removed. The carbon dioxide gas is harmless, leaving no cleaning material such as sand or solvents to be cleaned up after the cleanup."
again, that for ridding it from a house, so your bills would be a much smaller scale cleaning process, lol.
