If they are using Type IV to DEICE ice-encrusted airplanes, no wonder they are running short.
Years ago the procedure for heavily iced or snowed airplanes was to use 100% hot water to remove the accumulation, then switch to the deicing fluid du jour to finish the job.
I don't know if they still allow plain hot water to start out. I don't see why not if the job is finished with a proper deicing and anti-icing coat. After all, it's not like the ice and snow doesn't turned to water during whatever process is used.
The key is getting the last spray down correctly with the proper fluid. How the accumulation gets removed doesn't matter as long as it doesn't damage the airplane.
