Boy I'm glad you said that.

After what I was told, I had gone and bought the ice clearing stuff at
the local hardware store that is urea based. Glad I didn't take that to
the airport.

And, yeah, it is only good if you can get the ice to get wet so it
mixes. Here in Ohio where I am, all it does is eat a hole straight down
about 4 mm in dia when the temp is between 20-28. Below that, it takes
a long time before it even melts in pit so it doesn't blow around.

All I intended to use it for is to get the hanger doors open (ours are
on rollers instead of being bi-fold). So far, when ever I get a chance
to go to the airport, the doors are frozen shut (for those of us with
north facing doors).
