Last winter I was shooting when it was around 0deg and quite humid out. I actually had ice build up on some of my scope lenses and could not think of a way to clear it so I tried to melt it with my breath enough that I could wipe it away. You can probably imagine that was a huge mistake because my breath basically froze instantly to the lenses and made it really unusable.
I was thinking about carrying a small squeeze bottle of alcohol around with me to squirt on the lens if I ever had icing issues again. Any issues with that? Does anybody have any other remedies to an iced scope in cold temperatures?
