Ice is not only found in mixed drinks.
Speaking of methods of removing ice from helicopters....
Operating off the coast of Greenland on the back end of an icebreaker we used covers over the canopies of our Sikorsky and our Bell. We also covered the main and tail rotors as well as the rotorheads. Normally the covers protected the helicopters from snow build up. On one occasion the sea was a bit rough and when the ship came about it raised a big wave and the wind blew the seawater up onto the flight deck and covered the left sides of the two helicopters as well as the blades with about an inch or more of ice.
We removed the ice buildup with a Herman Nelson gas heater, which normally was used for preheating the engines

Thanks for your help so far but I am really interested about inflight icing even if there are photos from inside looking out at an iced up screen....

TD,
IIRC, there are some icing pics on the photos thread: you'll have to find them, but I recall hosting some of trials in Canada.
Ned's recollections of the forced overnight: de icing of freezing rain at the Hotham helipad (6000ft AMSL) was done very carefully, mostly with warm water, a heat gun and some plastic scrapers after the freezing conditions lifted. Took nearly three hours

The National Research Council of Canada did a lot of work on icing of helicopters. They used to have an ice generator at Ottawa airport and flew various helicopters into the ice to study the effects. They should have lots of photos - I've seen a few of them in various magazines. Here's their address:
