Due to the good reviews I decided for the de-icer of Caramba. My concern was allergings that there is something greasy on the disc when wiping. Completely unfounded ... I've just tested on my completely icy windscreen, at even my ice scraper has given up. The ice has evaporated within seconds in water and the windows were properly again free of ice and everything without even once to set the scratch. Super product and really recommended to anyone who is in the morning too lazy to scratch or simply want to spare his plate.
