Using alcohol spray for ice removal primarily benefits from its ability to prevent thermal shock. When ice is removed using substances that can rapidly change temperature, the underlying materials, such as glass or metal, can suffer damage. Alcohol has a lower freezing point and evaporates quickly, allowing it to effectively break down ice without drastically lowering the temperature of the object being treated. This action minimizes the risk of thermal shock, which occurs when a material expands or contracts too rapidly due to temperature changes.

Other options present various considerations, such as toxicity and availability, but they do not directly pertain to the property that prevents damage caused by sudden thermal changes. Effectiveness against contaminants relates more to cleaning rather than focusing on ice removal, where the thermal stress implications are critical.
