专家警告说,不要将热水用在袋子或水壶中,以除冰车挡风玻璃上,因为这可能导致裂缝。 Experts warn against using hot water in bags or kettles to de-ice car windscreens, as it may cause cracking. 相反,他们建议使用喷雾除冰器、醋和水溶液,或用纸板覆盖挡风玻璃以防止冰层。 Instead, they recommend using a spray-on de-icer, a vinegar and water solution, or covering the windscreen with cardboard to prevent ice. 有些人建议使用汽车的加热器和风屏风扇,将车内冰融化,尽管这种方法可能会浪费燃料。 Some suggest using a car's heater and windscreen fan set to high to melt ice from inside the vehicle, though this method may waste fuel. 机管局警告不要只留出挡风玻璃的一小部分，称为“舷窗”，因为它可能很危险且违法。 The AA warns against leaving only a small part of the windscreen clear, known as "portholing," as it can be dangerous and illegal.
