During winter conditions, a thick layer of ice forms on your vehicle's windshield. Which of the following methods is the safest and most legally recommended to clear it without damaging the glass?

A)Pouring hot water over the glass to melt the ice rapidly.
B)Spreading rock salt directly onto the windshield to dissolve the frozen layer.
C)Using a plastic scraper or spraying an alcohol-based solution over the frozen surface.Correct

A plastic scraper (rasqueta de plástico) safely removes ice mechanically without scratching the safety glass. Alternatively, rubbing alcohol has a much lower freezing point than water (around -114 C), causing the ice to melt instantly without any chemical or physical damage to the car.
