Since the Chinese calendar is a lunisolar calendar, the last day of a year is also called lunar New Year's Eve (Traditional Chinese: å¤§å¹´å¤, Pinyin: dÃ niÃ¡nyÃ¨, translated: old, large, huge, major, important year's night).
Aluminum corrodes but it does not rust. Rust refers only to iron and steel corrosion. Aluminum is actually very prone to corrosion. However, aluminum corrosion is aluminum oxide, a very hard material that actually protects the aluminum from further corrosion. Aluminum oxide corrosion also looks a lot more like aluminum (dull gray to powdery white in color), so it isn't as easy to notice as rusted iron.
Remove rust that has caused minor pitting by rubbing the chrome polish onto the rusted areas with fine steel wool. Use the finest steel wool available to avoid scratching the chrome finish. Use aluminum foil and white vinegar if there is still rust on the bumper. Fold the aluminum foil so that it fits in the palm of your hand. Dip the foil in the white vinegar and then rub the foil over the rusted areas.
