　　铝合金外壳是一种常用的金属外壳材料。它具有轻质、耐腐蚀、无毒等优点，因此被广泛应用于日常生活中。铝合金外壳表面如果沾有污垢、油污等，不定时清洗，会影响外观，甚至会导致腐蚀。那么，如何使用正确的方式为铝合金外壳清洗呢？

　　一、擦拭干净

　　污垢一般都是油脂、汗水等，它们会使铝合金外壳变得很暗，为了使其恢复光亮，需要用干净的抹布擦拭。

　　二、用肥皂水清洗

　　如果表面污垢较重，擦拭干净后，可以用温水和肥皂水将外壳清洗干净，再用清水冲洗干净。

　　三、用清水冲洗

　　如果表面污垢不多，可以直接用清水冲洗干净。然后再用抹布将水渍擦干。

　　四、用抹布沥干

　　清洗完后，一定要用干净的抹布将水渍擦干，以免水渍在表面形成氧化铝，使表面变色。

　　铝合金外壳如果使用不当，会影响它的使用寿命，因此，使用前一定要清洗干净。如果外壳表面污垢较重，可以用清水和肥皂水将其清洗干净，再用抹布擦拭干净。

　　Aluminum alloy shell is a common metal shell material. It has the advantages of light weight, corrosion resistance and non-toxicity, so it is widely used in daily life. If the surface of aluminum alloy shell is contaminated with dirt, grease, sweat, etc., it will not be cleaned in time, which will affect the appearance and even lead to corrosion. So how to clean the aluminum alloy shell in the right way?

　　1. Wipe it clean

　　Dirt is generally grease, sweat, etc. They will make the aluminum alloy shell dark. In order to make it bright, it needs to be wiped with a clean cloth.

　　2. Wash with soap water

　　If the surface dirt is heavier, after wiping it clean, the shell can be cleaned with warm water and soap water, and then rinsed with clean water.

　　3. Rinse with clean water

　　If the surface dirt is not much, it can be rinsed directly with clean water. Then use a clean cloth to wipe the water.

　　4. Wipe dry with a cloth

　　After cleaning, be sure to use a clean cloth to wipe the water, so as to avoid water stains on the surface of aluminum oxide, making the surface discolored.

　　If the aluminum alloy shell is used improperly, it will affect its service life. Therefore, it must be cleaned before use. If the surface dirt is heavier, it can be cleaned with clean water and soap water, and then wiped with a clean cloth.
