　　鋁合金外殼是一種常用的金屬外殼材料。它具有輕質(zhì)、耐腐蝕、無毒等優(yōu)點，因此被廣泛應(yīng)用于日常生活中。鋁合金外殼表面如果沾有污垢、油污等，不定時清洗，會影響外觀，甚至會導致腐蝕。那么，如何使用正確的方式為鋁合金外殼清洗呢？

　　一、擦拭干凈

　　污垢一般都是油脂、汗水等，它們會使鋁合金外殼變得很暗，為了使其恢復(fù)光亮，需要用干凈的抹布擦拭。

　　二、用肥皂水清洗

　　如果表面污垢較重，擦拭干凈后，可以用溫水和肥皂水將外殼清洗干凈，再用清水沖洗干凈。

　　三、用清水沖洗

　　如果表面污垢不多，可以直接用清水沖洗干凈。然后再用抹布將水漬擦干。

　　四、用抹布瀝干

　　清洗完后，一定要用干凈的抹布將水漬擦干，以免水漬在表面形成氧化鋁，使表面變色。

　　鋁合金外殼如果使用不當，會影響它的使用壽命，因此，使用前一定要清洗干凈。如果外殼表面污垢較重，可以用清水和肥皂水將其清洗干凈，再用抹布擦拭干凈。

　　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.
