The above is a general aluminum alloy polishing process, and different products and requirements may be different. To ensure the best polishing effect, please follow the specific guidelines provided by the manufacturer.

Scratches on the surface of aluminum alloy can be removed by the following methods:

Polishing method: Fine sandpaper or grinder can be used for polishing until the scratches on the aluminum alloy surface disappear.

Decontamination powder method: apply decontamination powder on the surface of aluminum alloy, and slowly rinse with water, and repeat several times until the scratches disappear.

Graffiti brushwork: use a Metal graffiti pen to draw a line on the scratch, and then gently wipe it with a cleaning cloth until the scratch disappears.

Color pencil method: use a color pencil with a color similar to that of aluminum alloy, gently smear it on the scratch to fill the scratch, and then gently wipe it with a cleaning cloth, and the scratch will disappear.

Cleaning agent method: use professional cleaning agent or cleaning liquid, smear it on the scratch and massage it slightly. After the cleaning agent volatilizes, wipe it with clean water to eliminate the scratch.

It should be noted that the above methods are only applicable to minor scratches. For deeper or more complicated scratches, you need to choose a more professional treatment method according to the specific situation or seek the help of professional technicians. At the same time, when using the above methods, it is necessary to protect the surface of aluminum alloy to avoid secondary damage.
