How to repair the bright strip of automobile decorative strip?

Toothpaste can be used for automobile bright strip oxidation. Toothpaste contains antioxidants and descaling abrasive particles, which can be polished with a wet towel dipped in toothpaste. You can also use toilet cleaner, which contains dilute hydrochloric acid, which can dilute the oxide. You can wipe it with a towel and wipe it off. After wiping, you need to wipe off the residual acid with a clean wet towel.

Most of the chrome-plated decoration is electroplated on plastic parts, while the metal chrome-plated decoration is relatively rare, because the plastic is light in weight, low in cost and good in electroplating effect.

The mildew and rust on chrome-plated decoration are caused by the adhesion of moldy microorganisms or long-term moisture. With the extension of service time, the chrome-plated decorative parts such as automobile bright strips will be oxidized and blackened due to the factors of manufacturing technology and service environment, which will make the chrome-plated mirror lose its luster and decorative function.

Extended data:

Electroplated bright strips are generally electroplated with copper, nickel and chromium, with the outermost layer being chromium and the second layer being nickel. The appearance of white spots, mildew spots and rust on bright stripes of automobile electroplating is caused by the adhesion of moldy microorganisms and long-term exposure to humid environment. Generally, the chromium layer does not form oxides.

If the attached stains can be wiped off, they can basically be recovered. But if the chromium layer is destroyed and the nickel layer is exposed, it will turn dark brown after a long time and look like an oxide layer. At this time, it is not recommended to use acid-base cleaning agent, which is easy to corrode the inside and become more ugly. If it's too ugly, you can change it for a new one.
