The state law for a black keyboard to turn white is not set in stone, as sometimes it can depend on a lot of factors, including the type of keyboard, how long it has been used, the quality of the material, etc. However, there are some simple ways to solve this problem.

First, you can consider using some household cleaning methods to clean your keyboard. You can use a clean cloth and use a small amount of water or alcohol to wipe the surface of the keyboard. Make sure you don't use too much water and carefully wipe down all the keys and remove the keyboard.

For dirty areas, a cotton swab or brush can be used for a deep clean.

Secondly, another option is to use a specially crafted keyboard cleaner to clean the keyboard. In addition to effectively removing surface dirt, these cleaners are also effective in removing harmful substances such as bacteria and viruses from your mouse and keyboard. It is recommended that you read the instructions for use on the packaging before using the detergent.

Additionally, if you want your keyboard to be more personalized, you may want to consider using keyboard stickers or keyboard cases to decorate your keyboard, which can effectively change the color of your keyboard and turn the original black keyboard white.

In conclusion, it is very easy to clean the keyboard, and it also prevents the keyboard from aging. Most importantly, you should clean your keyboard in time after using your computer to avoid problems such as dust accumulation. <>

It's very simple: buy a bottle of 84 disinfectant, wipe the keyboard with a cotton cloth, and it will be white after a while.

Buckle down the keys and wash them. Remember to dry it before putting it on.

It may also be caused by the oxidation of the plastic on the surface of the keyboard, so there is no solution, and it is not expensive to buy a new one.

With 84, then be careful to corrode the black words on the white keyboard, it's best to remove it and clean it, and the keyboard must also be cleaned up, I cleaned up a lot of things last time,,Then install it.,Turn off the machine and take it down.,Remember to take it one by one.,Lest you don't remember which one is **.。
