What should I do if the mobile phone case turns yellow after being used for a long time? Mobile phone is an electronic product that we can't live without. Many people will buy mobile phone cases. The mobile phone case can protect the mobile phone and also play an aesthetic role. But what if the phone case turns yellow after being used for a long time? Let's have a look.

What should I do if the mobile phone case turns yellow after being used for a long time? Method 1: 1:

If a large number of bacteria accumulate on the mobile phone case that has not been used for a long time, we can clean the mobile phone case regularly at this time, which can not only sterilize, but also remove the yellow and stains on the mobile phone to a certain extent. Generally, scrubbing with toothpaste, eraser, alcohol and detergent can remove dirt well.

If it is used for a long time and the shell has been chemically oxidized, it can no longer be treated by the above method and can only be replaced.

Method 2:

1: If it is a transparent case, you can cut out personalized pictures suitable for the size of the phone case with a blade or scissors, and then insert them into the phone case;

2. If you want to make the phone more beautiful, you can stick paper tape on the outside of the phone case, and then carefully trim it with a utility knife to completely cover the edge of the phone case without leaving any yellow.

3. Color the phone case with pigment, and then do some DIY graffiti or signature as far as you can, then the phone case will be brand-new and unique.

However, I still have to say that I really don't like the above practice! ! It's better to run naked!

Here are three better ways to teach you.

One: gold-plated shell

Electroplating the mobile phone case is to coat a layer of metal on the original mobile phone soft case, which is wear-resistant and oxidation-resistant. The thin electroplated soft shell is very soft, even if it is folded, it will not leave traces or yellow, and it will remain as bright as new even if it is used for a period of time.

Because the electroplating layer is only a very shallow coating, it will not affect the thickness and feel of the mobile phone after wearing it, but will increase the grip of the mobile phone while protecting it. And there are a variety of colors to choose from, which can better reflect individual needs.

Two: PC hard shell

Choose some colored shells or black shells, so that you can't see or even rarely see dirty things. However, it will fade after a long time.

Three: glass shell

Compared with the gold-plated shell, the glass shell has higher hardness, better texture and smoother feel. However, because the glass is too fragile, if it falls from a height, it may damage the shell.

What should I do if the mobile phone case turns yellow after being used for a long time? 2. The mobile phone case belongs to garbage that is difficult to decompose. If you buy a yellow one, throw it away and buy a new one. In fact, this also has an impact on the environment. And now the mobile phone case is not cheap, a mobile phone case is about 20 yuan. In this way, changing a few more mobile phone cases is also a big expense, and recycling should be saved.

In fact, as long as we soak it in water and then brush it gently, we can turn the yellow mobile phone case white and be as transparent as new. However, this kind of water is not simple water. We need to mix it, but the method is simple.

First of all, we prepare a container, just a bigger basin, then pour baking soda, squeeze a piece of toothpaste, then pour alcohol, stir well with a brush, and finally pour some water. After fully stirring, put the yellow mobile phone case in and soak it for 20 minutes. When the time is up, we will take out the phone case and brush it gently, so that the phone case can be scrubbed very clean.

If there is no wine at home, you can also use white wine instead. Prepare a clean basin, pour in white wine, white vinegar and baking soda, then pour in some water, stir it evenly with a brush, and then put the mobile phone case in and soak it for 15 minutes. When the time is up, we will dip some soap in the brush to brush the phone case. With a brush, the yellow phone case can be cleaned, just like new!
