Users who do not want to hide the back panel of their phone usually use transparent frames called jelly frames. Also, many Chinese companies like Xiaomi put such a frame in the box of their phones so that other users do not need to buy a separate frame. But why do so many of these frames turn yellow over time?
It does not become a yellow jelly frame, but over time the yellow color in the body becomes more visible. It should be noted that yellow is used in all transparent materials. But the makers of jelly frames usually add some blue to the body to neutralize the yellow and make it look clearer overall. On the other hand, we must mention the importance of the materials used for this type of frame. Not all clear frames turn yellow over time, and many hard frames, for example, do not have this problem. There are many factors involved in the yellowing of cheap and low-quality jelly frames, some of which are discussed below.
Sun and skin
In the context of the process of destruction of plastic materials in the jelly frame of the two defendants, there is a first line. The first accused is ultraviolet light, of which sunlight is the main source. Ultraviolet light over time destroys the various chemical bonds that make up the long chains of polymer molecules in the case. The same process leads to shorter chains of molecules and thus makes the yellow color more prominent.
The heat also accelerates the yellowing of the frame. The heat of the sun and most likely the heat of the hand are the main source of heat transferred to the frame. In addition, we should mention the natural oils and sweat in the hands, which lead to the depletion of the material in the jelly frame. Even frames that are not transparent change color over time due to these factors.
How to clean yellow jelly frame?
Depending on the age of the frame, there are some tricks you can use to restore it to its “transparent” state. Although it is possible to clean the effects of oil and sweat on the frame, you can not repair the damage caused by ultraviolet rays.
You can use dishwashing liquid, baking soda and alcohol to clean the jelly frame. Most users tend to use dishwashing liquid to clean their jelly frame. In this method, you must first wet the frame with dishwashing liquid and then clean the different parts with a toothbrush.
To use baking soda, you must first spray some of it on the surface of the phone frame and then spread it completely on the surface of the frame using a wet toothbrush. For alcohol, it is also recommended not to pour it directly on the frame. To do this, it is best to first pour the alcohol on a towel or similar napkin and clean the frame with it. Do not overdo it, as alcohol can damage the silicone material in the frame.
Finally, we must say that although these work to some extent clean the jelly frames, you can not stop the process of depletion of the materials used in it. Fortunately, there is a lot of variety in the field of mobile frames, and if your current phone frame no longer looks attractive, you can choose from a variety of frames available in the market, depending on your budget.
