Long-term exposure to sunlight
Prolonged exposure to sunlight is a common cause of yellowing in transparent phone cases. The high intensity of ultraviolet rays in sunlight triggers chemical reactions within the case, gradually turning its color yellow and compromising its aesthetic appeal. To prevent UV rays from impacting the phone case, it is recommended to avoid exposing the phone to direct sunlight when not in use.
Coming into contact with hot objects
Moreover, contact with hot objects can also lead to yellowing of transparent phone cases. When the case comes into contact with heat, its material may undergo changes, causing the color to yellow. During phone charging, which often generates heat, it is advised to remove the phone case to prevent overheating and the subsequent yellowing process.
Contact with oil stains secreted by the skin
In addition, skin oils and residues can transfer onto the transparent phone case when held for extended periods, contributing to its yellowing over time. Regularly cleaning the phone case to remove these residues can effectively slow down the yellowing process. It is advisable to keep the case free from skin oils to maintain its clarity and prolong its aesthetic appeal.
How do you keep a clear phone case from turning yellow?
1、Regularly clean the phone case
Regular cleaning is essential to maintain the appearance of your transparent phone case. Over time, the case can accumulate stains, resulting in a dull, yellowish hue. To prevent this, it is advisable to regularly clean the case. Using a small brush dipped in an appropriate cleanser or baking soda, meticulously clean both the surface and interior of the phone case. Rinse the case with water afterward to ensure it remains clean and retains its transparent and bright look.
2、Avoid contact between the phone case and sweat and oil from the skin
it is crucial to avoid contact between the phone case and sweat and oils from the skin. The oils and sweat from your hands can deteriorate the material of the phone case, leading to discoloration. Therefore, minimizing prolonged contact between the phone and the case is recommended.
3、Stay away from high temperature environments
it is important to keep transparent phone cases away from high-temperature environments. These cases are often made of materials such as silicone, which can undergo chemical reactions under high temperatures, causing discoloration, especially yellowing. Thus, it is best to prevent exposure of the phone with a transparent case to direct sunlight or high temperatures.
4、Purchase a new phone case
if your transparent phone case exhibits significant yellowing over prolonged use, consider replacing it with a new one. Opting for a new phone case can restore the clear and appealing look of your device. Therefore, if you notice noticeable discoloration on your old phone case, it is advisable to replace it promptly.
How long does it take for a clear case to turn yellow?
Transparent phone cases can turn yellow within 1-3 months due to various factors. Typically crafted from materials like TPU (thermoplastic elastomer), these cases can undergo a chemical reaction triggered by exposure to intense sunlight high in ultraviolet rays. This reaction gradually alters the case’s color to yellow. Moreover, regular contact with high temperatures, such as placing the case near hot objects, heat from charging, or extended exposure to high-temperature environments, can hasten the yellowing process.
To prevent yellowing, it is recommended to minimize exposure to sunlight and high-temperature sources. Storing the phone in shaded, cool areas, removing the case while charging, and routine cleaning to prevent the accumulation of skin oils and stains can help maintain the case’s transparency and aesthetic appeal. In such high-temperature conditions, the yellowing process typically occurs over a span of 1-3 months.
Do clear cases always turn yellow?
The transparency of a clear phone case does not necessarily make it prone to yellowing. The material used plays a significant role in preserving the color stability of a clear phone case. Hard materials tend to be more resistant to environmental factors, thus maintaining transparency over extended periods of use. Conversely, softer materials are more vulnerable to external influences like UV rays, high temperatures, and oil stains, which can cause color changes.
The proper use and maintenance of a clear phone case can also impact its color retention. By avoiding prolonged exposure to strong sunlight and high temperatures, as well as steering clear of oily substances, you can reduce the chances of yellowing. Regularly cleaning the phone case to prevent the accumulation of oil stains is also crucial.
