Why Does The Phone Case turn Yellow

It is difficult to bear a good-looking cover with yellow stains; nonetheless, there are several reasons why the phone case may turn yellow. The major reason is due to the sun’s UV radiation. If you often use your smartphone with the cover outside, the case will become yellow after prolonged exposure to the sun.

Of course, UV light isn’t the only factor that contributes to the aging of plastics and polymers. Visible light, high temperatures, humidity, or solvent exposure can all cause a polymer to degrade over time. UV radiation, on the other hand, is frequently the major cause of yellowing.

Furthermore, the continual friction during regular usage, as well as perspiration on the palm or oil on your face, triggers the oxidation process, which turns the mobile phone yellow. However, yellowing has little effect on its essential properties, such as hardness and service life.

Methods I Tried To Remove Yellow Stains From Phone Cases

This is an era of individualism; what is closest to your personality right now? Is it your wallet, purse, keys, or cell phone? Your phone is most likely the answer. The smartphone has become one of those items that I can’t live without.

A transparent and attractive phone cover may enhance the appearance of your phone. Although a phone cover can protect your phone, you need to also pay attention to how you use your phone case in order to get the most out of it. So, how can you get rid of the yellow spots on your case? If you have a restricted budget for a phone case, there are various tricks you may use to reverse the color change.

Soap And Water Method

The most common approach is to soak the phone case in soapy water or laundry detergent water for a time. Then, needing a soft brush or a toothbrush, softly clean the case until the yellow spots are removed. In general, the typical stuff on the phone cover is readily wiped. However, if it has turned yellow owing to oxidation or other causes, it cannot be cleaned.

Bleach And Water Method

Bleach is a chemical that may turn objects white or colorless, which has a clear influence on cleaning silica gel phone cases. Before you use the bleach water, you need to prepare some equipment, such as a pair of plastic gloves, an apron, and a disposable face mask.

Because bleach is cosmetic and irritating, well require these items. Use it after diluting the bleach in the recommended amount, according to the product packing instructions.

The majority of bleach water on the market contains sterilization. After soaking in bleach and wiping it clean, place the phone case in a well-ventilated area to dry.

Toothpaste Method

As I all know, toothpaste can clean and whiten your teeth; the goal of this is to tell everyone that toothpaste is also a very helpful cleaning instrument. Is it, however, up to the task of cleaning a delicate yellowing phone case? No, it does not.

Let’s apply toothpaste to the surface of the silica phone cover and massage it with a cleaning cloth several times. Unfortunately, I discovered that needing toothpaste to clean the silica gel phone case is ineffective. The yellow spots have not disappeared.

According to the results of the real test, the toothpaste cannot remove the yellow spots from the phone cover.

Rubbing Alcohol Method

Alcohol is a wonderful cleaner. Because alcohol has excellent disinfection and volatilization properties, it may be restored to a dry condition quickly after wiping. It does not easily permeate the machine like water, which may result in a power supply short circuit.

Allow your yellowing phone case to soak in water for 10 minutes before wiping the spots away. It works, however it only has a minor effect in removing stains. If you’re interested in trying this approach, you may acquire a bottle of 75% medicinal alcohol.

Regular Eraser

When individuals are young, the most commonly used stationery is a pencil, an eraser is required. It not only removes handwriting from paper things, but it also cleans other objects. It is also appropriate for use on phone cases, particularly those with a matte finish.

You may remove the grime by needing an eraser. So, does it work well with a slick silicone phone case? The dirt was removed after I wiped the softphone cover with an eraser, but the yellow streaks remained.

Hydrogen Peroxide

Do you want to know how to clean a brown-stained transparent phone case? This approach may assist you in removing the yellow and brown stains from your phone case. To get things going, you’ll need a mix of hydrogen peroxide and UV light.

You can get an H2O2-based cream for this. Apply it on the casing and place it under a UV light source. It will be enough if you have a UV nail dryer at home.

Sunlight

If nothing else seems to be working, the sun could be your best chance. Simply place your phone case in the sun to check whether it whitens. However, because the sun changes position repeatedly during the day, the results may be inconsistent.

You may also sand off the top layer of the transparent plastic casing to remove the discolored layer and show a new white layer. All you have to do is sand it off correctly needing sandpaper. After that, wipe down the cellphone case needing a damp towel. This approach will assist you in eliminating a few sections of the yellow regions, but it will not assist you in completely cleaning your phone cover.

Verdict: You Cannot Clean A Yellowing Phone Case

In general, if a phone cover turns yellow due to oxidation, the stains are difficult to remove. As a result, getting a new case is the best option.
