How to clean the phone case when it gets dirty

Depending on the material cleaning method, see which material you have.

1. Silicone: The advantage is that it is cheap, and the disadvantage is that it is easy to turn yellow, not suitable for cleaning, and is almost a disposable consumable.

1. Stain remover or bleach is suitable for tea, coffee or other stains.

2. Organic solvent or alcohol is suitable for mobile phone cases that turn yellow after a long period of use.

Note: However, these methods will not completely solve the problem of yellowing, and will damage the silicone shell of the mobile phone, making the mobile phone case gray and shiny.

2. Plastics: There are domestic plastics and imported plastics, no matter which one is slightly higher and easy to clean. But scratches can't be removed.

1. Alcohol Wipe with a small amount of alcohol with a paper towel, pay attention to the softness of the paper towel is better, and it is not easy to drop the confetti, otherwise the phone case will have scratches.

2. Toothpaste Take a small amount of toothpaste with a paper towel to wipe the shell, and then wipe it with a moist towel, and generally you can also remove the screen scratches, which can restore the posture of the phone case. Note: You can't use a toothpaste that's grainy, as it will scratch the phone case.

3. Eraser I won't say much about this method.

3. TPU: Moderate, good transparency, can not be cleaned after yellowing.

Fourth, imitation leather and metal: ** more expensive, imitation leather and leather surface is easy to scratch and can not be repaired, the thickness of the metal, the surface coating is easy to wear and not easy to repair.

Note: Do not wash with strong acids.

Do not wash with hard substances.

1) First of all, you can try to clean its shell with toothpaste, be gentle, provided that the phone case is yellowed because the skin is not clean. Squeeze toothpaste on the surface of the case, smear it with your hands and clean the surface of the case, if there is some dirt, you can rub it with the wire we use to wash dishes.

2) Take a look at the comparison in the picture below, although the phone case is still a little yellow after rubbing, the oil stains on it have been cleaned, indicating that the yellowing is due to oxidation. What the??? Still dirty on the edges? If you are too lazy to get toothpaste, you can also use an eraser to wipe the edges.

3) If you don't have the above things, you can also use soap instead of toothpaste and alcohol instead of eraser. Soap is just the right thing to remove oil.

4) If you stain the phone case because of coffee, tea, cocoa and other drinks, you can also use bleach to clean it, but bleach has a chemical taste, if you use bleach you can ventilate the phone case.

5) After the above steps, the phone case will become very clean.

1. Use digital cleaner to clean. Spray the cleaning solution onto a clean cloth and wipe down the phone case.

2. Wash with water, soak in clean water for 1 hour, rub it and wipe it clean with wet wipes.

3. If it is just a small stain that is a little dirty, apply it with soap and rinse it with water to make it clean.

4. Eraser. The eraser's stain removal ability is also very strong, you can hold the eraser and wipe the dirty area vigorously, and the effect is still obvious.

The methods of cleaning dirty phone cases are: toothpaste + salt washing, toothpaste + toilet washing.

1. Toothpaste + salt washing: first squeeze the toothpaste on the mobile phone case, and then brush it with a toothbrush, do not get wet during the brushing process, just brush the inside and outside of the mobile phone case, and then sprinkle a layer of salt to continue to scrub, and finally wash it with water, and the mobile phone case can be restored to new after a while.

2. Toothpaste + toilet wash: Squeeze toothpaste and toilet water on the yellowed mobile phone case, and evenly apply it to the mobile phone case. After applying the letter evenly, set the phone case aside and let it sit for 10 minutes to penetrate the stain.

After the stain is penetrated, wash it with clean water and wipe it dry to wash and turn white.

Reasons why the phone case turns yellow

1. The influence of the polymer structure itself: there is bond energy between the bonds of the polymer macromolecular chain, and when the energy provided is greater than the bond energy, the molecular chain is easy to produce active concentration, which will gradually degrade the polymer in the process of use and storage, resulting in yellowing.

2. The influence of oxygen molecules: the oxidation reaction of the applied material will occur over time, and the heat will accelerate the oxidation process of the material. After the peroxide structure is formed, free radicals are easily formed, resulting in discoloration of transparent, light-colored, and white materials.

3. The influence of other factors: yellowing is also related to the additives added to the application materials, the presence of moisture, impurities and processing and production technology. Raw materials mixed with various chemical or mechanical impurities can reduce the stability of the polymer.

The cause is complex and needs to be analyzed and troubled.
