1. Why is the phone case yellow?
Most of the flexible cases on the market are made from Thermoplastic Polyurethane (TPU). TPU is a material known for its durability, flexibility, and flexibility in creating phone cases. However, over time, these cases may start to turn yellow due to exposure to the sun, heat, moisture, and sweat from your skin. While these yellow stains do not affect the protective function of the phone case, they can be unsightly.
2. Tips for bleaching yellowed phone cases
Use dishwashing liquid
An easy and effective method is to use diluted dishwashing liquid. Apply the dishwashing liquid on the surface of the case and scrub it using a toothbrush to remove the yellow stains.
Use isopropyl alcohol
For heavier stains that cannot be removed with dishwashing liquid, isopropyl alcohol can be used. Apply the isopropyl alcohol on the surface of the stain to effectively remove it.
Use soldering iron
Another option is to combine solder paste with dishwashing liquid. Dilute the mixture in a basin of water, soak the case in the mixture for 1-2 hours, and scrub it with clean water to significantly improve the yellow stains.
Using Baking Soda
Baking soda can be mixed with water to form a thick paste. Apply the paste on the phone case, leave it overnight to dry, and then rinse with clean water.
Use Vim solution
Vim cleaning solution can be applied on the surface of the case for 15-20 minutes and then rinsed thoroughly with water to improve its condition. However, precautions should be taken when using Vim as it can have adverse effects on the body.
Use natural solutions
Natural solutions like vinegar, lemon, and soap can also be used to clean the case. Mix these solutions with water to form a thick mixture, rub it on the case using a soft cloth, let it soak for 10-15 minutes, and then rinse with clean water.
With these simple methods, you can restore your yellowed flexible phone case to its original condition. Try them out and enjoy the results!
