Phone cases are used to protect your beloved device, with a variety of materials to choose from, such as plastic, hard plastic, and metal. However, the softer, more flexible cases tend to discolor and turn yellow over time.

To help you get a brand-new-looking case without spending extra money, let’s explore 6 ways to whiten and brighten your old phone case!

Reasons for Discoloration

Most flexible phone cases on the market are made from Thermoplastic Polyurethane, also known as TPU, which creates a durable, flexible, and highly versatile case. However, with prolonged use, many cases start to discolor and turn yellow due to exposure to sunlight, heat, humidity, and even your skin’s natural oils.

It’s important to note that while the discoloration doesn’t affect the functionality of the case, it does impact its aesthetics. Additionally, the stains on TPU cases are caused by chemical reactions and usually won’t disappear without external intervention.

6 Whitening Methods for Phone Cases

1 Use Vim Solution

This is one of the most effective ways to remove yellow stains from your phone case. Simply apply the solution evenly over the case for 15-20 minutes, then rinse it off thoroughly with water to restore its original color.

Remember to wear gloves when using Vim solution, as it has a similar chemical composition to super glue (“keo dán 502” in Vietnamese) and can be harmful to your skin if direct contact occurs.

2 Use Dish Soap

Dish soap is a readily available kitchen staple that can work wonders. Simply dilute a small amount of dish soap and use it to scrub the case thoroughly, paying attention to all the nooks and crannies. This will effectively remove any stains.

3 Use Baking Soda

Baking soda is a “miracle worker” and one of the most effective methods for whitening almost anything. You can easily find it in supermarkets and grocery stores.

Take a small amount of baking soda and mix it with a little water to form a thick paste. Add a few drops of lemon juice to enhance its brightening effect. Apply the mixture evenly to your phone case and let it sit overnight until it’s completely dry. Then, rinse it off with clean water, and you’re done!

4 Use Borax

Borax, also known as “hàn the” in Vietnamese, is another great option for whitening your phone case. Combine it with dish soap to optimize its cleaning power.

After diluting the mixture in a bowl of water, soak your phone case in the solution for 1-2 hours, then scrub and rinse it with clean water. Your case will look as good as new!

Note: You can purchase borax at any chemical supply store.

5 Use Isopropyl Alcohol (Cồn IPA)

This is an extremely potent and effective method for stubborn, hard-to-remove stains. If regular dish soap doesn’t work, try wiping the stained area with isopropyl alcohol a few times.

Isopropyl alcohol is a commonly used solvent in the cosmetics and fragrance industries and can be purchased at chemical supply stores or pharmacies.

6 Use Vinegar, Lemon, or Soapnut Solution

You can easily clean your phone case with typical household cleaning agents such as vinegar, lemon, or soapnut.

Mix lemon or vinegar with a small amount of water, preferably in a 1:2 ratio, and use a soft cloth to scrub the mixture onto the case vigorously. After scrubbing, let the case soak for 10-15 minutes before rinsing it with clean water to improve its appearance.
