How to Clean a Clear Phone Case (4 Essential Methods)


Phone cases are more than just protective gear for your smartphones; they're a style statement. But with regular use, even the clearest of cases can lose their lustre, becoming grimy or yellowed. In this blog post, we'll guide you through the best methods to clean your clear phone cases, keeping them looking fresh and new.

The Science Behind the Yellowing

  • Material Composition: Clear phone cases are often made from polymers like silicone, polycarbonate, or TPU (thermoplastic polyurethane). These materials are chosen for their flexibility and durability, but they have a downside.
  • Photo-Oxidation: When exposed to sunlight and UV rays, a process called photo-oxidation occurs in these materials. UV exposure triggers a chemical reaction in the polymers, leading to a change in colour, usually turning them yellow. This process is similar to how certain plastics or fabrics can fade or discolour when left in the sun for too long​​​​.
  • Natural Aging: Besides UV exposure, yellowing is a part of the natural ageing process of these materials. Over time, the polymers undergo degradation, which contributes to the yellowing effect.
  • External Factors: Everyday factors like the oils from your hands, exposure to heat, and contact with certain chemicals can accelerate this yellowing process. Regular cleaning can reduce this effect, but it cannot completely prevent the material from yellowing over time.

For a Natural Cleaning Solution

Method: Use lemon juice for natural stain removal.


  1. Squeeze fresh lemon juice into a small bowl. For tougher stains, you can mix the lemon juice with a small amount of water to dilute it slightly.
  2. Dip an old toothbrush or a soft cloth into the lemon juice. Apply it directly to the stained areas of the phone case. Lemon juice is particularly effective on discolouration and can help lighten stains.
  3. Gently but firmly scrub the stained areas with the toothbrush or cloth. The natural acidity of the lemon juice helps break down the stains without damaging the case material.
  4. For deep-set stains, let the lemon juice sit on the case for a few minutes to penetrate and lift the stains.
  5. Rinse the phone case under running water to remove all traces of lemon juice, ensuring that no sticky residue is left behind.
  6. Pat the case dry with a clean cloth, or let it air dry completely before putting it back on your phone.

Step 3: Rinse and Dry

After cleaning, rinse the case thoroughly under running water. Dry it completely with a lint-free cloth or let it air dry.

Things to Remember NOT to Do When Cleaning Phone Cases

While cleaning your phone case is essential for maintaining its appearance and hygiene, there are certain practices you should avoid to prevent damage. Here are some key things to remember:

Avoid Harsh Chemicals

  • Steer clear of using harsh cleaning agents like bleach or ammonia-based cleaners. These can deteriorate the materials of your phone case, leading to discolouration and weakening of the case.

Do Not Soak in Water

  • While it's okay to rinse your phone case, avoid soaking it in water for an extended period. Prolonged exposure to water can harm the material, especially if your case has any decorative elements or is made of sensitive materials.

Avoid Excessive Heat

  • Do not use heat sources like hair dryers to speed up the drying process. High temperatures can warp or melt certain types of phone case materials.

Don’t Scrub Aggressively

  • While using a toothbrush or cloth to clean your case, be gentle. Vigorous scrubbing can cause scratches and remove any protective coatings on the case.

Be Cautious with UV Sanitizers

  • UV sanitizers are great for killing germs, but make sure your phone case material is compatible. Some materials may be sensitive to UV exposure and can degrade over time.

Don't Ignore the Manufacturer’s Instructions

  • Always check the cleaning recommendations provided by the manufacturer. Different materials may require specific care instructions to avoid damage.

By avoiding these common mistakes, you can ensure that your phone case stays in top condition for longer. Remember, the goal is to clean effectively while preserving the integrity and appearance of your phone case.

Tips for Maintaining a Clear Phone Case

Regular Cleaning

  • Why It's Important: Dirt, oils, and other residues from daily use can accumulate on your phone case, leading to a buildup that not only looks unsightly but can also harbor bacteria.
  • Best Practices: Clean your case regularly, ideally once a week, using a gentle soap and water solution. For a more thorough clean, especially if your case starts to look cloudy or feel sticky, use a soft-bristled brush to gently scrub the case.

Avoid Direct Sunlight

  • Impact of Sunlight: Just like how sunlight can damage your skin, it can also affect the materials of your phone case. Prolonged exposure to UV rays can accelerate the yellowing process, especially in cases made from silicone or plastic.
  • Preventive Measures: Try to keep your phone out of direct sunlight as much as possible. When you're not using it, store it in a shaded place. If you often leave your phone in places like a car dashboard, consider getting a UV-protective cover or a case with UV-resistant properties.

Use Gentle Cleaning Agents

  • Dangers of Harsh Chemicals: Harsh chemicals, such as bleach or ammonia, can damage the material of your phone case. They can cause the plastic to break down, become brittle, or discolour quickly.
  • Safe Alternatives: Stick to mild detergents or homemade cleaners like a mix of water and vinegar. If you choose to use specialized cleaning products, ensure they are suitable for the type of material your phone case is made of. Always read the label for any specific instructions or warnings.

By adhering to these tips, you can keep your clear phone case looking as good as new. It's all about regular care and being mindful of the environmental factors that can affect your case's appearance.
