Modern smartphones, especially the latest iPhone models, are marvels of design, featuring stunning finishes and sleek profiles that you don’t want to hide. A clear phone cover is the perfect solution, offering essential protection while allowing the original aesthetic of your device to shine through. However, many users face a common and frustrating problem: the crystal-clear case gradually turns a dingy yellow. This guide will walk you through how to clean your case and, more importantly, how to prevent it from yellowing in the first place.
Understanding Why Clear Cases Turn Yellow
Before diving into cleaning methods, it’s helpful to understand why this happens. The yellowing of a clear phone case isn’t usually due to dirt or grime. Instead, it’s a natural chemical reaction. Most flexible clear cases are made from a polymer called Thermoplastic Polyurethane (TPU). When this material is exposed to ultraviolet (UV) radiation from the sun, as well as heat and oils from your hands, the polymer chains begin to break down. This degradation process, known as photo-oxidation, results in that undesirable yellow tint. While you can’t completely stop this natural aging process, you can certainly slow it down and clean away any surface-level contributors.
A Step-by-Step Guide to Cleaning Your Clear Case
If your case has already started to show signs of yellowing, a thorough cleaning can help restore some of its clarity. Here are a few methods to try, from gentle to more intensive. Start by removing the case from your phone. 1. The Soap and Water Method: For regular maintenance or light discoloration, this is your best bet. Mix a few drops of mild dish soap into a bowl of warm water. Submerge the case and use a soft-bristled brush, like an old toothbrush, to gently scrub all surfaces, paying special attention to corners and edges. Rinse the case thoroughly with cool water and dry it completely with a soft, lint-free cloth before putting it back on your phone.2. The Baking Soda Paste Method: For more stubborn yellowing, baking soda can act as a mild abrasive to lift surface stains. Create a paste by mixing baking soda with a small amount of water. Apply this paste all over your clear phone case for iPhone, focusing on the most discolored areas. Let the paste sit for 20-30 minutes, then gently scrub it with your soft brush. Rinse it completely and dry thoroughly.
Proactive Care: How to Prevent Yellowing
Prevention is always better than a cure. To keep your clear phone cover looking pristine for as long as possible, incorporate these habits into your routine.- Regular Cleaning: Make it a weekly habit to wipe down your case with the soap and water method described above. This removes the oils, sweat, and dirt that can accelerate the yellowing process.- Avoid Direct Sunlight: Since UV radiation is the main culprit, be mindful of where you leave your phone. Avoid leaving it on a car dashboard, a sunny windowsill, or out in direct sun for extended periods.- Handle with Clean Hands: The natural oils and lotions on your skin can contribute to discoloration over time. Washing your hands before extended phone use can make a surprising difference.- Avoid Harsh Chemicals: Never use harsh chemicals like bleach, acetone, or abrasive cleaners on your case, as they can permanently damage the material and make it more prone to yellowing.
Choosing the Right Anti-Yellowing Case
When it’s time for a new case, make a smart purchase. Not all clear cases are created equal. Look for a clear phone case for iPhone that is specifically marketed with “anti-yellowing” properties or a “blue resin” infusion. These cases are often made from higher-grade polymers or have a special protective coating that significantly resists UV degradation. Cases made with a hard polycarbonate (PC) back and TPU sides also tend to fare better, as PC is naturally more resistant to yellowing than TPU. Investing a little more in a quality case can save you the frustration of dealing with a yellowed one later on.
