Why is my phone case turning yellow?

Clear Case Turned Yellow - Can You Clean It?

Today, we're diving into a common woe among smartphone users: your clear cases has turned yellow over time. If you've ever experienced this frustration, you're not alone. In this blog, we'll explore why this phenomenon occurs, discuss prevention methods, and address the burning question: Can you clean a yellowed clear case?

Understanding Material Degradation

The yellowing of clear cases is a result of material degradation. Over time, the molecular structure of the case changes, leading to a yellow tint. This degradation is primarily influenced by two factors: sunlight and heat.

Sunlight and Heat: Culprits of Yellowing

Sunlight, with its ultraviolet radiation, accelerates the degradation process. Likewise, heat also plays a significant role, speeding up the yellowing of the case. While these factors are natural and often unavoidable, minimizing exposure to sunlight and heat can help slow down the yellowing process.

Quality Matters

The type of material used in clear cases also affects their susceptibility to yellowing. Cheaper silicon cases, characterized by their rubbery and flexible texture, are more prone to yellowing compared to high-quality polycarbonate cases like those made by Apple. Investing in a durable, high-quality case can significantly extend its lifespan without succumbing to yellowing.

Can You Clean a Yellowed Clear Case?

Common home cleaning products; Baking Soda, Vinegar, Dishwashing Liquid

Unfortunately, the answer is no. Despite various methods like baking soda, dish soap, and rubbing alcohol, the yellowing is not due to dirt or stains but rather a fundamental change in the plastic's molecular structure. No amount of cleaning can reverse this process.

What You Can Do

If you're partial to clear cases, there are a few options to consider:

  1. Invest in Quality: Opt for high-quality clear cases made from durable materials like polycarbonate to minimize yellowing and increase longevity.

  2. Limit Exposure: Reduce exposure to sunlight and heat to slow down the yellowing process.

  3. Replace Regularly: If you prefer cheaper clear cases, be prepared to replace them every few months to maintain a clear appearance.

The yellowing of clear cases is an unfortunate but inevitable reality for many smartphone users. While prevention methods can help slow down the process, cleaning a yellowed case is simply not feasible. By understanding the causes and investing in quality cases, you can ensure your device stays protected and aesthetically pleasing for longer.

So, next time you're in the market for a clear case, remember to prioritize quality over price to avoid the yellowing headache down the line. Until next time, stay tuned for more tech insights from Tinker Mobile!
