Tired of seeing your clear silicone cases turn yellow? If yes, you are in the right place. No matter how much you take care of a clear silicone case, it faces discoloration. The discolored phone case ruins the beauty of your phone.

Silicone cases turn yellow due to oxidation from ultraviolet radiations, excess heat, and natural oils and sweat from your hands. It is an irreversible process because the silicone cases are naturally yellow. The yellowness only increases with time due to the environment.

Reasons Why Silicone Cases Turn Yellow

Here’s the thing:

Silicone phone cases naturally have a yellow hue in them. The yellowness only increases with time.

Silicone is an expensive material that provides flexibility to the phone case. It serves as a suitable material for manufacturing phone cases. But one disadvantage of silicone is its oxidation which makes it yellow.

Every silicon phone case undergoes the yellowing procedure. However, certain factors accelerate the yellowing of silicone phone cases. If you know these factors, you can prevent the yellowing of the silicone case for a long time. So, learn about all the factors!

Ultraviolet (UV) Radiation

UV radiations are the main culprit in accelerating the aging process of silicone cases. If you stay outdoors a lot and your phone case is exposed to sunlight, it will age faster. 

Sunlight consists of excess heat and light, especially in summer. Both these contribute to the yellowing of silicone cases. 

UV rays cause the oxidation of silicone after which it changes its color and turns yellow. So, the more the silicone case is exposed to extreme sunlight, the more it turns yellow.

Sweat and Oil From Hands

Your phone case comes in contact with your hands all the time. Your hands release natural oils and sweat from glands. Both of these contribute to the acceleration of the degradation of silicone cases.

All the chemicals from your hands build up on the phone case turning it yellow.

Also, imagine it this way. You eat something greasy and get a text from someone. You take your phone without cleaning your hands. The grease from your hand transfers to the phone case. That is also another factor that makes the silicon case yellow.

Your hands also provide heat to the phone case. When you use your phone for hours, the heat develops to a considerable amount. It degrades the silicone cases as well.
