Have you ever wondered why your once-pristine white keyboard starts to turn yellow after a few months of use? It’s a phenomenon that has plagued keyboard enthusiasts and office workers alike, leaving many of us wondering what causes this unsightly discoloration. In this article, we’ll delve into the science behind why white keyboards turn yellow, and what you can do to prevent or reverse this process.
The Science of Yellowing: What Causes it?
The process of yellowing is a complex one, involving a combination of chemical reactions and environmental factors. One of the primary culprits behind yellowing keyboards is a phenomenon known as photodegradation.
Photodegradation: The Breakdown of Plastics
Photodegradation occurs when plastics, such as those used in keyboard construction, are exposed to light – particularly ultraviolet (UV) light. This exposure causes the molecular bonds in the plastic to break down, leading to a change in color. In the case of white keyboards, this breakdown can cause the plastic to take on a yellowish hue.
But photodegradation isn’t the only factor at play. Another key contributor to yellowing keyboards is the buildup of contaminants.
Contaminants: The Unwelcome Guests
Contaminants, such as dirt, dust, and oils from your skin, can accumulate on the surface of your keyboard over time. As these substances build up, they can react with the plastic to cause discoloration. The combination of photodegradation and contaminant buildup can create the perfect storm for yellowing.
Other Factors that Contribute to Yellowing
In addition to photodegradation and contaminants, there are several other factors that can contribute to the yellowing of white keyboards.
Aging and Oxidation
As plastics age, they undergo a process called oxidation. This process causes the plastic to break down, leading to a change in color. Over time, this oxidation can cause the keyboard to take on a yellowish tint.
Pigment Migration
Some keyboards use a process called pigment migration to achieve their white color. In this process, the pigments used to create the white color can migrate to the surface of the plastic over time, causing discoloration.
Exposure to Chemicals
If you work with chemicals or cleaners that contain strong solvents, you may be exposing your keyboard to substances that can cause discoloration. Some chemicals can break down the plastic, leading to a yellowish color.
How to Prevent Yellowing: Tips and Tricks
Now that we’ve explored the science behind yellowing keyboards, let’s take a look at some tips and tricks for preventing this phenomenon.
Keep it Clean
One of the simplest ways to prevent yellowing is to keep your keyboard clean. Regularly wipe down your keyboard with a soft cloth and gentle cleaning solution to remove dirt and contaminants.
