In our daily work and study, especially in office settings or classrooms, whiteboard markers are commonly used. A smooth-writing whiteboard pen can greatly enhance the teaching experience and make presentations more effective. However, during regular use, it's not uncommon to encounter a situation where the marker runs out of ink or becomes completely dry. So, what should you do if your whiteboard pen is dry? Let’s explore some practical solutions below.
First, understand how whiteboard pens work
When people face the issue of a dry whiteboard pen, one common reaction is to simply throw it away and get a new one. While this might seem like an easy fix, it’s actually a waste of resources. Instead, it’s better to learn a bit about how these pens function so you can address the problem more effectively.
Whiteboard pens are designed to write on smooth whiteboards, much like chalk does on a blackboard. They use liquid ink that glides smoothly across the surface and can be easily erased with a whiteboard eraser or even your finger if you don’t have one handy. The ink is usually water-based and evaporates quickly, which is why it’s important to keep the pen sealed when not in use.
Second, the composition of the ink
The ink inside a whiteboard pen typically contains ingredients such as ethylene glycol, ethanol, and carbon black. These components play a crucial role in how the pen performs. Ethanol and other alcohols are volatile, meaning they evaporate over time. If the alcohol dries up, the ink becomes too thick or stops flowing altogether, making it difficult to write. This is the main reason why a whiteboard pen may stop working when it's dry.
Additionally, the amount of carbon black in the ink affects the visibility of the writing. If there's not enough, the text will appear faint and hard to read. On the other hand, if there's too much, it might leave behind a residue on the whiteboard, which can be hard to clean and affect future use.
Third, the solution
The most straightforward way to revive a dry whiteboard pen is to refill it with the appropriate ink. If you don't have the exact ink, adding a small amount of rubbing alcohol (like isopropyl alcohol) can sometimes help restore its functionality. Be careful not to overfill the pen, and always make sure to close the cap tightly after use to prevent further evaporation.
By understanding how whiteboard pens work and knowing how to properly maintain them, you can extend their lifespan and save money in the long run. Next time your whiteboard pen dries up, you’ll know exactly what to do—no need to throw it away just yet!
