Frequent use of your keyboard and mouse can result in a buildup of dirt, oil, and germs. This can lead to illness-causing bacteria and even malfunction of your devices. To avoid this, follow our easy cleaning tips to keep your keyboard and mouse clean and germ-free.

Input devices such as keyboards and mice are essential to using a computer. They are also the parts that show the most wear and tear due to frequent use. As we use our hands to operate these devices, they become a breeding ground for dirt, oil, and germs. This problem can be even worse if you share your computer or use public computers.

Research shows that keyboards can be dirtier than toilet seats. A study conducted by British microbiologist James Francis found harmful bacteria on four out of thirty keyboards, with one having germs five times higher than a toilet seat. Another study showed that a keyboard shared by first-grade students had a virus linked to stomach flu.

In addition to harmful germs, debris such as crumbs, fluids, pet hair, and dust can accumulate under and between keys. This can cause sticky or malfunctioning keys, affecting the device’s performance. Therefore, it is important to regularly clean your keyboard and mouse.

This article provides tips on cleaning your keyboard and mouse to prevent germ buildup and device malfunction.
