Your laptop keyboard is one of the most frequently used parts of your computer—and also one of the dirtiest. Every day, it collects dust, food crumbs, skin oils, and bacteria. Over time, this buildup can cause keys to stick, stop working, or even lead to hygiene issues.
Cleaning your laptop keyboard regularly not only keeps it looking good but also improves performance and extends its lifespan. The good news is that you don’t need professional tools or technical skills to do it safely.
In this guide, you’ll learn how to clean your laptop keyboard properly, what tools to use, what to avoid, and how often you should clean it.
