Your laptop keyboard is a breeding ground for bacteria and grime. From crumbs and dust to sticky spills and hair, it’s a daily battle against the elements. A dirty keyboard not only looks unsightly but can also hinder your typing accuracy and even damage your laptop. Thankfully, a deep clean is an achievable task that can restore your keyboard to pristine condition.

This comprehensive guide will walk you through the entire process, from gathering the right tools to cleaning each component carefully. By following these steps, you’ll have a sparkling clean keyboard that feels good to type on and is free of harmful bacteria.

Step 5: Deep Cleaning with Cotton Swabs

  • Cotton Swabs and Alcohol: For deep cleaning, dip a cotton swab into the alcohol solution.
  • Reach into Tight Spaces: Carefully insert the swab into the crevices around and under the keys to remove any remaining grime.
  • Clean Keycaps: If necessary, use a cotton swab to gently clean the underside of each keycap.

Step 6: Remove Stubborn Dirt and Debris

  • Keys Not Working: If a key isn’t working, it could be a result of a stuck or damaged switch. You can try cleaning the key with a cotton swab and alcohol solution. If that doesn’t solve the issue, it may require professional repair.
  • Water Damage: If your keyboard has been exposed to water, immediately power off your laptop and unplug it. Avoid turning it on until it has completely dried. It’s best to take it to a professional for repair if the damage is extensive.


Keeping your laptop keyboard clean is crucial for maintaining its functionality, improving your typing experience, and protecting your health. By following these steps, you can effectively deep clean your keyboard, removing dirt, debris, and germs. Remember to perform regular maintenance, avoid spills, and address any issues promptly to ensure your keyboard stays clean and functional for years to come.


1. How often should I deep clean my laptop keyboard?

It’s recommended to deep clean your laptop keyboard at least once a month, or more frequently if you use it heavily or in dusty environments. However, regular maintenance, such as wiping the keys with a microfiber cloth, should be done more often to prevent dirt buildup. Regular cleaning can prevent the accumulation of dirt, crumbs, and grime that can affect the functionality and lifespan of your keyboard.

2. What tools do I need for deep cleaning my laptop keyboard?

You’ll need a few basic tools for deep cleaning: a microfiber cloth, a can of compressed air, a small, soft-bristled brush, isopropyl alcohol (70% solution), cotton swabs, a small bowl, and a vacuum cleaner with a crevice attachment. These tools will help you effectively remove dirt, dust, and debris from the crevices and gaps of your keyboard.

3. Can I use water to clean my laptop keyboard?

Using water directly on your laptop keyboard is generally not recommended. Water can damage the delicate internal components of your laptop, such as the circuit board. If you accidentally spill water on your keyboard, immediately unplug the laptop, dry it thoroughly with a towel, and allow it to air dry completely before turning it back on.

4. What should I do with sticky keys?

Sticky keys can be frustrating and hinder your typing experience. To clean sticky keys, use a cotton swab dipped in isopropyl alcohol (70% solution) to gently rub the key caps. Avoid soaking the keys in alcohol, as it can seep into the keyboard and cause damage. After cleaning, allow the keys to air dry completely before using the keyboard again.

5. Can I use a vacuum cleaner to clean my laptop keyboard?

Using a vacuum cleaner with a crevice attachment can be helpful for removing larger debris, such as crumbs, from your keyboard. However, avoid using a vacuum cleaner with a powerful suction setting, as it can damage the keys and internal components of the keyboard. Use a gentle suction setting and hold the vacuum cleaner a safe distance away from the keyboard.

6. Can I use a keyboard cleaner spray?

Keyboard cleaner sprays are available, but it’s essential to use them with caution. Ensure the spray is specifically designed for electronics and avoid spraying directly onto the keyboard. Instead, spray the cleaning solution onto a microfiber cloth and gently wipe the keys. Allow the keys to air dry completely before using the keyboard.

7. How do I keep my laptop keyboard clean in the long run?

Regular maintenance is crucial for keeping your laptop keyboard clean and functional. Avoid eating and drinking near your laptop, use a keyboard cover when not in use, and wipe the keys regularly with a microfiber cloth. This will help to prevent dirt, dust, and grime from accumulating and extending the lifespan of your keyboard.
