How to Clean a Laptop Keyboard?

Maintaining the lifespan and performance of your laptop involves frequent cleaning of its keyboard. Over time, debris such as dust and crumbs can accumulate which can compromise the efficiency of typing and may even damage the keyboard. This comprehensive guide provides thorough, step-by-step guidance on the correct way to clean your laptop keyboard.

1. Gather the Necessary Supplies

Before you begin the cleaning process, gather the following supplies:

  • Isopropyl alcohol or electronic cleaning solution: This will be used to clean the keys and remove any stains or stickiness.
  • Cotton swabs: These are ideal for reaching between the keys and cleaning hard-to-reach areas.
  • Microfiber cloth: Use this to wipe down the keys and remove any remaining debris or residue.
  • Compressed air canister: This will help dislodge dust and crumbs from the keyboard.

2. Shut Down and Unplug Your Laptop

To ensure your safety and prevent any potential damage to the hardware, it is important to shut down your laptop completely and unplug it from the power source.

3. Turn the Laptop Upside Down

To remove loose debris and dust, turn your laptop upside down and gently tap the back to dislodge any particles that may have fallen between the keys. By doing this, you will make it easier to clean the keyboard thoroughly.

4. Use Compressed Air

Next, take your compressed air canister and hold it upright. Use short bursts of air to blow away any remaining dust or debris from the keyboard. Start from one end and work your way across the entire keyboard, paying close attention to each key.

5. Clean the Keys

Now it’s time to clean the keys themselves. Dip a cotton swab into the isopropyl alcohol or electronic cleaning solution. Make sure the swab is not dripping wet, as excessive liquid could damage the keyboard. Gently rub the swab over each key in a circular motion, paying extra attention to any sticky or soiled keys.

6. Focus on Problematic Areas

If certain keys are particularly dirty or sticky, you may need to remove them for a more thorough cleaning. To do this, gently pry the keycap using a plastic tool or your fingernail. Be careful not to exert too much force, as this can cause damage.

Once the keycap is removed, clean it separately using the same method as described in step 5. Additionally, clean the area underneath the keycap using a cotton swab or compressed air to remove any debris.

7. Wipe Down the Keyboard

After cleaning the keys, take a microfiber cloth and gently wipe down the entire keyboard surface. This will remove any remaining residues and give your laptop keyboard a polished finish.

8. Allow the Keyboard to Dry

Once you have completed the cleaning process, it is crucial to let the keyboard dry completely before turning your laptop back on. This will prevent any potential damage that could occur from moisture.

9. Test the Keys

Before considering the cleaning process complete, test each key to ensure it is functioning properly. Press each key individually and check for any sticking, unusual noise, or unresponsiveness. If you notice any issues, repeat the cleaning process for the problematic key.


Regularly cleaning your laptop keyboard is essential for maintaining its performance and longevity. By following the step-by-step instructions provided in this article, you can effectively clean your laptop keyboard and keep it in optimal condition. Remember to gather the necessary supplies, shut down and unplug your laptop, use compressed air, clean the keys, wipe down the keyboard, and allow it to dry before testing the keys. With proper care and maintenance, your laptop keyboard will continue to serve you well for years to come.
