How to clean a Mac keyboard

A Clean Mac keyboard is essential for good functionality and hygiene. Over time, dust, crumbs, and other debris can accumulate between the keys, which can lead to sticky or unresponsive keys, or even more severe issues if not addressed properly. Here’s a comprehensive guide on how to clean your Mac keyboard effectively.

Understanding the Need for Cleaning

The keyboard is one of the most touched components of your Mac, making it a magnet for dirt, dust, and bacteria. Regular cleaning helps in:

Improving Performance: Dust and debris can cause keys to become sticky or unresponsive. Cleaning ensures that your keyboard works smoothly.
Hygiene: Keyboards can harbor germs and bacteria, especially if you eat while working. Cleaning reduces the risk of illness.
Aesthetic Appeal: A clean keyboard enhances the overall look of your Mac, making it look well-maintained.

Precautions Before Cleaning

Before you start cleaning, it’s essential to take a few precautions to avoid damaging your keyboard or the Mac itself.

Turn Off the Mac: Always turn off your Mac and unplug it from any power source to prevent electrical damage.
Remove External Devices: Disconnect any external devices, including USB drives or headphones, to avoid accidental damage.
Use the Right Tools: Ensure you have the appropriate cleaning tools like a microfiber cloth, compressed air, isopropyl alcohol (70% or higher), and a soft brush. Avoid using excessive liquid or harsh chemicals.

Steps to Clean Mac Keyboard

1. Surface Cleaning

Start with surface cleaning to remove the dust and dirt on top of the keys.

Use a Microfiber Cloth: Gently wipe the surface of the keyboard with a dry microfiber cloth. This cloth is ideal because it doesn’t leave lint behind and is soft enough not to scratch the surface.
Compressed Air: Hold the can of compressed air upright and blow between the keys to dislodge any dust or small particles. Make sure to use short bursts and keep the can at a safe distance to avoid moisture from the air canister damaging the keyboard.
Brush: Use a soft brush to gently clean between the keys. This helps to remove any particles that the compressed air may have missed.

2. Deep Cleaning for Stubborn Dirt

For more stubborn dirt and grime that has accumulated over time, a deeper cleaning approach is necessary.

Isopropyl Alcohol: Dampen a corner of a microfiber cloth with isopropyl alcohol (70% or higher). Do not pour the alcohol directly on the keyboard. Gently wipe the keyboard’s surface with a dry microfiber cloth. The alcohol helps to dissolve any sticky residues and evaporates quickly, reducing the risk of moisture damage.
Cotton Swabs: For the areas between the keys, a cotton swab dipped in isopropyl alcohol can be used. Be gentle to avoid pressing too hard, which could dislodge the keys or push debris further into the keyboard.

3. Cleaning Under the Keys

If you feel comfortable and your keyboard is particularly dirty, you may need to clean underneath the keys. This step is more advanced and should be done with care to avoid damaging the keyboard.

Removing the Keys: For most Mac keyboards, you can gently pry off the keys using a flat tool like a small screwdriver or a plastic opening tool. Insert that tool under the keycap and gently lift it. Be cautious as the keys are delicate and the clips holding them can break easily.
Cleaning Underneath: Once the keycaps are removed, use a soft brush or compressed air to clean the area underneath. If there is any sticky residue, use a cotton swab with isopropyl alcohol to clean it.
Reattaching the Keys: After cleaning, carefully place the keycap back on its corresponding switch and press down gently until it snaps back into place. Make sure the key is aligned properly before pressing it down to avoid damaging the switch.

4. Disinfecting

To ensure your keyboard is not only clean but also free from germs and bacteria, disinfecting is crucial, especially during flu seasons or after someone else has used your keyboard.

Disinfecting Wipes: Use disinfecting wipes that are safe for electronics. Wipe down the entire keyboard, paying particular attention to the most frequently used keys (like the spacebar, return key, and arrow keys). Ensure the wipe is not too wet to avoid moisture getting into the keyboard.
Isopropyl Alcohol: If you don’t have disinfecting wipes, you can use a microfiber cloth lightly dampened with isopropyl alcohol to disinfect the keys.

Tips Maintain a Clean Keyboard

Regular Cleaning: Make it a habit to clean your keyboard regularly. Even a quick wipe-down once a week can prevent the build-up of dirt and grime.
Avoid Eating Over the Keyboard: Crumbs and food particles are common culprits for dirty keyboards. Try to avoid eating directly over your keyboard.
Wash Your Hands: Washing your hands before using your Mac can significantly reduce the amount of oil, dirt, and bacteria that ends up on your keyboard.
Keyboard Cover: Consider using a keyboard cover. These thin, transparent covers protect your keyboard from dirt and spills without affecting your typing experience.
Proper Storage: When not in use, consider covering your keyboard with a dust cover or storing your Mac in a case to prevent dust accumulation.

Troubleshooting Common Issues

Even with regular cleaning, you might encounter some issues with your keyboard. Here is how to address some common problems:

Stuck Keys: If a key feels stuck even after cleaning, there might be something lodged underneath. Try removing the keycap and cleaning the area again. If this problem persists, consider seeking professional help.
Unresponsive Keys: If some keys are not responding, there might be debris blocking the key switch or a more serious issue like liquid damage. After cleaning, if the problem remains, you might need to take your Mac to an authorized service provider.
Spills: If you accidentally spill liquid on your keyboard, immediately turn off your Mac and disconnect it from any power source. Place the Mac upside down to allow the liquid to drain out and leave it to dry for at least 24 hours. Do not attempt to turn it on until you are sure it is completely dry. Depending on the extent of the spill, you may need to seek professional repair.

Conclusion

Keeping your Mac keyboard clean is not just about aesthetics; it’s about maintaining functionality and hygiene. By following the steps outlined above, you can keep your keyboard in top condition, ensuring it remains responsive and pleasant to use. Regular cleaning, combined with preventive measures, will help extend the lifespan of your keyboard and improve your overall computing experience.

Remember, while some cleaning tasks can be done at home, don’t hesitate to seek professional help if you encounter any difficulties or if you are unsure about removing keycaps or dealing with spills. A clean keyboard is a happy keyboard, and with the right care, your Mac will serve you well for years to come.
