Why You Should Clean Your Keyboard Regularly
A computer keyboard is often one of the most frequently touched surfaces in a home or office, yet it’s commonly overlooked during regular cleaning. Consistent cleaning is crucial for several reasons, impacting hygiene, performance, and the device’s overall lifespan.
Hygiene and Health
Keyboards can harbor a significant amount of bacteria, germs, and viruses. Skin cells, oils from your fingers, food particles, and dust create a breeding ground for microorganisms. Regularly disinfecting your keyboard helps reduce the spread of germs and can contribute to a healthier workspace, minimizing the risk of illness.
Performance and Functionality
Over time, the accumulation of dust, hair, and crumbs can interfere with the proper functioning of the keys. Debris can get lodged under the keycaps, causing them to become sticky, unresponsive, or fail to register a keystroke. A clean keyboard ensures a smooth, reliable, and satisfying typing experience.
Longevity of the Device
Dirt and grime can be abrasive and cause premature wear on the keycap legends (the letters and symbols). Spilled liquids, even in small amounts, can corrode the internal electronic components. By keeping your keyboard clean, you protect your investment and extend its operational life, preventing the need for a premature replacement.
Gathering Your Cleaning Supplies: The Right Tools for the Job
Using the correct tools is essential for cleaning your keyboard safely and effectively. Using improper materials can lead to damage. Before you begin, gather the following recommended supplies:
- Compressed Air: A can of compressed air with a thin straw nozzle is perfect for blowing out dust and debris from tight spaces without physical contact.
- Isopropyl Alcohol (70%): This is the ideal disinfectant and cleaning agent. A 70% solution is effective at killing germs but is less harsh on plastics and coatings than higher concentrations.
- Microfiber Cloths: Two or three soft, lint-free microfiber cloths are needed—one for damp cleaning and one for drying and polishing.
- Cotton Swabs: These are excellent for cleaning the narrow channels between keys and removing stubborn grime from tight corners.
- Small, Soft-Bristled Brush: A clean, soft brush (like a small paintbrush or a new toothbrush) can help dislodge debris that compressed air leaves behind.
- Keycap Puller (Optional): For mechanical keyboards, a keycap puller is a highly recommended tool for safely removing keys without damaging them or the switches underneath.
- Mild Dish Soap and a Bowl: If you plan to deep clean by removing and washing keycaps, you will need a bowl with warm water and a few drops of mild dish soap.
The 5-Minute Quick Clean: A Weekly Maintenance Routine
A weekly quick clean can significantly reduce buildup and keep your keyboard in great shape between deep cleanings. This simple routine takes only a few minutes and makes a huge difference.
First, always disconnect your keyboard from the computer. If it’s a wireless keyboard, turn it off. Hold the keyboard upside down over a trash can and shake it gently to dislodge any loose crumbs or large particles.
Next, take your can of compressed air. Holding it upright, use short bursts to blow air between the key rows. Work in a systematic pattern, from top to bottom, to push the debris out one side. Avoid tilting the can, as this can spray liquid propellant.
Finally, apply a small amount of 70% isopropyl alcohol to a clean microfiber cloth, making it slightly damp but not wet. Wipe down the tops of the keycaps and the keyboard’s outer frame to disinfect the surfaces and remove oils and smudges. This simple maintenance habit prevents grime from becoming a major issue.
How to Clean Keyboard Properly: A Deep Cleaning Tutorial
For a keyboard that is visibly dirty, sticky, or hasn’t been cleaned in months, a thorough deep cleaning is necessary. This process is more involved but restores the keyboard to a like-new condition. Set aside about an hour for this task.
Step 1: Disconnect and Prepare
Safety first: unplug the keyboard from your computer. For wireless models, turn them off and remove the batteries if possible. It is highly recommended to take a clear picture of your keyboard’s layout with your phone. This will be an invaluable reference when you need to put the keycaps back on in the correct order.
Step 2: Initial Debris Removal
Take the keyboard outside or hold it over a trash can. Turn it upside down and give it a few firm but gentle shakes to remove all loose debris. Use a soft-bristled brush to gently sweep between the keys to dislodge any trapped particles before using compressed air for a more targeted approach.
Step 3: Remove the Keycaps (Mechanical Keyboards)
This step is primarily for mechanical keyboards. For most laptop and membrane keyboards, it’s best to skip this, as the keys are not designed for easy removal and can be easily broken. Using a wire or plastic keycap puller, gently hook the tool under the corners of a keycap and pull straight up with a steady motion. Work your way across the keyboard, placing the keycaps in a safe place.
Step 4: Wash the Keycaps
Fill a bowl with warm water and add a few drops of mild dish soap. Place all the keycaps into the soapy water and let them soak for at least 30 minutes to an hour for heavy grime. After soaking, use a small brush or cloth to scrub each keycap individually. Rinse them thoroughly with clean water and lay them out on a towel to air dry completely. Ensure they are 100% dry inside and out before reinstallation to prevent moisture damage.
Step 5: Clean the Keyboard Body
With the keycaps removed, you have full access to the keyboard’s base. Use your soft brush and compressed air to clear away all the dust and debris that was trapped underneath. Next, dampen a cotton swab with 70% isopropyl alcohol and meticulously clean around each switch and along the frame. For the main surface, use a microfiber cloth lightly dampened with alcohol to wipe everything down.
Step 6: Reassemble and Final Wipe
Once you are certain the keycaps and keyboard body are completely dry, you can begin reassembly. Refer to the photo you took earlier and press each keycap back onto its corresponding switch. You should hear a satisfying click as it snaps into place. After all keys are back on, give the entire keyboard a final wipe with a clean, dry microfiber cloth.
Specialized Cleaning Instructions for Different Keyboard Types
Not all keyboards are built the same. The proper cleaning method can vary depending on whether you have a mechanical, membrane, or laptop keyboard.
Mechanical Keyboards
Mechanical keyboards are the easiest to deep clean due to their design. The keycaps are made to be removed, allowing unparalleled access to the keyboard deck. The main precaution is to avoid getting any liquid inside the mechanical switches themselves, as this can cause them to fail. Always apply cleaning solutions to a cloth or swab, not directly to the keyboard.
Membrane Keyboards
These are the most common type of desktop keyboard. While some keycaps can be removed, it’s often a risky process as the small plastic clips and the underlying rubber dome sheet are fragile. For these keyboards, it’s best to focus on cleaning with compressed air and using cotton swabs and a cloth to clean around the keys without removing them.
Laptop Keyboards
Laptop keyboards require the most care. The keys (often called chiclet or scissor-switch keys) are not designed to be removed by the user and are very easy to break. Furthermore, any liquid that seeps beneath the keys can directly damage the laptop’s motherboard. Always power down the laptop and unplug it before cleaning. Use compressed air at an angle to avoid forcing debris deeper inside. Clean the surface with a microfiber cloth that is only very lightly dampened.
Common Keyboard Cleaning Mistakes (And How to Avoid Them)
A few common mistakes can turn a cleaning session into a costly accident. Be sure to avoid these pitfalls.
- Using Too Much Liquid: Never spray cleaner directly onto your keyboard or oversaturate your cloth. Liquid is the enemy of electronics.
- Using Harsh Chemicals: Avoid window cleaner, bleach, ammonia-based products, or abrasive solvents. These can damage the plastic, fade the keycap legends, and remove protective coatings.
- Forgetting to Unplug It: Cleaning a connected keyboard can lead to accidental keystrokes that can delete files or change settings. More seriously, it poses a risk of electrical shorts if moisture is involved.
- Using a Standard Vacuum: The powerful suction from a household vacuum can potentially pull keycaps off or generate static electricity that can harm the keyboard’s internal components. Use a small, battery-powered electronics vacuum if you must.
- Reassembling While Wet: Trapped moisture from keycaps that aren’t fully dry can lead to corrosion or short circuits over time. Patience is key; let everything dry completely.
Tips for Keeping Your Keyboard Cleaner for Longer
Maintaining a clean keyboard is easier than performing a deep clean. Incorporate these habits to minimize dirt and grime buildup.
- Wash Your Hands: Before a long typing session, wash your hands to reduce the transfer of oils and dirt.
- Avoid Eating at Your Desk: This is the number one cause of crumbs and sticky keys. If you must eat at your desk, be extremely careful or use a keyboard cover.
- Keep a Can of Compressed Air Handy: A quick blast of air once or twice a week can prevent dust from settling and becoming compacted.
- Use a Dust Cover: When you’re away from your desk for an extended period, cover your keyboard to protect it from airborne dust.
