Keeping your laptop keyboard clean improves its functionality and lifespan. It also makes using your laptop a more pleasant experience.

In this comprehensive guide, you’ll learn how to clean your laptop keyboard safely and effectively.

Materials and Tools Needed for Cleaning a Laptop Keyboard

Before cleaning your laptop keyboard, ensure you have the right cleaning materials and tools. This prevents damage to your laptop.

Cleaning Materials

  • Compressed Air – Helps blast away loose external debris between and around the keys. Choose an air duster specifically for electronics.
  • Cotton Swabs – For wiping away dirt in tight spaces between the keys. Opt for lint-free ones.
  • Isopropyl Alcohol – High concentration (90% +) works best for disinfecting between keys.
  • Distilled Water – For mild, safe cleaning to avoid corrosion from tap water minerals. Use sparingly.
  • Microfiber Cloth – A smooth, non-abrasive lint-free cloth ideal for wiping down laptop surfaces. Avoid paper towels.
  • Disinfecting Wipes – For convenient disinfecting of external laptop surfaces. Check they are plastic-safe first.

Tools

  • Vacuum Cleaner Attachment – For vacuuming dust and debris around and between the keys.
  • Soft-Bristled Toothbrush – To gently sweep away debris around and between keys.
  • Keycap Puller – Required for removing keycaps for deep cleaning the keyboard.
  • Tweezers – Help remove stubborn debris lodged between keys.

Cleaning a Laptop Keyboard – Step-by-Step

Follow these steps to thoroughly clean your laptop keyboard safely:

1. Prep Your Work Area

Clear a flat, spacious area to work on and lay down some paper towels to protect the surface from any moisture and grime.

Power down your laptop first and remove any connected devices and cables. Remove any large debris around the keyboard keys first so it doesn’t get lodged deeper inside.

2. Vacuum The Keyboard

Use a handheld vacuum cleaner attachment to vacuum all around, between and underneath the keys to remove loose external debris.

Hold the attachment nozzle parallel to the keyboard surface as you vacuum. Work slowly and methodically. Pay extra attention to the gaps between keys where crumbs love to hide.

3. Inspect for Stuck Debris

Inspect if any debris is lodged deeper between the keys, around the edges or stuck underneath keycaps.

For stuck debris around key edges, use tweezers to grip and remove it. For stuck debris between keys, slide a business card between keys to loosen and remove it.

4. Blast Pressurized Air

Use short bursts of compressed air to blast away stubborn debris lodged between keys or around hinges.

Tilt your laptop to help dislodge blasted debris. Never use liquids before electronics air dusters. Avoid blowing air directly at screen and vents.

5. Disinfect With Isopropyl Alcohol

Moisten a microfiber cloth or cotton swab with isopropyl alcohol (90%+ concentration) and rub gently between keys and around hinges to disinfect.

Isopropyl alcohol dissolves oil and grease buildup quickly. Be extremely careful to avoid dripping any liquid directly on the keyboard circuitry.

6. Scrub Keys With Toothbrush

Use a soft-bristled toothbrush dipped in distilled water to scrub away grime buildup on keycaps.

Make sure no moisture gets between the keys or anywhere except the keycap surface. Clean one key at a time, wiping away liquid immediately with a dry microfiber cloth.

7. Sanitize External Surfaces

Moisten a microfiber cloth with a 50/50 solution of isopropyl alcohol and distilled water. Gently wipe down all external laptop surfaces.

Alternatively, use disinfecting wipes to conveniently sanitize external surfaces. Avoid harsh scrubbing or using too much liquid.

8. Flush Keys With Distilled Water

For greasy keys, flush with distilled water using an electronics-safe silicone squirt bottle to get rid of oil and grime from fingertips.

Tilt laptop gently while squirting water so it runs out. Absorb all moisture immediately with a microfiber cloth before moisture gets inside keyboard.

9. Air Dry

Point a fan towards keyboard to speed up drying time. Let it air dry for at least 24 hours before reattaching keycaps or powering on your laptop. Moisture trapped can short circuit the keyboard.

10. Clean Between The Keys

Once fully dry, use cotton swabs dipped in isopropyl alcohol to gently clean in tight spaces between keys and hinges.

Bend and trim swab tips to suit tight gaps. Take your time and scrub any hidden dirt and grime away. Edge keycaps can hide plenty of gunk.

11. Clean Keycaps

Pop off keycaps using a keycap puller tool one at a time and clean debris buildup underneath using cotton swabs and isopropyl alcohol.

Soak any stubborn stains on keycaps using warm water mixed with a gentle soap before scrubbing clean. Rinse with water then dry immediately with a cloth.

12. Replace Keycaps

Before replacing keycaps, clean the internal keyboard plate using swabs and isopropyl alcohol.

Align keycap clips carefully before gently snapping them back into place. Improper alignment can break the flimsy clips. Work methodically and patiently.

13. Test Keyboard

Reconnect your laptop, power it on and test every key. Ensure no keys are still stiff or sticky and every key types properly on screen.

If keys respond erratically, don’t type properly or make clicking sounds, you may have moisture trapped – power off and let dry for longer.

How Often Should You Clean Your Laptop Keyboard?

How often you clean your laptop keyboard depends on how much you use your laptop and how quick dust and grime accumulates.

As a general rule of thumb:

  • Perform a quick external cleaning of keys once every week using air dusters and disinfectant wipes.
  • Thoroughly clean between keys, under keys and external surfaces once every 1-2 months depending on your usage.
  • Plan deep cleaning sessions less frequently – once every 6 months or year. This involves taking all keycaps out for cleaning.

Adjust cleaning frequency accordingly:

  • If you rarely use your laptop – Deep clean every 8-12 months. Quick clean every 2-3 months.
  • If you use laptop heavily and eat around it – Deep clean every 4-6 months. Quick clean weekly.

After prolonged idle periods – Always do a quick cleaning session before using your laptop again.
