  • 🍕 Use with meals: crumbs, drops of coffee or tea, grease from chips - all this settles between the buttons.
  • 🐾 Pets: Wool and dander easily penetrate into crevices, especially if the laptop is placed on a sofa or bed.
  • 🌡️ Sweat and sebum: When working for a long time, your hands sweat, and greasy marks attract even more dust.

In addition, laptops the keys are located closer to each otherthan mechanical PC keyboards, so debris accumulates more densely. But for models with backlight (for example, MSI GS66 or Razer Blade) dirt is visible especially clearly - it blocks the LEDs, and the keys glow unevenly.

If you don't clean your keyboard for years, it can lead to:

  • 🔧 Sticky buttons (especially often suffer Space, Enter And Shift).
  • ⚡ Short circuit if moisture gets on the contacts.
  • 🦠 Reproduction of bacteria - studies show that there are more of them on a laptop keyboard than on a toilet seat!
📊 How often do you clean your laptop keyboard?
  • Once a month
  • Once every 3–6 months
  • Only when the buttons start to stick
  • Never cleaned

💡

If you don't have isopropyl alcohol, you can substitute it vodka without additives (abv strength not lower than 40%). But alcohol is still preferable - it evaporates faster and does not leave streaks.

Method 1: Dry cleaning (for light soiling)

This method is suitable if the keyboard is not very dirty: there is dust, crumbs or light fingerprints. It can be carried out once every 1–2 weeks for prevention.

Turn off the laptop and disconnect the battery (if possible)|Turn the laptop over at a 45° angle and shake lightly to release crumbs|Use a can of compressed air or a vacuum cleaner on low power|Ask the keys with a soft brush (such as a makeup brush)|Remove any remaining dust with a dry microfiber cloth-->

If you don't have a can of compressed air, you can use vacuum cleaner with narrow nozzle. The main thing is do not touch the keys with the nozzleso as not to damage them. Hold the vacuum cleaner at a distance of 1-2 cm from the surface.

If the crumbs are not blown out with air, try carefully prying the key from the side with a plastic spatula (pick). Don't pull up - it's better to slightly lift on one side and shake out the debris. After this, return the key to its place by pressing until it clicks.

Method 2: Wet cleaning (for greasy stains and heavy dirt)

If your keys show grease, coffee stains, or other stubborn stains, dry cleaning won't be enough. Here you will need isopropyl alcohol or special wipes for electronics.

Algorithm of actions:

  1. Turn off your laptop and unplug it (it's best to also remove the battery if possible).
  2. Soak a microfiber cloth or cotton pad in alcohol. She must be damp but not wet — excess liquid may leak under the keys.
  3. Gently wipe each key, paying attention to the sides. For crevices, use cotton swabs.
  4. Let the keyboard dry at least 10–15 minutes before turning on.

⚠️ Attention! Some laptops (eg. MacBook with Butterfly Keyboard) have extremely fragile button mechanisms. If you're unsure about the design of your keyboard, it's best not to press on the keys while cleaning—just wipe them from the top.

For gaming laptops (ASUS ROG, MSI, Acer Predator) with RGB lighting, it is important to avoid getting liquid on the LEDs. If alcohol seeps under the keys, it may cause contact corrosion and backlight flickering.

💡

Never use ordinary water for wet cleaning - it leaves a limescale deposit and can cause oxidation of the contacts. The alcohol evaporates without a trace and is safe for electronics.

Method 3: Deep cleaning with key removal (for advanced users)

If the keyboard is very dirty and conventional methods do not help, you can resort to completely removing the keys. This method requires caution, as there is a risk of damage. clamps (plastic latches holding buttons).

How to remove the keys correctly:

  1. Take plastic spatula (or a pick) and carefully pry the key from the side. Start with the corner button (e.g. Esc or Delete), since they usually have a simpler mechanism.
  2. When the key rises, do not pull it up - first slide it to the side to release the latches.
  3. Wash the keys in warm water and soap (do not use abrasives!). To clean the mechanisms under the keys, use cotton swabs soaked in alcohol.
  4. Allow all parts to dry completely (1-2 hours is best) before reassembling.

⚠️ Attention! Not all keys are removed the same way:

  • 🔠 Regular buttons (letters, numbers) are attached to 2–4 latches.
  • 🔘 Large keys (Space, Enter, Shift) have an additional metal stabilizer - they are more difficult to remove and install back.
  • 🍎 MacBook with Butterfly Keyboard (2015–2019) have a unique mechanism - remove the keys without experience highly not recommended.

If you are afraid of damaging the keyboard, it is better to contact a service center. The cost of cleaning there usually does not exceed 1000–1500 rubles, but you will be sure that nothing will break.

What to do if the key does not fit into place?

If after cleaning the button fails or does not lock, check:

1) Is the stabilizer installed correctly (for large keys).

2) Are the plastic latches bent?

3) Are there any foreign objects under the key?

  2. Gently press it against the keys and the gaps between them.
  3. Lift the mass - all the debris will remain on its surface.
  4. Repeat the procedure 2-3 times until the mass is clean.

The disadvantage of this method is that it does not remove grease stains and bacteria. Therefore, it is better to combine it with wet cleaning with alcohol.

Method 5: Ultrasonic cleaning (for the most advanced cases)

If your keyboard hasn't been cleaned for years and the buttons start to stick, you can use ultrasonic bath. This method is only suitable for removable keys — the entire keyboard mechanism cannot be placed in the bathtub!

How it works:

  • 🔊 Ultrasonic waves create microbubbles that “knock out” dirt from the most inaccessible places.
  • 🧼 A special solution or regular dish soap is added to the water.
  • ⏱️ The process takes 5-10 minutes, after which the keys are washed with clean water and dried.

⚠️ Attention! Ultrasonic cleaning is not suitable for all keys:

  • ❌ You cannot clean the keys with spraying (for example, matte or glossy surface) - it may wear off.
  • ❌ Not suitable for keys with backlit - Water can damage the LEDs.
  • ❌ Do not use for keys from soft plastic (they may become deformed).
