  • •Isopropyl alcohol (at least 70%) or keyboard cleaning solution
  • •Keycap puller (if removing keycaps)

Method 1: Basic Surface Cleaning

This method is ideal for routine maintenance and quick clean-ups without removing keycaps.
  • •Step 1: Unplug the keyboard or turn it off if wireless.
  • •Step 2: Use a compressed air canister to blow out dust and debris from between the keys. Hold the canister upright and spray in short bursts at an angle.
  • •Step 3: Wipe down the surface of the keyboard with a microfiber cloth slightly dampened with isopropyl alcohol. Ensure the cloth is not dripping wet.
  • •Step 4: Allow the keyboard to dry completely before plugging it back in or turning it on.
  • •Step 5: Verify that all keys are functioning correctly by testing each key after cleaning.

For Windows 11

Windows 11 users can utilize the touch keyboard feature for testing keys.
  • •Step 1: Open the touch keyboard by right-clicking the taskbar and selecting 'Show touch keyboard button.'
  • •Step 2: Click the touch keyboard icon and test each key visually.

For Windows 10

Windows 10 users can use the On-Screen Keyboard for testing.

  • •Step 3: Click each key on the On-Screen Keyboard to verify functionality.

Method 2: Deep Cleaning with Keycap Removal

Use this method for thorough cleaning, especially if the keyboard has not been cleaned in a long time.
  • •Step 1: Unplug the keyboard or turn it off.
  • •Step 2: Use a keycap puller to gently remove the keycaps. Start with the larger keys (like Enter and Space) to avoid breaking them.
  • •Step 3: Soak the keycaps in warm water mixed with a few drops of dish soap for about 30 minutes.
  • •Step 4: While the keycaps are soaking, use compressed air to clean the keyboard base. Use a small brush to remove stubborn dirt.
  • •Step 5: Rinse the keycaps under warm water and dry them thoroughly with a soft cloth.
  • •Step 6: Once the keycaps are dry, reattach them to the keyboard, ensuring they are aligned correctly.
  • •Step 7: Test each key to confirm functionality.

If you encounter problems during or after cleaning, refer to the following solutions.
  • •Error: Keys are not responding after cleaning - Solution: Ensure the keyboard is properly connected and check for any moisture under the keys.
  • •Issue: Sticky keys after cleaning - Fix: Use isopropyl alcohol on a cloth to clean around the affected keys again.
