Taking the time to deep clean your membrane keyboard ensures that it lasts longer, performs better, and remains a hygienic tool. With easy-to-follow steps, you can restore your keyboard’s cleanliness, protect it from wear and tear, and keep it free of harmful bacteria.

Why You Should Deep Clean Your Membrane Keyboard

A Neglected Keyboard is a Breeding Ground for Bacteria

Most people rarely consider how much bacteria can accumulate on their keyboards. Research has shown that a keyboard can harbor more bacteria than a toilet seat! This might sound surprising, but the combination of regular hand contact, spills, crumbs, and oils from fingers creates the perfect environment for bacteria to thrive.

In addition to bacteria, dirt and dust can also affect your keyboard’s functionality. Over time, these particles can cause sticky keys, unresponsive keys, and even yellowing of keycaps. Therefore, regular deep cleaning of your keyboard is crucial not only for maintaining a hygienic environment but also for ensuring that your keyboard performs at its best.

Removing the Keycaps for Deep Cleaning

One of the most important steps in cleaning your membrane keyboard is removing the keycaps. This allows you to clean the keys themselves as well as the surface beneath them, ensuring a more thorough clean.

How to Safely Remove Keycaps

  1. Use a Keycap Puller: Start by using the keycap puller to gently lift the keycaps from the switches. Apply gentle pressure to avoid damaging the keycaps or the switches underneath.
  2. For Larger Keys: Keys like the Space Key, Shift Key, and Enter Key may require additional care because they often have stabilizing metal rods. Use the slot screwdriver to pry these keys off gently.
  3. Store Keycaps in a Container: Once the keycaps are removed, store them in a small container to keep track of them.
  4. Shake Out Loose Debris: After removing the keycaps, shake out any loose dust and debris from the keyboard to prepare for deeper cleaning.

Cleaning the Keycaps Thoroughly

With the keycaps removed, it’s time to focus on cleaning them properly. Over time, keycaps accumulate oils, dirt, and grime that can cause them to become sticky or yellow.

Washing Keycaps Step-by-Step

  1. Prepare Soapy Water: Fill a bowl with warm water and add a few drops of dish soap to create a mild soapy solution.
  2. Soak Keycaps: Place all the keycaps in the water and let them soak for at least 30 minutes. This will loosen up dirt and oils, making them easier to clean.
  3. Scrub Keycaps: After soaking, take a toothbrush and gently scrub each keycap to remove any stubborn grime. Pay extra attention to the edges of the keycaps where oils and dirt tend to accumulate.
  4. Rinse the Keycaps: Once the keycaps are clean, rinse them thoroughly with clean water to remove any soap residue.
  5. Dry the Keycaps: Lay the keycaps on a towel in a ventilated area to dry completely. Avoid using a hair dryer on high heat, as this could warp the plastic over time.

Cleaning the Keyboard Surface and Internal Components

While the keycaps dry, it’s time to focus on cleaning the rest of the keyboard. This includes the top piece, bottom piece, and the delicate circuit sheet inside the keyboard.

Cleaning the Top and Bottom Pieces

  1. Use Compressed Air: Compressed air is perfect for blowing out dust and debris from between the keys and other hard-to-reach areas of the keyboard. Hold the can upright and use short bursts of air.
  2. Wipe Surfaces: Use a microfiber cloth dampened with isopropyl alcohol (70% or higher) to wipe down the surface of the top and bottom pieces. The alcohol will help break down oils and dirt while also sanitizing the keyboard.
  3. Use Cotton Swabs: For tight spaces around the keys and in the corners of the keyboard, dip cotton swabs in alcohol and carefully clean the hard-to-reach areas.
  4. Dry Thoroughly: Make sure to dry everything completely before reassembling the keyboard.
