How to Safely Clean a Mechanical Keyboard

Mechanical keyboards are beloved by gamers and typists for their satisfying tactile feedback and incredible durability. However, because the keys sit high above the base plate, they are notorious for trapping dust, pet hair, and food crumbs. Over time, this debris can make its way inside the mechanical switches themselves, causing keys to stick or fail entirely.

Because mechanical keyboards are expensive pieces of hardware, you cannot simply throw them in a dishwasher or spray them down with harsh household cleaners. Proper maintenance requires a gentle touch and the right tools.

In this guide, we will walk you through the professional, safe method for deep-cleaning a mechanical keyboard and restoring it to factory-fresh condition.

Step 1: Unplug and Photograph

Never attempt to clean a keyboard while it is plugged into your computer. Water or cleaning solutions can easily cause a short circuit if power is running through the board. Unplug the USB cable completely.

Before you begin removing anything, take a clear photograph of your keyboard with your smartphone. You will need this image later as a reference guide when it is time to put all the keycaps back in their correct locations.

Step 2: Remove the Keycaps

Do not try to pry the keycaps off with a screwdriver or a butter knife; this is the easiest way to permanently snap the fragile plastic stems underneath.

You must use a Keycap Puller (a small wire tool that usually comes included in the box when you buy a mechanical keyboard). Gently slide the wires under opposite corners of a keycap, gently wiggle it side to side, and pull straight up. Remove every keycap on the board, placing them into a large bowl.

Note: Large keys (like the Spacebar and Shift keys) often have metal stabiliser bars underneath. Pull these off very slowly and carefully to avoid bending the metal.

Step 3: Wash the Keycaps

Fill the bowl of keycaps with warm (not hot) water and a few squirts of standard dish soap. Swirl them around gently with your hands and let them soak for about 30 minutes. The dish soap will effortlessly break down the oils left behind by your fingertips.

Drain the soapy water, rinse the keycaps thoroughly under cold tap water, and lay them out on a clean towel. They must air dry completely. Do not use a hairdryer, as the heat will warp the thin plastic.

Step 4: Clean the Base Plate

While the keycaps are drying, turn your attention to the exposed keyboard base (where all the mechanical switches are housed).

  1. Take the keyboard outside or hold it over a bin, turn it upside down, and gently shake it to dislodge the largest crumbs.
  2. Use a can of compressed air to blast out the remaining dust from between the switches. Always hold the can completely upright to prevent freezing liquid from spraying onto the circuit board.
  3. If there is sticky residue on the base plate (perhaps from a spilled drink), lightly dampen a cotton swab (Q-tip) with Isopropyl Alcohol (90% or higher). Carefully wipe around the base of the switches. High-percentage alcohol evaporates almost instantly, meaning it will not damage the electronics.

Step 5: Reassemble

Once you are 100% certain that the keycaps are completely bone-dry (even a single drop of water trapped inside a keycap stem can ruin a switch), it is time to reassemble.

Open the photograph you took on your phone in Step 1, and firmly press each keycap back onto its corresponding switch until it clicks into place. Plug your pristine, fully restored keyboard back into your PC and enjoy the satisfying typing experience.
