If you spend hours every day typing, gaming, or scrolling through code, your keyboard collects more grime than you'd think. Crumbs slip between the keys, skin oils build up on every keycap, and dust quietly settles into your switches. Beyond just looking gross, a dirty keyboard can actually affect how your switches feel and how long your keycaps stay vibrant — especially if you've invested in a cute dye-sublimated PBT set you actually want to keep looking fresh.
The good news: cleaning a mechanical keyboard properly is simple once you know the right steps. Here's everything you need.
What You'll Need
- A soft cleaning brush (a multi-purpose detail brush works great for getting between keys and around the board edges)
- Canned compressed air or a small electric air blower
- A keycap puller
- Isopropyl alcohol (90%+ recommended) and cotton swabs
- A microfiber cloth
- A bowl of warm water with a few drops of mild dish soap
- A towel for drying
Step 1: Do a Quick Daily Clean
Before any deep clean, get into the habit of a 30-second daily wipe-down. Turn the keyboard upside down and gently tap it to shake out loose crumbs and dust. Use compressed air at an angle to blow debris out from between the keys without forcing it deeper into the switches. Finish with a dry microfiber cloth over the keycap surfaces.
This quick routine alone will dramatically slow down how dirty your board gets over time.
Step 2: Remove the Keycaps
For a deeper clean, it's worth pulling the keycaps. Use a keycap puller rather than your fingers — it reduces the risk of snapping a stem, especially on smaller novelty keycaps or thinner shine-through designs.
Lay the keycaps out in rows as you remove them (or take a quick photo first) so you remember exactly where each one goes back, particularly if your set has asymmetric legends, gradient colors, or themed novelties that aren't interchangeable.
Step 3: Wash the Keycaps
Once removed, soak your keycaps in warm water with a small amount of mild dish soap for 10–15 minutes. Gently agitate the water or use a soft brush to clean off built-up oils, especially on frequently used keys like spacebar, WASD, and Enter.
A few notes depending on material:
- PBT keycaps are durable and handle soaking well — this is one of the reasons dye-sublimated PBT sets hold up so nicely over years of regular cleaning.
- PC (shine-through) keycaps can also be soaked, but avoid abrasive scrubbing on legends or printed designs to protect the finish.
- Avoid hot water, which can warp keycaps over time — stick to warm, not boiling.
Rinse thoroughly and lay the keycaps on a towel to air dry completely before reinstalling. This step matters more than people expect — putting damp keycaps back onto switches can lead to residue buildup or, in rare cases, switch issues.
Step 4: Clean the Switches and Plate
With the keycaps off, you'll likely see crumbs, hair, and dust sitting around the switches. Use your brush to sweep debris out, followed by short bursts of compressed air to clear anything wedged in tight corners.
For visible grime directly on the switch housing, lightly dampen a cotton swab with isopropyl alcohol and gently wipe the area — never the switch opening itself, and never pour liquid directly onto the board. If you're comfortable taking your board apart further (removing the plate or PCB), this is also a good opportunity to clean underneath, but it's optional for routine maintenance.
Step 5: Wipe Down the Case, Cable, and Wrist Rest
Use a microfiber cloth lightly dampened with water or a small amount of isopropyl alcohol to wipe down the keyboard case, especially along the edges where oil and dust tend to collect. If you use a wrist rest, give it a separate wipe-down or spot clean depending on the material — memory foam and fabric rests benefit from an occasional gentle hand wash.
Coiled custom cables can also collect dust in the braiding; a quick wipe with a dry cloth keeps them looking sharp.
Step 6: Reassemble and Test
Once everything is completely dry, reinstall your keycaps in their original positions. Press each one down firmly until it clicks into place, then do a quick typing test across the whole board to make sure every key registers properly.
How Often Should You Clean Your Keyboard?
- Daily: A quick brush and wipe-down, especially if you eat near your desk.
- Weekly: Compressed air pass to clear dust from between keys.
- Monthly (or every 2–3 months): A full keycap removal and wash, particularly for boards used daily.
Keeping Themed and Novelty Keycaps Looking Their Best
If your set includes hand-illustrated novelties, gradient colorways, or shine-through designs, a few extra habits go a long way: avoid harsh chemical cleaners or bleach-based products on printed legends, keep keycaps out of direct, prolonged sunlight to prevent fading, and always let them air dry fully rather than using heat to speed things up.
A clean keyboard isn't just about hygiene — it's about protecting an investment in a board you actually love looking at every day. With a regular light cleaning routine and an occasional deep clean, your keycaps, switches, and case will stay in great shape for years.
