Keyboard Care 101: How to Clean and Maintain Your Mechanical Keyboard

Quick answer

Clean your mechanical keyboard in stages: unplug it, dry-brush and air-blast the deck, pull and wash keycaps only if they are grimey, then spot-clean switches with isopropyl alcohol and a lint-free swab. Do the deep clean every 3–6 months, keep drinks away, and never soak the PCB or submerge switches. That routine is the core of keyboard maintenance and the simplest way to extend keyboard lifespan.

A mechanical keyboard rewards small, regular care more than one heroic deep clean. Dust, skin oil, and crumbs are the real enemies: they migrate under keycaps, gum up stabilizers, and make switches feel scratchy long before the electronics fail. The good news is that you can handle almost all of it at home with a few household items and no special tools.

This guide walks through the full process in order, from a two-minute weekly reset to a deeper teardown-free clean. It also covers keycap cleaning, switch care, and the habits that quietly shorten a board's life. If you own an EPOMAKER board, the same steps apply across models, but check the specific layout before you pull anything.

What you need before you start

Gather everything first so you are not hunting for a brush with a half-disassembled keyboard on your desk. A soft-bristled brush (a clean paintbrush or makeup brush works), a keycap puller, a can of compressed air or a rubber air blower, microfiber cloths, cotton swabs, and 90% or higher isopropyl alcohol cover 95% of jobs. For keycaps, add a bowl, lukewarm water, and a drop of mild dish soap.

Skip paper towels, which shed fibers into switch housings, and avoid household glass cleaner or acetone on plastic. If your board has a screen or knob, treat those as delicate surfaces and keep liquid away from them entirely.

• Unplug the keyboard or switch it off before any liquid comes near it.
• Photograph the layout before removing keycaps so reassembly is obvious.
• Work over a tray or towel so loose keycaps and springs do not roll away.

Step 1: Dry-clean the deck first

Turn the keyboard upside down and shake gently to dislodge crumbs, then use short bursts of compressed air at an angle across the deck. Hold the can upright to avoid propellant spray, and keep the nozzle a few inches away. Follow with a dry soft brush between keycaps, working from the top row downward so debris falls out rather than deeper in.

This is the step most people skip, and it is the one that matters most. If you wash keycaps while the deck is still full of dust, that grit ends up in the switch stems when you press keys back on.

• Common mistake: blasting air straight down into a switch, which pushes dust into the housing.
• Checkpoint: tilt the board under a light. If you still see visible crumbs, brush again before moving on.

Step 2: Remove and wash keycaps

Use a wire or ring keycap puller and pull straight up with even pressure. Work around the spacebar and stabilizer keys last, and take a photo of any key you are unsure about. ABS and PBT keycaps are generally safe in lukewarm water with a drop of mild soap; soak for 15–20 minutes, agitate gently with your fingers, then rinse and lay them face-down on a towel to air dry completely.

Never use hot water, a dishwasher, or an alcohol soak on printed or coated keycaps, since heat and solvents can warp plastic or lift legends. If you are cleaning a themed set with fine artwork, such as the EPOMAKER × vvyruus Retromania Keycaps Set, keep the soak short and skip scrubbing altogether.

• Common mistake: reinstalling keycaps while stems or inner walls are still wet.
• Checkpoint: shake each cap near your ear. If you hear water, it is not dry yet.

Step 3: Clean the plate and switches

With keycaps off, brush the plate and vacuum lightly with a brush attachment on low suction. For sticky residue around a switch, dampen a lint-free swab with isopropyl alcohol and wipe the top housing only. Do not drip alcohol into the switch, and never pour it onto the plate. If a switch feels gritty, it is usually debris or a worn internal part rather than something you can fix with liquid.

Silent and linear switches benefit most from this step because their feel depends on clean, unobstructed travel. If you are swapping in new ones, the EPOMAKER Roseveil Silent Switch Set is a 35-piece silent linear switch designed for quiet, creamy typing in office and gaming setups, so it is a sensible upgrade when a switch has genuinely failed rather than just needing a clean.

• Common mistake: spraying lubricant into a switch to fix a crunch. It attracts more dust.
• Checkpoint: press every switch with the board unplugged. Any that stick or click oddly should be noted before reassembly.

Step 4: Reassemble and test

Make sure the plate, keycaps, and your hands are dry, then seat keycaps by aligning the stem and pressing straight down until you feel a soft click. Stabilizer keys need both stems seated at once, so lower them evenly rather than at an angle. Once everything is on, plug in and test every key in a text editor or keyboard tester.

If a key does not register, lift the cap and reseat it before assuming a hardware fault. Most post-cleaning issues are a cap that is not fully seated or a stabilizer wire that popped out of its clip.

• Common mistake: forcing a keycap down at an angle and bending a switch stem.
• Checkpoint: run a full key test before you call the job done.

Habits that extend keyboard lifespan

The cheapest maintenance is prevention. Keep drinks on a separate surface and use a coaster, eat away from the desk, and cover the board with a dust cover when it is not in use. Wash or wipe your hands before long sessions, since skin oil is what turns keycaps shiny and makes them feel greasy. A weekly 30-second brush-and-shake keeps the deep clean easier when it comes around.

Store spare keycaps and switches in a dry, room-temperature container, and avoid leaving a board in direct sunlight, which can yellow plastic over time. If you travel with a keyboard, use a sleeve rather than a loose bag so the cable and knob are not stressed.

• Rotate between two boards if you type for a living; each gets half the wear.
• Keep the original box or a hard case for storage and transport.

The 6-step keyboard care routine

1. 1. Unplug and dry-brush: Disconnect the keyboard, shake out crumbs upside down, then brush the deck from top to bottom and blow short bursts of air at an angle. Checkpoint: no visible debris under a direct light before you remove any keycaps.
2. 2. Pull keycaps with a proper puller: Use a wire or ring puller, pull straight up, and leave stabilizer keys for last so you do not bend a stem. Checkpoint: photograph the layout first; a missing cap photo is the most common reassembly headache.
3. 3. Wash keycaps in lukewarm water: Soak for 15–20 minutes with a drop of mild soap, rinse, and air dry face-down. Skip heat, dishwashers, and alcohol soaks. Checkpoint: caps must be completely dry before they touch a switch.
4. 4. Spot-clean the plate and switches: Brush and lightly vacuum the plate, then wipe switch tops with an isopropyl-dampened swab. Never drip liquid into a switch. Checkpoint: note any switch that sticks or clicks oddly while the board is unplugged.
5. 5. Reassemble and test every key: Seat caps straight down, lower stabilizer keys evenly, then plug in and run a full key test in a text editor or tester. Checkpoint: reseat any dead key before assuming a hardware fault.
6. 6. Repeat and prevent: Do a deep clean every 3–6 months, brush weekly, keep drinks away, and store spare caps and switches in a dry container. Checkpoint: if keycaps feel greasy within a week, clean your hands before typing, not just the board.

EPOMAKER details that affect cleaning and care

• EPOMAKER TH99 Pro: The TH99 Pro includes a precision-engineered volume knob and a glass screen with an info page for keyboard status, battery, and time. Keep liquids and sprays away from the screen and knob during cleaning; wipe them with a dry microfiber cloth instead of a wet one.
• EPOMAKER G84 Pro: The G84 Pro uses silicone keycaps with a velvety texture and a gasket-mount structure with 5-layer acoustic foams. Silicone caps need gentler handling than standard plastic; wipe them with a damp cloth rather than soaking or scrubbing, and do not flood the foam layers with liquid.
• EPOMAKER HE68 Lite: The HE68 Lite uses shine-through PBT keycaps with a special A-RGB backlight and grease-resistant keycaps. PBT shine-through caps handle routine damp-wiping well, and the grease-resistant surface means you can clean them more often with less soap and less scrubbing.
• EPOMAKER Roseveil Silent Switch Set: The Roseveil Silent Switch Set is a 35-piece silent linear switch designed for quiet, creamy typing in office and gaming use. If a switch is genuinely worn out after cleaning, replacing it with a silent linear switch restores quiet feel without changing the rest of the board.

A mechanical keyboard does not need much, but it does need consistency. Dry-brush weekly, wash keycaps when they feel slick, spot-clean switches with alcohol only, and keep liquids at arm's length. Do that, and your board will feel and sound close to new for years.
