Why Keycap Maintenance Matters
You type on your keycaps every day. Over time, skin oils, dust, food particles, and general grime build up on the surface — affecting both the look and feel of your keyboard. Regular cleaning keeps your keycaps hygienic, extends their lifespan, and preserves that satisfying texture you loved when they were new.
The good news? Cleaning keycaps is easy, inexpensive, and only takes a few minutes.
What You'll Need
- A keycap puller (wire type recommended)
- A small bowl or container
- Mild dish soap or hand soap
- Warm water
- A soft-bristle toothbrush or small brush
- A clean microfiber cloth or paper towels
- Optional: compressed air can
Step-by-Step: How to Deep Clean Your Keycaps
- Remove the keycaps: Use a wire keycap puller to gently lift each keycap straight up. Avoid plastic pullers if possible — they can scratch the sides of your keycaps. Set the keycaps aside in a bowl.
- Soak in warm soapy water: Fill the bowl with warm (not hot) water and add a few drops of mild dish soap. Let the keycaps soak for 20–45 minutes. This loosens oils and grime without damaging the plastic.
- Scrub gently: Use a soft toothbrush to lightly scrub each keycap, paying attention to the edges and the inside of the stem hole. Don't scrub too hard on the legends — especially on pad-printed keycaps.
- Rinse thoroughly: Rinse all keycaps under clean running water to remove all soap residue.
- Dry completely: Lay the keycaps out on a clean microfiber cloth or paper towels and let them air dry for at least 6–8 hours. Make sure they are completely dry before reinstalling — moisture inside the stem can damage your switches.
- Reinstall: Once fully dry, press each keycap back onto its switch. Align carefully and press straight down until you feel a click.
Quick Daily Maintenance (No Removal Needed)
You don't need to deep clean every week. These quick habits keep your keycaps in great shape between deep cleans:
- Compressed air: Blast dust and debris from between the keys every week or two.
- Dry microfiber wipe: Gently wipe the keycap surfaces to remove surface oils and fingerprints.
- Wash your hands before typing: The single most effective habit to reduce buildup. Clean hands = cleaner keycaps.
How to Deal with Shine on ABS Keycaps
ABS keycaps develop a shiny, greasy appearance over time due to skin oils. Unfortunately, once ABS keycaps start to shine, it's difficult to fully reverse. Here's what you can do:
- Regular cleaning slows down the shine but won't eliminate it entirely.
- Some enthusiasts use very fine sandpaper (2000+ grit) to lightly resurface shiny ABS keycaps. This can restore some texture, but it's a risky process and not recommended for beginners.
- The best long-term solution: Switch to PBT keycaps, which are naturally resistant to shine.
How to Protect Your Keycaps Long-Term
Prevention is always better than cure. Here are the best habits to protect your keycaps:
- Use a keyboard cover or dust cover when not in use. This keeps dust and debris off the keycaps and switches.
- Avoid eating or drinking over your keyboard. Crumbs and liquid spills are the enemy of any keyboard.
- Store spare keycaps properly: Keep them in a sealed bag or the original tray, away from direct sunlight. UV exposure can cause discoloration over time, especially on lighter colorways.
- Handle keycaps by the sides, not the top surface, when installing or removing them to minimize oil transfer.
What to Avoid
- ❌ Hot water: Can warp keycaps, especially thinner ABS sets.
- ❌ Harsh chemicals (bleach, alcohol, acetone): Can damage the plastic, strip legends, or cause discoloration.
- ❌ Paper towels for scrubbing: Too abrasive. Use a soft brush instead.
- ❌ Reinstalling wet keycaps: Always wait until fully dry to avoid switch damage.
- ❌ Dishwasher: The heat and pressure will warp and damage your keycaps.
How Often Should You Clean Your Keycaps?
- Quick wipe-down: Weekly
- Compressed air blast: Every 1–2 weeks
- Full deep clean (soak + scrub): Every 2–3 months, or whenever they start to feel grimy

A little care goes a long way. With regular cleaning and a few simple protective habits, your keycaps can look and feel great for years. Whether you're rocking a budget PBT set or a premium group-buy, proper maintenance protects your investment and keeps your typing experience at its best.
