Cleaning Guide
1
Unplug keyboard
Disconnect from PC first. For wireless: turn off power switch.
2
Shake & compressed air
Hold upside down and shake gently. Use compressed air at 45° between keys to dislodge crumbs and dust. Never tilt the can.
3
Remove & wash keycaps
Use a keycap puller. Soak in warm soapy water 20–30 min. Rinse well. Air dry completely (24h) before reinstalling.
4
Clean switch plate
Lint-free cloth lightly dampened with 70% IPA. Wipe between switches. Cotton swabs for tight spots. Never spray liquid directly on the board.
5
Dry completely
Allow 1–2 hours before plugging back in.
⚠️ Never use bleach or acetone. Avoid moisture near USB port. 70% IPA is safe for most surfaces.
1
Unplug / power off
Disconnect or switch off before cleaning.
2
Wipe exterior
Microfiber cloth with 70% IPA. Wipe all surfaces. Soft toothbrush for textured grips.
3
Clean sensor
Dry cotton swab on optical sensor. Never use liquid on sensor. Removes buildup causing cursor stutter.
4
Clean mouse feet
Wipe with IPA on cotton swab. If worn, replace PTFE feet sets (affordable, widely available).
5
Scroll wheel
Compressed air around wheel. Toothpick or dry brush removes debris from encoder gap for sticky scroll.
⚠️ Never submerge. Keep liquid away from sensor and scroll encoder.
1
Cloth pads
Rinse under cold water, hand wash with mild soap. Scrub gently with soft brush. Rinse thoroughly.
2
Dry properly
Pat with towel — don't wring. Lay flat to air dry 4–8 hours. No dryer or iron.
3
Hard / plastic pads
Damp cloth with mild detergent. Dry immediately. Avoid abrasives.
4
RGB pads
Unplug first. Barely damp cloth on surface. Keep water away from USB and LED strip edges.
⚠️ Wash cloth pads every 2–4 weeks. Oils degrade optical sensor accuracy.
1
Turn off & cool down
Turn off monitor. Dark screen makes dust visible. Unplug power for safety.
2
Dry microfiber first
Gentle circular motions to remove dust. No paper towels or tissues — they scratch coatings.
3
Stubborn smudges
Lightly dampen cloth with distilled water only. Or use dedicated LCD cleaner. Never spray directly.
4
Dry & power on
Second dry cloth to remove streaks. Wait 5 minutes before powering on.
⚠️ NEVER use window cleaner (ammonia) or alcohol — ruins anti-glare coatings. Never press hard on panel.
