Frequently Asked Questions (FAQs)
No, using water can damage the internal components of your switches. Stick to isopropyl alcohol (90% or higher) or dry cleaning methods like compressed air. Water takes longer to dry and can cause corrosion.
For light cleaning, once a week is ideal to remove dust and debris. For deep cleaning, every 3 to 6 months helps prevent sticky keys and performance issues. If you spill something, clean the affected switches immediately.
Only if your keyboard is hot-swappable—these allow easy switch removal with a switch puller. If your keyboard isn’t hot-swappable, you’ll need to desolder the switches to replace or clean them properly. Always check your keyboard type before attempting switch removal.
If a switch remains sticky, try this sticky switches fix: clean it with isopropyl alcohol using a cotton swab and let it dry completely. If that doesn’t work, you may need to lubricate the switch or replace it. Sticky switches often result from spills, dust buildup, or worn-out components.
No, WD-40 is not safe for mechanical keyboard switches because it leaves a residue. Instead, use a switch-specific lubricant like Krytox or Tribosys. WD-40 can attract more dust and damage the plastic parts inside the switch.
Yes! Cleaning your switches removes dust and debris that can cause scratchy or unresponsive keystrokes. A clean keyboard feels smoother, more responsive, and lasts longer.
Wash your hands before typing to reduce oil buildup on the switches. Use a keyboard cover when not in use to prevent dust from settling. Regularly clean your desk area to minimize exposure to dirt and debris.
It’s not recommended because vacuums can generate static electricity, which may damage the keyboard’s circuitry. Instead, use compressed air or a soft brush to safely remove dust. If you must use a vacuum, choose one with anti-static precautions.
No, but if your switches feel scratchy or stiff after cleaning, a small amount of switch lubricant can improve smoothness. Lubrication is optional but recommended for a better typing feel. Avoid over-lubing, as it can make switches feel sluggish.
