Your keyboard and mouse are among the most frequently touched items on your desk—collecting dust, crumbs, oils, and germs every day. Regular cleaning not only keeps your setup looking fresh but also extends the life of your devices and promotes better hygiene.
Here’s a complete guide on what to use—and what to avoid—when cleaning your keyboard and mouse safely.
Why Cleaning Matters
- ✅ Improves performance (prevents sticky keys and sensor issues)
- ✅ Reduces germs and bacteria buildup
- ✅ Extends device lifespan
- ✅ Keeps your workspace looking professional
Ideally, you should lightly clean your keyboard and mouse weekly and perform a deeper clean once a month.
What to Use to Clean Your Keyboard
1. Compressed Air (Best for Dust & Crumbs)
Compressed air is one of the safest and easiest ways to remove debris between keys.
How to use it:
- Turn off or unplug your keyboard.
- Hold it at an angle.
- Spray short bursts between keys.
Avoid shaking the can while spraying.
2. Microfiber Cloth (For Surface Cleaning)
A soft microfiber cloth removes dust and fingerprints without scratching.
- Lightly dampen with water or isopropyl alcohol (70% or higher).
- Wipe keycaps and surrounding surfaces.
- Avoid soaking the cloth.
3. Isopropyl Alcohol (70%–90%)
Perfect for disinfecting and removing grime.
- Apply to a cloth or cotton swab (never pour directly on the keyboard).
- Gently clean key surfaces and tight spaces.
- Alcohol evaporates quickly and is safe for electronics when used properly.
4. Cotton Swabs
Great for cleaning between keys and around edges.
Dip lightly in isopropyl alcohol for best results.
5. Keycap Puller (For Deep Cleaning – Mechanical Keyboards)
If you have a mechanical keyboard:
- Use a keycap puller to remove keycaps safely.
- Clean underneath with compressed air and a cloth.
- Wash keycaps in warm soapy water (let them dry completely before reinstalling).
What to Use to Clean Your Mouse
1. Microfiber Cloth
Wipe down the top, sides, and bottom of the mouse.
2. Isopropyl Alcohol
- Use to disinfect buttons and high-touch areas.
- Clean the scroll wheel carefully with a cotton swab.
3. Toothpick or Soft Brush
Helps remove debris from seams and around buttons.
4. Clean the Sensor
Turn the mouse over and gently wipe the optical sensor with a dry cotton swab.
What NOT to Use
Avoid these common mistakes:
- ❌ Bleach or ammonia-based cleaners
- ❌ Window cleaner
- ❌ Paper towels (can scratch surfaces)
- ❌ Excess water
- ❌ Spraying liquid directly onto the device
Liquids can seep inside and damage internal components.
