Why Clean Your Keyboard

Your keyboard collects crumbs, dust, skin oils and germs every day. Over time, debris can make keys stick or stop working.

A clean keyboard also looks better and feels nicer to type on. Regular cleaning can help your laptop or keyboard last longer.

70%Strength of isopropyl alcohol wipes Apple says are safe for hard surfaces like keyboards, per its cleaning guide.

What You Need

A soft, lint-free microfiber cloth
A can of compressed air
70 percent isopropyl alcohol wipes or alcohol and a cloth
Cotton swabs for tight spaces
A soft brush, such as a clean makeup brush or small paintbrush
A keycap puller, for mechanical keyboards only

Apple notes in its guide to cleaning its products that a soft, lint-free cloth is best. Avoid paper towels, which can scratch surfaces and leave lint.

How to Clean a Laptop Keyboard

Shut down the laptop and unplug the charger and any accessories.
Hold the laptop open and tilt it upside down at an angle, then gently tap to release crumbs.
Blow out debris between keys with short bursts of compressed air, holding the can upright.
Sweep loose dust with a soft brush.
Lightly wipe the keys and surrounding area with an alcohol wipe or slightly damp cloth.
Use a cotton swab for edges and corners.
Let everything dry completely before turning the laptop back on.

Do not pry keys off a laptop keyboard. Laptop keys are fragile and can break easily.

Good to know. Apple says to keep moisture out of openings. Wring out any cloth well so no liquid drips between the keys.

How to Clean a Desktop Keyboard

Unplug the keyboard or remove its batteries.
Turn it upside down and shake it gently over a trash can.
Use compressed air between the keys.
Wipe the keys and frame with an alcohol wipe.
Clean the underside and the cable too.
Let it dry fully before plugging it back in.

Switch off wireless keyboards before cleaning. Remove the batteries if possible.

Deep Clean a Mechanical Keyboard

Mechanical keyboards have removable keycaps, which makes deep cleaning easier.

Take a photo of the layout so you can put keys back correctly.
Unplug the keyboard and remove keycaps with a keycap puller.
Soak plastic keycaps in warm, soapy water, then rinse and dry them fully.
Brush and blow out debris from the switch plate.
Wipe the plate gently with a lightly damp cloth.
Replace keycaps only when they are completely dry.

Do not soak the keyboard itself, only the removed plastic keycaps. Larger keys like the spacebar may have stabilizer wires, so remove them carefully.

What to Do After a Spill

Act fast. Quick steps can save your keyboard or laptop.

Turn off the device and unplug it right away.
Turn the keyboard or laptop upside down to drain liquid.
Blot, do not rub, with a dry cloth.
Leave it upside down to dry for at least a full day.
Do not turn it on until it is completely dry.

Sugary drinks like soda and juice leave sticky residue. If keys stay sticky or the laptop will not start, contact the maker or a repair shop.

Avoid hair dryers on high heat, which can damage parts.

What Not to Use

Bleach or cleaners with hydrogen peroxide
Abrasive powders or scrubbing pads
Aerosol sprays sprayed directly onto the keyboard
Window cleaner or household all-purpose sprays
Too much water or any liquid that could drip inside

Apple advises avoiding aerosol sprays, bleaches and abrasives. It also says not to spray cleaners directly onto products or submerge them.

How Often to Clean Your Keyboard

Task	How often
Shake out crumbs	Weekly
Wipe keys with alcohol	Weekly, or more if shared
Compressed air clean	Monthly
Mechanical keycap deep clean	Every few months

Shared keyboards at work or school need more frequent wiping, especially during cold and flu season.

Quick tip. Avoid eating over your keyboard. It is the easiest way to keep crumbs and sticky spills away.

Cleaning Shared and Office Keyboards

Shared keyboards in offices, schools and libraries pass germs between many hands. Wipe them more often, especially during cold and flu season.

Keep a pack of alcohol wipes near shared computers.
Wipe keys and the mouse at the start of each shift.
Wash your hands before and after using shared devices.
Ask your workplace about approved cleaning products for its equipment.

Some offices use washable keyboards designed for frequent cleaning. Check the label before using water on any keyboard.

Cleaning a Gaming Keyboard

Gaming keyboards often have lights, extra keys and detachable wrist rests. Unplug them, remove the wrist rest and clean it separately.

Many gaming keyboards are mechanical, so follow the keycap steps above. Keep liquid away from the lighting strips and the cable port.

Signs Your Keyboard Needs Cleaning

Keys feel sticky or slow to bounce back
Some keys do not register every press
You can see crumbs or dust between keys
The keys look shiny or greasy
There is a smell near the keyboard

Do not wait for keys to fail. A quick weekly wipe prevents most of these problems.

Clean Your Mouse and Trackpad Too

Your mouse and trackpad get just as grimy as your keyboard. Clean them at the same time.

Turn off a wireless mouse or unplug a wired one.
Wipe the top and sides with an alcohol wipe or slightly damp cloth.
Clean the bottom and around the sensor gently with a dry swab.
Wipe a laptop trackpad with a lightly dampened cloth, never a wet one.
Clean mouse pads by hand washing fabric pads and letting them dry fully.

Apple notes that compressed air can gently clear debris from the sensor window on some mice. Always check your own device instructions first.

A clean mouse tracks more smoothly and feels better to use.

Clean the Rest of Your Setup

While you are at it, clean your screen, mouse and trackpad. Each collects oils and dust too.
