A MacBook’s Liquid Retina display looks its best clean, but dust, smudges, and greasy fingerprints build up fast. The tricky part is dealing with them without scratching the glass or stripping the screen’s coating.
The short answer is simple. Dampen a soft microfiber cloth with plain water, wipe gently, and save a 70% isopropyl alcohol solution for smudges that water won’t lift. Apple approves both, and the golden rule is to put the liquid on the cloth, never on the screen.
Below we walk through cleaning a standard glass screen, the delicate nano-texture glass, the case, and the keyboard, all with Apple-approved methods.
Key Takeaways
- Turn it off: Always shut down and unplug your MacBook before cleaning to prevent electrical damage.
- Use the right cloth: Only use a clean, lint-free microfiber cloth. Paper towels can scratch the screen.
- Water first: Start with water. If stains persist, use a 70% isopropyl alcohol solution applied to the cloth, not the screen.
- Know your glass: If you have “Nano-texture glass,” use the specific polishing cloth Apple provided.
What to Clean a MacBook Screen With
Don’t grab just any cleaner from under the sink. MacBooks require gentle care to protect their coatings.
Here are the best tools for the job:
- Microfiber cloth: This is non-negotiable. Microfiber traps dust without scratching. You can use the one meant for your glasses or buy a dedicated pack. Apple sells a Polishing Cloth, but high-quality third-party options work great for standard screens.
- Screen spray: Look for sprays specifically formulated for electronics. These are usually alcohol-free and ammonia-free. They leave a streak-free finish without eating away at the display’s protective layer.
- 70% Isopropyl Alcohol: Apple officially states you can use a 70 percent isopropyl alcohol (IPA) solution for stubborn stains (Apple Support). Avoid higher concentrations, as they dry too fast and can be harsh.
- Screen wipes: Pre-moistened wipes are convenient for travel. Just ensure they are safe for coated lenses or screens.
What to Avoid When Cleaning Your Screen
Using the wrong product can permanently ruin your display. Avoid these common mistakes to keep your warranty (and screen) intact:
- Household cleaners: Never use window cleaners (like Windex), household sprays, aerosol sprays, solvents, ammonia, or cleaners containing hydrogen peroxide.
- Abrasive materials: Paper towels, napkins, and toilet paper are made of wood pulp. They feel soft to you, but they act like sandpaper on a delicate screen. Stick to microfiber cloths.
- Excess liquid: Your MacBook is not waterproof. Dripping water can seep into the bezel and fry the internal electronics. Always spray the cloth, never the device.
- Acetone: Never use nail polish remover or similar solvents. These will melt the screen coating immediately.
How to Clean Fingerprints Off a MacBook Screen
Most of the time, you don’t need chemicals. If you just have some light dust or fresh fingerprints, water and a good cloth are all you need.
- Time: 5 minutes
- Difficulty: Easy
What You’ll Need
- Microfiber cloth
- Water
1. Power Down
Shut down your Mac and unplug the power adapter. This makes it easier to see smudges against the black screen and prevents accidental keystrokes.
2. Wipe Away Dust
Take your dry microfiber cloth and gently wipe the screen. This removes loose dust particles that could scratch the glass if you press down on them later.
3. Dampen and Wipe
Lightly dampen a corner of your cloth with water. It should be moist, not dripping. Wipe the screen gently in a side-to-side motion. Do not scrub hard. Let it air dry.
How to Clean MacBook Screen Stains
If water didn’t do the trick, you likely have oily residue or dried food spots on the display. Here is how to deep clean a MacBook screen safely using Apple-approved methods.
- Time: 10 minutes
- Difficulty: Easy
What You’ll Need
- Two microfiber cloths
- 70% isopropyl alcohol (or specialized screen cleaner)
1. Prepare the Device
Turn off the MacBook and unplug it. Ensure the screen is cool to the touch.
2. Apply Solution to Cloth
Spray your 70% isopropyl alcohol or screen cleaner onto a clean microfiber cloth. Never spray directly on the screen.
3. Buff the Stains
Gently wipe the screen with the damp cloth. Focus on the stained areas but keep your pressure light.
4. Dry Immediately
Use a second, dry microfiber cloth to buff the screen dry. This prevents streaks and removes any lingering moisture.
Cleaning the Touch Bar and Touch ID
If you have a MacBook Pro with a Touch Bar or Touch ID sensor, clean these exactly like the screen. Apply water (or 70% isopropyl alcohol) to a cloth and wipe gently. Do not let moisture get into the crevices between the Touch Bar and the keyboard.
How to Clean a Nano-Texture Glass Screen
If you paid extra for the Nano-texture glass (available on some iMacs and high-end displays), you must be extra careful. This glass is etched to reduce glare and holds onto oil differently.
Apple strictly advises using only the polishing cloth that came with your Mac.
- Turn it off: Shut down the computer and unplug it.
- Dry wipe: Use the included Apple polishing cloth to wipe away loose dust and oil.
- Damp wipe (if needed): Still see marks? Lightly dampen the same polishing cloth with water and wipe again.
- Spot-treat smudges: For anything water won’t lift, dampen the cloth with a 70% isopropyl alcohol solution and buff gently.
- Air dry: Let the screen dry completely. Never use paper towels or an unauthorized cloth on this etched glass, as either can scratch it.
How to Clean the MacBook Case
While the screen is the star of the show, the outside of your MacBook gets gross, too.
- Unplug: Ensure the device is off.
- Wipe down: Dampen a microfiber cloth with water or 70% isopropyl alcohol.
- Clean exterior: Wipe the top and bottom case. Be careful near the ports (USB-C, MagSafe, Headphone jack). You do not want liquid getting inside the machine.
- Dry: Wipe dry with a clean cloth.
How to Clean a MacBook Keyboard
Keyboard keys trap dust, crumbs, and oils from your fingers. These oils can actually transfer onto your screen when you close the laptop, creating permanent “keyboard marks” on the glass. We’ll show you how to clean your keyboard properly.
- Tilt the MacBook: Hold the MacBook open at a 75-degree angle (not quite vertical).
- Spray compressed air: Use compressed air to spray the keyboard from left to right. Keep the straw about half an inch from the keys, and don’t turn the can upside down while you spray.
- Rotate: Turn the MacBook to its right side and spray again. Then turn it to its left side and repeat. This dislodges crumbs trapped under the keycaps.
- Disinfect: Gently wipe the keycaps with a 70% isopropyl alcohol wipe or Clorox Disinfecting Wipe. Wring it out first so it isn’t dripping wet.
If a key still sticks or won’t respond after cleaning, Apple recommends taking the MacBook to an Apple Store or Authorized Service Provider rather than prying off the keycap yourself.

Final Thoughts
Keeping a MacBook screen clean comes down to one habit. Put the liquid on the cloth, never on the screen. Start with plain water, and reach for a 70% isopropyl alcohol solution only when a smudge won’t budge.
Keep paper towels, household sprays, and anything abrasive well away from the glass. Do that, and the display will stay clear for years.
