How to Clean Electronics & Screens Safely
Written by Shannon, Owner and Founder of Long Island MaidsModern screens are delicate. The wrong cleaner can permanently damage coatings and finishes. Here's how to clean TVs, monitors, laptops, and more without causing harm.
The Golden Rules of Electronics Cleaning
- Turn off and unplug before cleaning
- Use dry microfiber cloths for screens
- Dampen cloth, not the device
- Use circular motions gently
- Let dry completely before powering on
- Spray liquid directly on screens
- Use paper towels (they scratch)
- Use Windex or ammonia-based cleaners
- Use alcohol on screen coatings
- Press hard on LCD/OLED screens
Cleaning Different Devices
TVs and Monitors
- Turn off and let cool for a few minutes (warm screens smear more easily)
- Use a dry microfiber cloth to gently wipe away dust
- For fingerprints or smudges: dampen a fresh microfiber cloth with distilled water only
- Wipe in gentle circular motions—never press hard
- Use a dry microfiber cloth to remove any moisture streaks
- Clean the frame/bezel with a slightly damp cloth if needed
Laptops
Screen: Same as TVs—dry microfiber only, or barely dampened with distilled water. Never spray anything on the screen.
Keyboard:
- Turn laptop upside down and gently shake to dislodge debris
- Use compressed air between keys (hold can upright to avoid moisture)
- Wipe keys with a slightly damp cloth
- For sticky keys: use a cotton swab barely dampened with isopropyl alcohol
Trackpad: Wipe with slightly damp microfiber cloth. Dry immediately.
Smartphones & Tablets
Modern phones have oleophobic (oil-resistant) coatings. Harsh cleaners strip this coating.
- Remove case and clean separately
- Wipe screen with dry microfiber cloth
- For stubborn grime: dampen cloth with distilled water
- Apple officially recommends 70% isopropyl alcohol wipes for iPhones—but use sparingly
- Clean ports with a dry wooden toothpick (never metal)
Remotes & Game Controllers
These are among the germiest items in your home. Clean weekly:
- Remove batteries first
- Wipe surface with disinfecting wipe or cloth dampened with 70% isopropyl alcohol
- Use cotton swabs for buttons and crevices
- Let dry completely before replacing batteries
Desktop Computers
Monitor: Same as TV—dry or barely damp microfiber only.
Keyboard:
- Unplug or turn off wireless keyboard
- Turn upside down and shake gently
- Use compressed air between keys
- Wipe keys with alcohol wipe or damp cloth
- For deep cleaning: carefully pop off keys (if removable) and clean underneath
Mouse: Wipe with disinfecting wipe. Clean sensor area with dry cotton swab.
Computer case: Use compressed air to blow dust from vents. Wipe exterior with damp cloth. Never spray liquid into vents.
Cleaning Cables and Entertainment Centers
- Unplug cables before wiping with damp cloth
- Dust entertainment centers with microfiber before dusting electronics
- Use compressed air to clean dust from cable connections
- Vacuum around entertainment center regularly—electronics attract dust via static
How Often to Clean Electronics
- TV screens: When visibly dusty or smudged (every 1-2 weeks)
- Computer monitors: Weekly if used daily
- Smartphones: Daily wipe with microfiber, weekly disinfecting
- Keyboards: Weekly wipe, monthly deep clean
- Remotes: Weekly disinfecting
- Game controllers: After each use if shared, weekly otherwise

Frequently Asked Questions
Can I use eyeglass cleaner on my TV?
Not recommended. Many eyeglass cleaners contain alcohol or ammonia that can damage TV screen coatings. Stick to dry microfiber or distilled water only.
Why does my screen still look smudgy after cleaning?
You may be using too much moisture, or your microfiber cloth is dirty. Use a fresh, clean cloth and barely dampen it. Also make sure the screen is completely cool and turned off before cleaning.
Is compressed air safe for all electronics?
Yes, when used correctly. Hold the can upright (tilting can release liquid propellant). Use short bursts. Keep the nozzle a few inches from the device. Don't blow directly into charging ports.
How do I clean a laptop fan without opening it?
Use compressed air in the vents in short bursts. You can't fully clean internal fans without opening the case, but this helps reduce dust buildup. If your laptop runs hot, consider professional cleaning.
Can I use disinfecting wipes on my phone?
Apple and most manufacturers now say 70% isopropyl alcohol wipes are safe for phone exteriors. Avoid bleach-based wipes. Don't use on uncoated screens or allow moisture in ports.
