No one wants to settle in for a movie night only to be distracted by smudges and fingerprints on their TV screen. While it’s tempting to reach for the nearest cleaning spray, some of these chemicals can damage your flat screen. Our guide will walk you through the best practices for safely removing fingerprints and other marks from your TV screen, giving you a crystal-clear viewing experience without harming your TV.
Proper Cleaning Tools for Flat Screen TVs
Modern flat-screen TVs come in several varieties, including LED, LCD, and plasma. While these technologies differ in how they produce images, they all have delicate screens that require gentle handling. These screens are sensitive to both pressure and chemicals—using the wrong cleaning methods or products can lead to permanent damage, such as scratches, discoloration, or even electrical shorts. Instead of harsh chemicals, try the following products and methods.
Microfiber Cloths
Microfiber cloths are soft, lint-free cloths designed to attract dust and remove smudges without scratching the screen. We recommend using two: one for dry dusting and another for damp cleaning. Wash these cloths regularly to keep them soft and effective.
A common mistake is using a single damp cloth for everything. As demonstrated on This Old House, the two-towel method works best: use one microfiber cloth dampened with your cleaning solution to loosen smudges, then follow immediately with a dry microfiber cloth to detail the surface streak-free. Most homeowners make the mistake of trying to clean and dry with the same wet towel, which just pushes moisture around the screen.
Pro Tip: Garry, a professional window cleaner featured on This Old House, explains why microfiber is his top pick: “Even though the towel is damp or wet, it’ll still dry perfectly…Even if you’re not a pro, you can clean like a pro with the microfiber towel.”
Cleaning Solutions
Distilled water should work for most of your flat-screen cleaning needs. For tougher marks, mix distilled water and a small amount of mild dish soap. Avoid harsh chemicals, window cleaners, or abrasive solutions, as these can damage the screen’s protective coating. Products containing alcohol or ammonia are particularly harmful, and we recommend avoiding them at all costs.
Canned Air
You can use canned air to blow dust away from hard-to-reach areas. Hold the can upright and keep it at least six to eight inches away from the screen to avoid causing more damage.
Step-by-Step TV Cleaning Process
Follow these steps to safely and effectively clean your flat-screen TV screen.
Powering Down and Unplugging
Always start by turning off and unplugging your TV. This step is important for your safety and makes it easier to see dirt and smudges on the dark screen. Trying to clean a warm screen can cause streaking, so let the TV cool down if it’s been on for a while. This also helps prevent thermal shock.
Why Unplugging Matters: Simply pressing the power button on your TV doesn’t fully cut electricity to the device. As TOH electricians have explained, when an appliance or device is plugged in, the on/off switch isn’t really turning it on and off — power is still flowing through the system. Unplugging ensures no current reaches the screen, making it safe to wipe down with a damp cloth.
Assessing the Screen’s Condition
Take a close look at your screen and note any particularly stubborn marks or areas with heavy fingerprints. This will help you avoid unnecessary wiping on clean areas and reduce the risk of spreading dirt across the screen.
Dusting the Screen
Start with a dry, clean microfiber cloth. Gently wipe the screen in circular motions to remove dust and loose particles. This may be enough for lightly soiled screens. If your screen is really dirty, removing surface-level dust helps avoid scratches during more intensive cleaning. We recommend dusting your screen regularly to reduce the need for these deep-cleaning sessions.
Removing Fingerprints and Smudges
If your screen is still dirty, slightly dampen a clean microfiber cloth with distilled water. Wring it out thoroughly—it should be damp, not wet. Don’t spray the screen directly with the spray bottle, as this can lead to water seeping through the seal and damaging your flat screen.
Wipe the screen in gentle circular motions, focusing on areas with fingerprints or smudges. Avoid applying pressure, as this can damage the screen. We recommend using a completely clean cloth for best results.
Tackling Stubborn Marks
For persistent stains, create a solution of distilled water and a small amount of mild dish soap. Use a ratio of about 100 parts water to 1 part soap (2 teaspoons of soap in 32 ounces of water).
Apply this solution to a clean microfiber cloth, not directly to the screen, and wring it out. Gently clean the affected areas, then wipe with a cloth dampened with only distilled water to remove any soap residue.
Cleaning Around the Screen
A thorough TV cleaning routine should extend beyond just the screen for optimal performance and longevity.
- TV stand and surrounding area: Dust these surfaces regularly to prevent particles from settling on the screen. Use appropriate furniture polish for wood stands. A damp cloth is usually sufficient for other materials.
- TV vents: Use a can of compressed air or soft brush attachment on a handheld vacuum to gently clean the vents. This can help prevent the TV from overheating.
Advanced Cleaning Techniques for Flat-Screen TVs
Use these advanced techniques for tougher cleaning challenges.
Using Specialized TV Cleaning Kits
Commercial TV cleaning kits can be effective for regular maintenance. These kits typically include a microfiber cloth and a cleaning solution specifically formulated for electronic screens. Always follow the manufacturer’s instructions.
Dealing with Oily Residues
A solution of equal parts distilled water and white vinegar can be effective for screens with oily marks from fingerprints or other sources. Apply this mixture to a microfiber cloth and gently clean the affected areas. Follow up with a water-dampened cloth to remove any vinegar residue.
Maintaining a Clean TV Screen
Regular maintenance can reduce the need for deep cleaning and keep your flat-screen TV looking its best.
Regular Dusting Schedule
Implement a weekly dusting routine using a dry microfiber cloth. This simple step can prevent dust buildup and reduce the frequency of more intensive cleaning sessions. Consistency is key—regular light cleaning is far less likely to cause damage than sporadic intensive cleaning.
Technique Tip: When dusting your flat-screen TV, push the microfiber cloth in one continuous motion across the screen rather than wiping back and forth. This approach, recommended by TOH for delicate surfaces, picks up dust more effectively without redistributing particles or pressing grit into the screen’s coating.
Preventing Fingerprints and Smudges
Educate household members about not touching the screen. Place the TV remote in a visible, easily accessible location to discourage reaching across the screen. For households with children, set clear rules about TV handling. A screen protector can further guard against fingerprints and smudges.
Extending Your TV’s Life
Regular cleaning extends the life of your flat-screen TV, and additional precautions can help even more:
- Avoiding overuse: Power down your TV when not in use. This reduces strain on the electrical components and prevents static images from getting burned into the screen. Many TVs come with a sleep timer function to help with these issues.
- Proper ventilation: Make sure your TV has adequate ventilation. This prevents overheating and can extend your device’s lifespan. Avoid placing the TV in enclosed spaces or against walls that block vents.
- Temperature control: Avoid placing your TV in rooms or areas that get extreme temperatures. Don’t put it directly above or against a heater or air conditioning vent.
- Using a surge protector: A surge protector safeguards your TV against power surges that can cause irreversible damage. It’s a small investment that provides significant protection.
Pro Tip: If your flat-screen TV is in a bathroom or other humid space, take extra precautions. Austin Lowery of California-based Jetson Systems, who has designed watertight TV enclosures, notes that “a consistently steamy and damp environment will surely cut its life span.” Consider recessing the screen into a wall niche with a silicone-sealed, fog-proof glass frame to protect your investment from moisture damage.
Common Mistakes To Avoid
Be aware of common cleaning mistakes to help protect your flat-screen TV from damage.
- Excessive pressure while cleaning: Too much pressure can damage the delicate pixels in your screen. Always use a light touch, letting the cleaning solution and microfiber cloth do the work. If a mark doesn’t come off with gentle wiping, it’s better to leave it than risk damaging the screen with excessive force.
- Harsh cleaning products: Never use window cleaners, all-purpose cleaners, or any products containing alcohol, ammonia, or abrasive ingredients. These can strip the protective coating from your screen, leading to permanent damage.
- Ignoring cleaning instructions: Always refer to your TV manufacturer’s cleaning instructions. Ignoring these guidelines can void your warranty and potentially damage your device.
