How to Clean LG TV Screen (Avoid Doing THIS!)

LG is one of the most popular TV brands in the world. It offers high-quality devices with excellent durability.

However, for the TV to last as long as possible, you need to know how to care for it. So, how do you clean a LG TV Screen? 

How to Clean a LG TV Screen

The best way to clean your LG TV screen is by using a dry microfiber cloth. You can also add a bit of TV screen cleaner or distilled water to the cloth. Avoid using mild detergents or paper towel products as these will damage the TV screen over time.

Let’s take a closer look at the steps you can follow when cleaning a LG TV screen. 

The first thing you need to do is get your cleaning equipment.

Find a couple of microfiber cloths and some screen cleaner. If you don’t have screen cleaner liquid, you can use a bit of distilled water.

If you have some really tough to remove marks it is OK to use a tiny drop of dish detergent in your distilled water. But in most cases just plain distilled water should do the trick.

I would not use tap water because it contains tiny minerals and other particles that can, and will scratch your screen!

Here are the steps you need to follow: 

  1. If you’ve been recently using your TV, you should disconnect it and let it cool down. Wait at least 15 to 20 minutes before cleaning your screen. 
  2. Remove all the dust with one of the dry microfiber cloths. Rub the surface carefully and in circles to avoid scratching it.
  3. Once you’ve removed dust from the surface, you can check for fingerprints. If your TV has them, you should use the screen cleaner or distilled water with a clean microfiber cloth to remove the marks. NOTE: you should never use the cleaner or distilled water directly on the screen. Instead, spray the screen cleaner on the microfiber cloth. And you don’t want your cloth soaked, just damp!
  4. Use the damp microfiber cloth to remove the fingerprint grease. Use gentle circular movements to prevent scratches. 
  5. Once you’ve finished, use another dry microfiber cloth to dry the screen. 
  6. Ensure the TV is completely dry before plugging it in. Never turn on the TV before it is fully dry. If you do, it may permanently damage the screen. 

Note: TV screens are extremely delicate, and using the wrong substance can damage them beyond repair. Stick to screen cleaners or just distilled water!

Things to Avoid When Cleaning a LG TV Screen

Many cleaning products can corrode and damage the surface of your LG TV screen. If you do not have a proper screen cleaner, you can use liquid soap diluted in water. However, don’t add anything else. 

Avoid using the following products: 

  • Bleach and other related cleaning products
  • Window cleaning products like Windex
  • House cleaners
  • Disinfecting wipes
  • Baby wipes

Many of these cleaning products contain alcohol, ammonia, etc. and over time these chemicals will start to erode the anti-reflective layer of your TV screen.

  • Paper towels
  • Toilet paper
  • Kleenex
products that will scratch your LG TV

If you use these products to clean or dry your TV screen, you risk damaging it permanently. That’s because they contain tiny fibers which end up scratching your screen.

Again, this won’t happen immediately, but over time all these micro-scratches will eventually create dull spots on the surface of your screen and it will be noticeable.

How Do You Clean the Back of a LG TV? 

Another major issue you might face with a LG TV is the dust accumulating inside and on the back.

Too much dust can overheat the TV, damaging the internal mechanism. If that happens, you’ll need to send it to service or buy a new one. 

Here’s what you can do to clean the dust from the back of your TV: 

  1. The first thing you need to do is to unplug the TV and let it cool down. 
  2. Once the TV is cool, you can turn it around to gain access to the back. 
  3. You’ll probably see dust, spider webs, and more. So, use a vacuum on the lowest setting and clean it up. 
  4. After the vacuuming, you can use a damp microfiber cloth to remove the remaining dust particles. 
  5. Repeat the process at least once a month to keep your TV in the best condition. 

Note: It is essential to prevent dust from accumulating on the back of your TV to ensure it continues running well.

How to Take Care of Your LG TV

Now you know how to clean your LG TV correctly, but that’s not all it takes to keep it in the best condition. 

If you want to maintain your LG TV, here’s what you can do: 

  1. Turn off your TV and unplug it whenever you are not using it. It will not only help you save energy, but it can increase the lifespan of your TV
  2. Surge protectors are your best allies. Electricity surges can damage the internal mechanism of your TV. 
  3. Reduce the brightness intensity during the night. That way, you are helping increase your LG TV’s lifespan. 
  4. If you use the highest contrast level of your TV, you risk reducing its lifespan. So, go to your TV’s Menu. Find the Image Settings option, and turn down the contrast. 
  5. Keep your LG TV ventilated. Avoid having it in a room without windows. Alternatively, you can use a fan to keep the air flowing. 
  6. Do not place anything underneath the TV as it can prevent adequate ventilation. 
  7. Perform the cleaning process we’ve explained in the previous steps. Do it regularly to avoid issues with your TV. 
  8. Dust is the worst enemy of electronic appliances like TVs and computers. So, keep the dust away whenever possible by vacuuming regularly. 
  9. The most recent LG TVs are less likely to burn-in (a visible mark that remains on the screen no matter what you’re watching). However, it can still happen, so avoid leaving your TV on for long periods, especially on a still image. 
  10. Try to avoid extremely low temperatures as they can produce condensation inside your TV. If this happens, the condensed air can reach an integral part of your TV, making it malfunction. 

Keeping your TV in good condition can be challenging but not impossible. So, follow these steps, and you should be enjoying your TV for a long time. 

When to Buy a New LG TV

LG TVs can usually withstand around 5-7 years of constant use. So, if you’ve been using your machine for longer than this, you might need to consider buying a new one. 

You can find LG TVs on Amazon or eBay. There are a wide variety of low-range models under 600 USD with excellent image and audio quality. 


Cleaning your LG TV screen is an essential part of keeping it in good condition. It should be done consistantly to prevent scratches or other complications. 

To recap, here’s how you can clean a LG TV screen:

  1. Unplug the TV and let it cool down. 
  2. Use a microfiber cloth to take away the dust particles carefully. 
  3. Remove any fingerprints with a damp microfiber cloth. Use a screen cleaner or diluted water with a tiny bit of liquid soap. Don’t use any other cleaning product. 
  4. Dry the screen.
