Plasma or LCD flat screens need more attention than good old televisions that could be cleaned with window cleaner and a paper towel. Note that it is possible to clean these screens with a microfiber cloth, a vinegar mixture and repairing scratches.
Steps
Method 1 of 3: Clean with a microfiber cloth

Step 1. Turn off the television
You don't want to interfere with the pixels when they're present and the dark surface will allow you to see dirt, dust, and grime better.

Step 2. Find a microfiber cloth
It is the same type of cloth that is used to clean glasses. They're great for screens because they don't lint.

Step 3. Wipe the screen
Use the cloth to gently remove visible stains.
- Do not press too hard on the screen if the dirt does not come off right away. Just go to the next method.
- Do not use paper towels, toilet paper, or old pieces of cloth. These materials are more abrasive and can therefore scratch the screen. Plus, they fluff.

Step 4. Examine the screen
If it looks clean, you won't need to clean it anymore. If you see streaks, stuck-on dirt, or the like, use the following tips to make it shine.

Step 5. Clean the frame
It's less fragile than the screen itself, so use a microfiber cloth or duster to wipe it down.
Method 2 of 3: Clean with vinegar and water

Step 1. Turn off the television
Again, you don't want the pixels to interfere and you'll see imperfections better if the screen is turned off.

Step 2. Prepare a mixture of 50% vinegar and 50% water
Vinegar is a natural detergent, which makes it a cleaner product that is more environmentally friendly, less dangerous and less expensive than others.

Step 3. Dip a microfiber cloth into the mixture
Then gently wipe the screen. If necessary, press lightly, rubbing the spots that need it in circular motions.
- Do not pour or spray the mixture directly on the screen to avoid damaging it irreparably.
- If you prefer to buy an LCD screen cleaner, they are available in supermarkets and specialty stores.
- Do not use products containing ammonia, ethanol, acetone or trichloroethane. These products can damage the screen by cleaning it a little too much.

Step 4. Use another dry microfiber cloth to wipe the screen
If you let it air dry, it will leave traces.

Step 5. Clean the screen bezel
If it needs more than a wipe of a rag, dip a paper towel in the vinegar mixture and rub gently. Use another sheet to wipe it off.
Method 3 of 3: Repair scratches on flat screens

Step 1. Check the warranty
If the scratch is very large and your device is still under warranty, you might be better off getting it replaced. Trying to fix it could make matters even worse, as it will no longer be under warranty if you damage it.

Step 2. Use a repair kit
They are available in specialized stores and supermarkets. This is the safest method.

Step 3. Use petroleum jelly
Dip a cotton ball in it and lay it over the scratch.

Step 4. Use hairspray
Buy clear hairspray and spray directly on the scratch. Leave to dry.
