Steps to follow:


Turn off your LCD screen for cleaning. If you notice a stain or mark while using your TV or computer, you should turn it off before cleaning, and wait for a few minutes before you proceed with the cleaning process.


Firstly, remove any dust that has accumulated on our LCD screen with a feather duster or specially designed cleaning cloth. Do not use dry cloths that are too coarse as you could scratch the screen or leave fibers from the cloth on the screen.


Should the LCD screen have fingerprints, it is quite normal if they are within reach of our hands, then we need to clean it with a little alcohol. Dampen a cloth and gently clean the affected area only.


If you have a very dusty screen, it can also be removed from LCDs with a damp cloth using distilled water. However you should only dampen the cloth, do not soak it in distilled water because too much contact with liquid could affect the operation of the display.


If the LCD has grease stains or more persistent or notable dirt marks, then you can clean it with a cloth and a small amount of white vinegar. This should remove tougher stains from your TV screen, and will avoid you needing to apply excessive pressure which could also damage the screen.


Do not use any other chemicals. Always remember that these screens are very delicate so any contact with acetone, ethyl alcohol, ammonia or others could cause irreversible damage.


Do not apply liquid directly to the screen. Always slightly damp cloth and wipe inwards, away from the screen edges to prevent the liquid going into the screen.


Do not apply pressure. As we have already mentioned you should be very careful to avoid applying too much pressure to your LCD screen. Too much pressure will damage the screen quite easily. If you do need to apply some pressure to remove a stain, try to apply pressure with your palm rather than a finger, as this will distribute the pressure more evenly and minimize the risk of damage.


Do not use paper to clean an LCD as this could cause scratches. Yes this includes tissues and toilet paper.
