Learn How to Clean Lcd and Plasma Monitors

The fragility of LCD and plasma monitors is responsible for much concern when cleaning them.Which products should be used?Which are not at all?With these tips of Baixaki, you end with your doubts and also with the stains of your monitor, check it out!

CRT monitors (those of tube) have glass screen, so any glass cleaner can be used on this type of monitor.LCD already do not have this glass, and therefore are much more sensitive.Plasma, although having a glass substrate, is also quite sensitive.Therefore, cleaning them requires special care.

What is prohibited?

Do not use chemicals such as detergent, disinfectants and any other product that has acetone, ammonia, ethyl alcohol, toluene or chlorine methane as one of its components.Reactions caused by the use of these substances cause serious damage to the monitor, such as color fading or “death” of pixels (read here a special article on dead pixels).

Paper towels, toilet paper, tissues and T-shirts should also be avoided, as materials of this type can scratch the screen.Often we resort to this type of utensil, as they are almost always at hand, but they can cause permanent damage to your monitor.

Safe products

The biggest ally of cleaning, in this case, is the softness.Cotton, very soft microfiber cloths and brushes are ideal as they do not damage the surface.Combined, they are a kit capable of fighting any kind of dirt.

The edges

The edges of LCD and plasma monitors are usually made of a sturdy material, so you can wipe them with a certain force, but always be careful not to hit the screen.

Basic cleaning

To get started, we recommend that you turn off your monitor.Thus, you can observe the condition of the screen and identify the outbreaks of dirt.If you notice some more solid dirt, remove it before rubbing to avoid scratching.Use a soft brush (hard bristles can damage the screen) or compressed air for this.

If the monitor does not have finger and grease stains, and you just want to get rid of the dust that normally accumulates, a simple, soft, dry cloth should handle the message.The main tip here is to never pressure on an LCD screen.Just wipe the soft cloth with light movements and the dust should come off effortlessly.

Dripping and splashing of liquids directly on the monitor screen occur with some frequency.Clean them immediately, preferably with a dry cloth or cotton wool, as they may deform the fabric if dry.

Heavier cleaning

Fingerprints are common on monitors, virtually unavoidable.If the dry cloth is not sufficient, the best tip is to use specific products for screen cleaning of this type.They are easily found in computer stores via http://www.smartercomputing.org/. Several consecrated manufacturers have specific products for cleaning monitors.There are also solutions for cleaning electronics, also recommended as they evaporate quickly and do not stick to the screen.In this case, look for products that have anti-static component, so the dust does not stick so easily.

Just always remember to never splash the cleaning solution directly onto the screen as it can drip to the monitor’s internal components.Use the spray on the cloth to then run it on the screen.It is not necessary to exaggerate the quantity of the product.

If you do not have a specific product, water may be a solution.Use a slightly damp cloth and wipe it gently.Slightly even, a few drops of water is enough.Again, remember not to wet the screen directly, but to wet the cloth.

A damp cotton wad also helps.Just be careful to remove any remaining lint with dry soft cloth.

When using liquid products to clean a screen, be sure to remove the excess with a soft dry cloth.Also be sure to turn on the monitor only when it is completely dry.

Do not turn the plasma screens!

If you do (“turn” as a 90 ° turn horizontally, “lying” the monitor), you should wait at least six hours to lift it (due to the nature of the product).Also avoid leaving the same image frozen on the screen for a long time, since exposure of the gas cells (responsible for generating the image) to the same electrical current during high periods can mark the screen (something that does not happen in monitors and TVs with the technology LCD).

Other tips

  • Keep your notebook closed so the screen does not collect dirt;
  • If you often suffer from dirt, one tip is to search for protective covers or films.
