Cleaning TFT (LCD) screens

Viglen Product Marketing give the following advice:

"For cleaning TFT screens, it is important to keep moistness off the unit because surplus liquid or foam can be easily "sucked" into the screen through capillary action. Once the moisture gets in there, it isn't coming out.

A standard yellow duster is normally suitable. Really stubborn fingerprints and biro marks should be treated with care since pressure on the screen could damage the liquid crystal cell behind. If it's all getting too much, you can try spraying some screen cleaning fluid onto the cleaning cloth (avoiding having free liquid slopping about) and gently buff the screen."

Note: it appears that almost every manufacturer of TFT screens has their own - different - recommended method of cleaning! All agree that care must be taken not to put pressure on the screen, that use of abrasives (for example, paper towels) should be avoided and that liquids should not be applied directly to the screen. Virtually all recommend against the use of ammonia-based cleaners and solvents such as acetone. Some suggest using a soft, lint-free cloth slightly moistened with just water, or dilute vinegar - but do check beforehand for cleaning instructions in the manual or on the manufacturer's Web site.
