You actually don’t need anything fancy. The official word on LCD cleaning is to use a solution of diluted isopropyl alcohol (no more than a 50% solution). Usually the rubbing alcohol you buy at a drugstore is around 90% pure and works well. Mix 1 part water and 1 part 90% isopropyl alcohol, which works out to be a perfect mix (just under 50% solution). Be absolutely sure to use a very soft cloth, such as a piece of soft flannel. Do not use paper towels, or anything more abrasive than an old worn out cotton t-shirt. Never use Windex or anything with ammonia in it, as it can etch the screen surface and can cause the plastic to go cloudy.

Another option: The next time you walk down the automotive isle at your favorite store, look for some “Auto Glass” cleaner. (It will look similar to a spray bottle of Windex, but again, never use Windex!) You will notice that “Auto Glass” cleaner contains no Ammonia - make sure of this by looking for the words “Ammonia Free” on the container. What’s better… the price is just slightly more than regular window cleaner. Now you have something to clean your LCD screen plus your car windows!

There are commercial cleaning solutions out there. In fact, we sell one at the store. In reality, it’s more expensive then making your own, though there is the convenience factor. Plus the one we sell foams nicely so you don’t have to chase it down the screen. The choice is yours of which to use!
