The recipe is easy: Mix the Isopropyl alcohol and distilled water in equal parts (50/50) inside an empty Windex-like bottle. Do not use tap water! Doing so will leave white smears on your screen after cleaning it up because of the dissolved minerals inside the water. When finished mixing, just close the bottle using the "spray" adaptor that comes attached to it.

Next, you will need to find a good, soft piece of microfiber clothto clean your display. Avoid paper tissues at all cost! Using those on your screen would be just like scrubbing sandpaper on it and may scratch it permanently. You wouldn't want to do that right?

Now that we have everything we need, start by turning off your screen. Dampen your piece of soft cloth with your cleaning mixture and then wipe the display gently from top to bottom. Never spray liquid directly onto the LCD. When you're done, wait a few minutes to let your screen dry, and then turn it back on. Voila, you're done! Your screen should now be sparkling clean.

And if you absolutely want to use a product that was specifically made to clean LCD screens, PixelClean makes an excellent LCD cleanerthat is quite effective and not too expensive.
