For general cleaning of the bezel, the touchscreen digitizer, and your LCD screen, you need nothing more than a clean cloth and a cleaning solution. Before you clean the screen, it is best to turn it off completely, and remove the battery and any power sources. It may sound like an overkill, but any inaccurate movement may lead to significant damage; and our approach with working on electronics has always been “better safe than sorry”.

The cloth:

Some higher-end (especially business-line) laptops come with a specific cleaning cloth, which is great; but any soft, dry, lint-free cloth will do – we found that the ones that are supplied with the eyeglasses work wonders.

What to avoid:

Avoid using paper towels, toilet paper, tissue paper, or something like your shirt to wipe the screen. These non-ultrasoft materials are very likely to scratch the display.

The cleaning solution:

Avoid using water to clean your LCD screen, or a digitizer; unless the instructions for your machine say specifically otherwise. To clean the fingerprints and/or greasy smudges use a screen cleaning solution designed for LCD screens (a non-ammonia based cleaner). Do NOT spray the solution directly onto the LCD – it can run down the LCD screen, and cause damage to electronic components behind the bezel; instead, spray a little on the cloth, and then rub the screen gently. Using general household cleaning solutions is not recommended, as they may damage the LCD surface (we have seen the effects of Windex applied directly onto the LCD, and it was not pretty).

What to avoid:

For cleaning the LCD, avoid cleaning products that contain ammonia (like Windex®); ethyl alcohol (Everclear®); alcohol for human consumption; toluene (paint solvents); as well as acetone or ethyl acetate (these are often used in nail polish remover). The reason is simple: these chemicals can react with the materials that the screen is made of or coated with.

We have an excellent screen cleaning solution that we use in-house on a daily basis, which can be purchased here for $9.99, either independently, or as a part of your LCD/touchscreen replacement order. The bottle capacity is 3.38 Oz, and it should last for several years. Each cleaner comes with the blue cleaning liquid, and a grey colored cloth.
