Always use a soft cloth. There are companies that make special cloths that can be used.

There is a screen cleaner from Kensington that costs less than four dollars. You can use eye glass cleaner. Klear Screen works really well. I have used it for years with great results. It includes a special cloth and/or a spray or special formula dampened cloth.

Advantus makes ScreenKleen. Premoistened cleaning wipes. It removes dirt, oil, smudges, and fingerprints from computer screens.

You can even make up your own solution. A 50/50 isopropyl alcohol (IPA) and water mixture. Use it with a MICRO-FIBRE cloth

Kimberly-Clark makes Kimwipes.

There is no one product or way to clean your laptops display, so experiment and find the one that works best for you.
