There are lcd cleaning kits available with include a safe cleaning spray usually made up of distilled water with a little alcohol similar to that for glasses. I use a microfiber cloth with just a few sprays of the cleaner sprayed on the cloth, not the screen. Then gently wipe with the dampened cloth. Things like papertowels are too harsh and may scratch, regular window cleaner like windex is too strong.
Some unknow product you can find somewhere in Belgium(little country next to France). Most products for glasses will be fine. I also know someone who used to clean it with vinagre but I wouldn't suggest that 😛
