Hi guys.

My 8200 screen has a thumbprint size mark directly awhere the pointer device is (when its closed). Im assuming (praying) its dirt/ greese. But i cant get it off.

Ive tried using a damp cloth, swirling around and around, then using a dry cloth etc. Ive even tried fairywashingup liquid lol.
Im not keen on trying chemicals as apparently there is a anti glare filter coating or something.

Any suggestions?
