I need to clean the screen of my Panasonic 47WX49 RPTV and was wondering what is best to use. I had some work done a while back on it and the technician installed a free protective screen. I recently noticed dirt in between the protective screen and the regular ones. I had already taken it apart and cleaned it once using a soft cloth but I noticed more dirt after closing it back up. Is there anything that is made for this type of screen? I don't want to scratch it but the clothe didn't seem to do the job. Any help would be greatly appreciated.
