My mother has a RCA ColorTrak 2000 Monitor receiver Model #PKC500PR June 1985. My brother-in-law gave it to her years ago. His boss gave it to him. I think it is about 45". The screen is not what I'm used to. It's ribbed? Kinda soft. I just want to know what I can use to clean the screen. Between the grandkids finger prints and the dog nose smudges and the wax my mother dripped down the front..It really needs to be cleaned. I've used just a dry cloth. A cloth with just water. Not sure what I can use on it to CLEAN it. ANY ideas out there. I always like John S. his answers are straight forward and to the point. He will tell me to get a life and live with it..I mean this in a good way. I have also looked on line for a manual 1985 yea quess where that got me
