What is the best way to clean a television tube screen. One tv is a Sony
XBR maybe close to 20 years old. Another is a 12 year old Sony XBR
squared. 3rd is a 13" stereo Toshiba tv with built in DVD. Best Buy and
Circuit City say Monster Cable tv screen cleaning kit for 20 bucks is
only way to go. In the past we've used windex with ammonia sprayed on
paper towel. Toshiba says use Windex without ammonia. I can't get
through to Sony.

It's very confusing. What IS a good, safe way to clean a dusty tv
screen?
